Topics in this chapter include: ◆ ◆ ◆ Architecture ............................................................................................................ 14 Backup ................................................................................................................... 16 Restore and recovery............................................................................................... 17 Introduction 13 Introduction Architecture The Avamar Plug-in for DB2 works with the Avamar server and the DB2 API to back up DB2 databases and archive logs from a DB2 server to the Avamar server. The Avamar Plug-in for DB2 serves as a backup module and the Avamar server as a storage device. The Avamar Plug-in for DB2 supports backups and restores of DB2 single instance configurations and DB2 configurations that implement DB2 database partitioning feature (DPF). Each DB2 server requires the installation of the Avamar Plug-in for DB2 and an Avamar file system client. You back up and restore DB2 databases by using Avamar Administrator. The Avamar Plug-in for DB2 also provides a command line interface (CLI) for backups and restores. Appendix B, “Command-Line Interface,” provides more information about the Avamar Plug-in for DB2 CLI. The following figure shows an Avamar Plug-in for DB2 configuration that backs up database files from an AIX client platform to an Avamar server.

Avamar server ddmaint utility DD Boost API metadata Data Domain Network Windows or Linux server Avamar Administrator Avamar client IBM DB2 Avamar Plug-in for DB2 Avamar Client for AIX DD Boost API GEN-001813 Figure 2 Avamar Plug-in for DB2 and Data Domain configuration The Avamar client uses the “DD Boost” application programming interface (API) for backups to and restores from the Data Domain system. The installation of Avamar Plug-in for DB2 automatically installs the DD Boost application programming interface (API) on the Avamar client. The installation of the Avamar server software automatically installs the DD Boost API on the Avamar server. To back up DB2 data to a Data Domain system, you select a Data Domain system from the user interface. Chapter 3, “Backup,” provides more information. Metadata for the backup is stored on the Avamar server. You restore backed up data from a Data Domain system the same way you restore data from the Avamar server. There are no extra steps. You follow the same restore procedure whether the data is located on the Avamar server or a Data Domain system. The EMC Avamar and Data Domain Integration Guide provides more information about Data Domain systems. Architecture 15 Introduction Avamar client software The computer that runs the DB2 Universal Database requires the following software: ◆ The applicable platform-specific Avamar file system client: Avamar Client for AIX, Avamar Client for Linux, or Avamar Client for Windows. ◆ Avamar Plug-in for DB2 The Avamar Plug-in for DB2 includes the two main components. ◆ On AIX and Linux, avdb2 binary and libdb2_avamar.so (shared library) ◆ On Windows, avdb2.exe and avdb2.dll (Dynamic Link Library) The avdb2 binary or executable performs browse, backup, restore, and cancel operations on DB2 databases that belong to a “DB2 instance.” Backup The Avamar Plug-in for DB2 supports full backups of DB2 databases and database partitions. You can perform either on-demand or scheduled backups while the database is online or offline. Online backups An online backup is performed while the database is active. During this type of backup, users and applications can connect to the database and perform transactions. Online backups can either include or exclude archive logs. To reduce the backup window, you can exclude the archive logs from the database backup by specifying the Exclude archive logs in ONLINE backup option. Then include the archive logs in a file system backup. “On-demand backup” on page 45 provides more information about the Exclude archive logs in ONLINE backup option. Offline backups An offline backup is performed while the database is inactive. During this type of backup, no connections to the database are allowed. Chapter 3, “Backup,” provides more information. Backups in a DPF environment are performed from the catalog partition only. DB2 partition backups Avamar Plug-in for DB2 supports partition backups in configurations which use DPF. A DPF configuration allows you to partition a database across multiple servers or within a large Symmetric Multi-Processor (SMP) server. The partition where you execute the CREATE DATABASE command is called the catalog node or partition. The catalog partition is where the backup process runs. The catalog partition contains the following table spaces in addition to user-defined table spaces: 16 ◆ SYSCATSPACE — A table space that describes the database itself. ◆ TEMPSPACE1— A table space used for temporary storage by the database server during operations on the database. ◆ USERSPACE1 — The default table space, which contains all tables created by the user. EMC Avamar 6.1 for IBM DB2 User Guide Introduction All other partitions are called non-catalog nodes or partitions. The Avamar Plug-in for DB2 backs up database partitions that are local to the catalog node or remote (located on remote cluster nodes). To back up database partitions, the Avamar Plug-in for DB2 backup process first connects to the database that is selected for backup and runs a query to determine configuration details. ◆ If the query determines that database partition is local, the backup process continues on the DB2 server. ◆ If the query determines that the database partition is located on a remote cluster node, DB2 forwards the backup request to the remote cluster node, and then starts the backup. Backing up a partition from a non-catalog node You cannot perform a database partition backup from a non-catalog node. Doing so returns the following error: Cannot perform multi-partition backup. The catalog node for the database is not present on this server. Backing up a partition when a node is offline You cannot back up a node in a multi-partition configuration unless all nodes are online. A multi-partition backup fails if one or more nodes is offline. The backup failure returns the following error messages for this type of failure: 2012/4/1-13:14:07.21048 [avdb2ctlplugin_assist] snapup: return from db2 API 2012-4-1 18:44:07 avdb2 Error <0000>: snapup: failed to create backup of database [db2inst1/AVAMAR2]. db2 errcode -1170 2012-4-1 18:44:07 avdb2 Error <9018>: DB2 returned error -1170 2012/4/1-13:14:07.21122 [avdb2ctlplugin_assist] retire_manager: force terminate Restore and recovery You restore and recover a database only while the database is offline. You cannot restore and recover a database that is online with connections. The restore and recovery operation automatically establishes a connection to the specified database. Once the restore operation completes, this connection is terminated. Restore and recovery 17 Introduction The Avamar Plug-in for DB2 supports DB2 database restores from both online and offline backups. You can identify whether the backup is an online or offline backup by its file name prefix. The Avamar Plug-in for DB2 uses a prefix to specify the type of backup. The following table lists the prefix-naming convention for each backup type. Table 2 Database backup types Type of backup File name prefix Example file name Offline backup of a database c- c-DBname Offline backup of a partition c- c-DBname-PartitionNumber-Hostname Online backup of a database with archive logs hl- hl-DBname Online backup of a partition with archive logs hl- hl-DBname-PartitionNumber-Hostname Online backup of a database without archive logs h- h-DBname Online backup of a partition without archive logs h- h-DBname-PartitionNumber-Hostname The Avamar Plug-in for DB2 restores and recovers database and table spaces according to the operations allowable by the DB2 API. The following table lists the types of restore and recover options you can specify for a restore operation. Table 3 Restore and recover options Option Description Backup type Restore and Recover Restores the backup and rolls the database forward by using the archive logs. When you specify this option, you also must select a Recovery Type option. Online Restore Only Restores database files only. Online or offline Restore only archive logs from ONLINE backup Restores archive logs only. Online The Avamar Plug-in for DB2 includes database recover options that enable you to roll the database or table space forward. The following table lists the recovery type options. Table 4 Recovery types 18 Recover option Description End of Logs Rolls the database forward to the end of log files. Point in Time Recovers the database to a specific time (year, month, day, hour, minute, and second). End of Backup Rolls the database forward to the end of the backup. This option is available for backups of DB2 9.5 databases and later. EMC Avamar 6.1 for IBM DB2 User Guide Introduction Restore locations You can restore a database to its original location, to a different location on the original client, or to a different client altogether. A restore to a different location is commonly referred to as a redirected restore. When you restore a database to a different location, you can only select one database for the restore operation. When performing a redirected restore, the restore target can be: ◆ The same client from which the backup was originally taken. In this case, the redirected restore operation creates a clone of the original database. The new database contains the same contents of the original database. ◆ A different client. To perform a redirected restore to a different client, the operating system version and DB2 version on the target client must be the same version as on the source client. A redirected restore sets the table space container path to the DB2 defaults. If the database contains a user-defined container path to a table space, the redirected restore redefines the default path. This process requires adequate space on the partition. The Avamar Plug-in for DB2 supports redirected restores only for databases without automatic storage on the AIX and Linux platforms. Table space restore and recovery The “granular recovery” feature enables you to restore one or more table spaces from a full database backup. To use the granular recovery feature, LOGARCHMETH1 must be set to LOGRETAIN and a full database backup must exist. During a full database backup, the Avamar Plug-in for DB2 runs the DB2 LIST HISTORY command, which compiles a list of table spaces that were backed up. The Avamar Plug-in for DB2 then uses this list of table spaces for granular recovery operations. A table space restore and recovery is performed while the database is online or offline. The exception is the SYSCATSPACE table space. A SYSCATSPACE table space restore and recovery must be performed while the database is offline. You must use the rollforward command to manually roll the table space forward after you restore a table space from an offline backup or a DPF environment. An end of backup or point-in-time recovery of a table space leaves the table space in a backup pending state. When a table is in a backup pending state, the database is read-only. No modifications can be made to the table space. After performing an end of backup or point-in-time recovery of a table space, you must perform an online or offline backup to reset the table space state. You can restore a renamed table space by using the renamed_tablespace_list option. Restore and recovery 19 Introduction Granular recovery restrictions The following restrictions apply to the granular recovery feature: ◆ The Avamar Plug-in for DB2 does not support the end of logs, point-in-time, or end of backup recovery types for a table space in a DPF environment. ◆ DB2 does not support restores of a table space to a database other than the one from which the backup was taken. You cannot restore a table space to a different location on the same host or to a different host. ◆ Restores of table spaces that have been dropped are not supported. DB2 partition restore and recovery Avamar Plug-in for DB2 supports database partition restores in configurations which use the DPF. Unlike the backup process, which must run only from the catalog partition, the restore operation runs on each partition. ◆ To restore partitions from the catalog partition, you perform a restore to the original location. ◆ To restore partitions from non-catalog partitions, you perform a restore to a different location. “Restoring table spaces in a DB2 DPF environment” on page 76 provides more information. You must use the rollforward command to manually roll the table space forward after you restore a table space in a DPF environment. You roll a database forward only from the catalog partition. DB2 does not support rollforward operations from non-catalog partitions. 20 EMC Avamar 6.1 for IBM DB2 User Guide CHAPTER 2 Installation This chapter describe how to install and configure the Avamar Plug-in for DB2.

The plug-in options that are available depend on the operation type and client plug-in type. You specify plug-in options when you perform on-demand backup or restore operations, or when you create a dataset for a scheduled backup. You set plug-in options in Avamar Administrator with the graphical user interface (GUI) controls (text boxes, checkboxes, radio buttons, and so forth). In addition to using the GUI controls, you can type an option and its value in the Enter Attribute and Enter Attribute Value fields, which are used for special circumstances. “How to specify options” on page 100 provides more information. The Avamar software does not check or validate the information you type in the Enter Attribute and Enter Attribute Value fields. In addition, the values in the Enter Attribute and Enter Attribute Value fields override settings that you specify with the GUI controls. Detailed instructions on how to access and set plug-in options during a backup or restore are available in Chapter 3, “Backup,” and Chapter 4, “Restore and Recovery.” Backup options The following table lists the plug-in options for the Avamar plug-in for IBM DB2. Use these options when you perform an on-demand backup or when you configure a dataset for scheduled backups.

APPENDIX B Command-Line Interface This appendix describes how to use the command-line interface (CLI) to back up or restore DB2 database files. Topics in this appendix include: ◆ ◆ ◆ Overview................................................................................................................. 90 Command reference ................................................................................................ 92 CLI example commands .......................................................................................... 97 Command-Line Interface 89 Command-Line Interface Overview The Avamar Plug-in for DB2 provides a command line interface from which you can back up or restore DB2 database files by using the avdb2 command. You can use the CLI from all operating systems that the Avamar Plug-in for DB2 supports. The avdb2 command, which is available as a binary or executable, is located in the installation directory on the specific platform. ◆ For AIX and Linux platforms, the avdb2 binary is located in /usr/local/avamar. ◆ For a Windows platform, the avdb2 executable is located in C:\Program Files\avs\bin. You run the avdb2 command from a command shell on AIX or Linux platforms, or from the Command Prompt window on a Windows platform. Available operations The avdb2 command works with three main functions, which are referred to as operations: browse, backup, and restore. You specify an operation with the avdb2 command by using the --operation option. Browse The browse operation returns a list of client data available for backup. The CLI displays the list as formatted text or as XML text. The format depends on the value you specify for the --format option. Backup The backup operation backs up DB2 data to the Avamar server or a Data Domain system. You can specify plug-in options for the backup. Many of these plug-in options are the same options that you specify from Avamar Administrator in the Backup Command Line Options dialog box or on the Options tab when you create a dataset. Restore The restore operation restores DB2 data to the original location or to a different location. You can restore entire databases or single table spaces. You can specify plug-in options for the restore. These plug-in options are similar to the options you specify from Avamar Administrator in the Restore Command Line Options dialog box. Options There are three ways to specify options for the avdb2 command: ◆ Type the individual options on the command line. ◆ Use the avdb2.cmd file to specify options. For example, type each option on its own line in the avdb2cmd file: --online --db2-inst-user=db2inst1 ◆ 90 Create an option file as a text file, and then specify the option file on the command line using the --flagfile=FILE option, where FILE is the full path and file name of the option file. EMC Avamar 6.1 for IBM DB2 User Guide Command-Line Interface Help To display help content for all operations and options, type: avdb2 --help To display help content for a specific operation, type: avdb2 --help --operation=OPERATION where OPERATION is browse, backup, or restore. DB2 instance password security on AIX and Linux All backup and restore operations require you to specify the DB2 instance user name and password by using the --db2_inst_user and --inst-admin-password options. You can specify these options directly on the command line or in the avdb2.cmd file. When you specify the --db2_inst_user and --inst-admin-password options on the command line on AIX and Linux platforms, the user name and password appear as plain text to other users who are logged in to the system. For example, a user can use the ps -eaf command to view process status information for avdb2. The following output illustrates the information that a user can see when you specify the --db2_inst_user and --inst-admin-password options on the command line: # ps -eaf|grep avdb2 root 21569 15301 3 10:43 pts/3 00:00:00 ./avdb2 --sysdir=/usr/local/avamar/etc --operation=backup --id=guest@/clients/db2-client.example.com --password=guest123 --server=avamar1.example.emc --acnt=/clients/db2-client.example.com --db2_inst_user=db2inst1 --inst_admin_password=iso*help db2inst1/AVAMAR1 To prevent users on AIX and Linux from seeing DB2 instance user name and password information, specify the --db2_inst_user and --inst-admin-password options in the avdb2.cmd file: 1. Log in to the DB2 server as root. 2. Open the avdb2.cmd file in a text editor and add the --db2_inst_user and --inst-admin-password options by typing: --[avdb2]db2_inst_user=USERNAME --[avdb2]inst_admin_password=PASSWORD where: • USERNAME is the DB2 instance owner’s user name. • PASSWORD is the password for the DB2 instance owner’s password. 3. Save the changes to the avdb2.cmd file and close the text editor. 4. Change the permission on avdb2.cmd to root by typing: chmod 600 avdb2.cmd This chmod 600 command allows only the root user read and write access to the avdb2.cmd file. Overview 91 Command-Line Interface The following output illustrates the information that a user can see when the --db2_inst_user and --inst-admin-password options are specified in the avdb2.cmd file: # ps -eaf|grep avdb2 root 22255 15301 10 10:49 pts/3 00:00:00 ./avdb2 --sysdir=/usr/local/avamar/etc --operation=backup --id=guest@/clients/db2-client.example.com --password=guest123 --server=aiqferrari.bgl.avamar.emc --acnt=/clients/db2-client.example.com db2inst1/AVAMAR1 The user name and password visibility problem does not apply to the Windows operating system.

Troubleshooting 100 102 103 103 105 105 99 Troubleshooting How to specify options To resolve certain backup or restore problems may require the use of special options that you must type in the Enter Attribute and Enter Attribute Value fields. These fields are available by clicking the More button in the Backup Command Line Options or the Restore Command Line Options dialog box. The following procedure explains how to specify options from either dialog box. The procedure uses the Backup Command Line Options dialog box, however, the same steps apply to the Restore Command Line Options dialog box. The Avamar software does not validate the text you type in the Enter Attribute and Enter Attribute Value fields. Ensure that you enter the options and values correctly. To specify options: 1. From the Backup Command Line Options or the Restore Command Line Options dialog box, click the More button. The dialog box expands to display the Enter Attribute and Enter Attribute Value fields. 2. Type the option name in the Enter Attribute field and the value for the option in the Enter Attribute Value field. The following figure shows the dialog box after you type values in the Enter Attribute and Enter Attribute Value fields. 3. Click . The option and value appear in the area below the Enter Attribute and Enter Attribute Value fields. 4. To add more options for the backup or restore operation, repeat steps 2 and 3. 100 EMC Avamar 6.1 for IBM DB2 User Guide Troubleshooting The following figure shows the dialog box after adding two options. Additional information for on-demand backup and restore operations is available in Chapter 3, “Backup,” and Chapter 4, “Restore and Recovery.” How to specify options 101 Troubleshooting Backup or restore fails with a “Failed to create backup of db” error A backup or restore operation fails with an error message similar to the following: snapup: Failed to create backup of db /. db2 errcode -2025 This error message sometimes indicates that the avtar process timed out during the DB2 backup or restore initialization process. A restore of a dropped database, for example, may fail intermittently because the avtar process timed out. To resolve this problem, increase the avdb2-stream-timeoutsecs option from the 30 seconds (default setting) to 60 seconds or more. Specifying the avdb2-stream-timeoutsecs option To set the avdb2-stream-timeoutsecs option for a backup or restore: 1. Set up the backup or restore by using the correct procedure and steps in Chapter 3, “Backup,” or Chapter 4, “Restore and Recovery.” 2. Set the --[avdb2]avdb2-stream-timeoutsecs option and value for the backup as described in “How to specify options” on page 100. 3. In the Enter Attribute field, type --[avdb2]avdb2-stream-timeoutsecs. 4. In the Enter Attribute Value field, type 60 or more seconds. The following figure shows the Backup Command Line Options dialog box after adding the --[avdb2]avdb2-stream-timeoutsecs option and a value of 120 seconds. 102 EMC Avamar 6.1 for IBM DB2 User Guide Troubleshooting 5. Complete the remaining backup or restore steps as described in Chapter 3, “Backup,” or Chapter 4, “Restore and Recovery.” Backup fails with socket timeout errors If a backup fails with a socket timeout error, set the value for the --[avdb2]avdb2-stream-timeoutsecs option as described in “Specifying the avdb2-stream-timeoutsecs option” on page 102. Granular browse fails to display table spaces In an active/active DPF environment, the Browse for Granular Restore option fails to display table spaces from an offline backup and returns an error message similar to the following: The backups are taken prior to enabling the database for recovery This problem occurs even when you have enabled the database for recovery. To resolve this problem, specify the --[avdb2]avdb2-stream-delayclosesecs option with the offline backup. After the backup completes, verify that the Browse for Granular Restore option displays table spaces for the selected backup. For example, to set the --[avdb2]avdb2-stream-delayclosesecs option: 1. Complete the correct backup procedure in Chapter 3, “Backup” up to the step where you set options in the Backup Command Line Options dialog box. 2. In the Backup Command Line Options dialog box, set the --[avdb2]avdb2-stream-delayclosesecs option and value for the backup as described in “How to specify options” on page 100. 3. In the Enter Attribute field, type --[avdb2]avdb2-stream-delayclosesecs. 4. In the Enter Attribute Value field, type a value from 5 to 15. The value represents milliseconds. The default is 2 milliseconds. Backup fails with socket timeout errors 103 Troubleshooting The following figure shows the Backup Command Line Options dialog box after adding the --[avdb2]avdb2-stream-delayclosesecs option and a value of 5. 5. Complete the remaining backup steps. Chapter 3, “Backup,” provides more information. 6. After the backup successfully completes, verify that the Browse for Granular Restore option correctly displays table spaces for the backup: a. From the Backup and Restore window, click the Select for Restore tab. b. Select the date of the backup from the calendar. c. Select the offline backup you created in steps1–5 from the list of backups. d. Click (the Browse for Granular Restore button). The Destination Client Selection dialog box appears. e. Leave Restore everything to its original location selected and click OK. f. Expand the folders in the directory tree to view table spaces available for restore. 104 EMC Avamar 6.1 for IBM DB2 User Guide Troubleshooting Avamar Administrator shows the SYSCATSPACE and USERSPACE1 table spaces in the following sample figure. This ability to view table spaces confirms that the Browse for Granular Restore option is working as designed. Restore fails with a “Failed to initiate the restore operation” error A restore operation fails and writes the following error to the log file: Failed to initiate the restore operation To resolve this problem: 1. Set the --[avdb2]subprocesstimeoutsecs option and value for the restore operation as described in “How to specify options” on page 100. 2. In the Enter Attribute field, type --[avdb2]subprocesstimeoutsecs. 3. In the Enter Attribute Value field, type a value from 40 to 60. The default value is 30 seconds. 4. Retry the restore operation. Unable to connect to database during backup A backup fails with an error message similar to the following when the OS locale is set to Chinese: 2013-09-14 00:15:19 avdb2 Warning <12740>: Unable to connect to database [DBYMZ] due to sql connection failure, error : [-1]. Restore fails with a “Failed to initiate the restore operation” error 105 Troubleshooting 2013-09-14 00:15:19 avdb2 Warning <15301>: DB2 returned message [ [IBM][CLI Driver] SQL0332N Character conversion from the source code page "1392" to the target code page "UNKNOWN" is not supported. SQLSTATE=57017], SQLCODE [-332] This error occurs for backups performed by using Avamar Administrator or the avdb2 command from command-line interface. The Avamar Plug-in for DB2 does not support I18N. Only ASCII environments are supported. 106 EMC Avamar 6.1 for IBM DB2 User Guide GLOSSARY This glossary provides definitions for terms used in this guide. A activation administrator archive logs See “client activation.” The person who normally installs, configures, and maintains software on network computers, and who adds users and defines user privileges. Files that are used by DB2 for roll forward recovery. Avamar Administrator A graphical management console software application, which remotely administers an Avamar system from a supported Windows or client computer. Avamar client A computer or workstation that runs Avamar software and accesses the Avamar server over a network connection. Avamar client software comprises a client agent and one or more plug-ins. Avamar server The server component of the Avamar client/server system. An Avamar server is a fault-tolerant, high-availability system that efficiently stores the backups from all protected clients. It also provides essential processes and services required for data restores, client access, and remote system administration. An Avamar server runs as a distributed application across multiple networked storage nodes. B backup A point-in-time copy of client data that can be restored as individual files, selected directories, or as entire file systems. Although more efficient than a conventional incremental backup, a backup is always a full copy of client data that can be restored immediately from an Avamar server. C client activation client agent client registration cold backup The process of passing the client ID (CID) back to the client, where it is stored in an encrypted file on the client file system. A platform-specific software process that runs on the client and communicates with the “Management Console Server (MCS)” and with any plug-ins installed on that client. The process of establishing an identity with the Avamar server. When Avamar recognizes the client, it assigns a unique client ID (CID), which it passes back to the client during activation. A backup performed while the database is offline. EMC Avamar 6.1 for IBM DB2 User Guide 107 Glossary D Data Domain system Data Partition feature database database partition dataset DB2 instance Disk-based deduplication appliances and gateways that provide data protection and disaster recovery (DR) in the enterprise environment. A feature that enables the distribution of a DB2 UDB database across multiple servers in a cluster or multiple nodes on massively parallel processors (MPP). A DB2 database can be distributed in several database partitions. A collection of data arranged for ease and speed of update, search, and retrieval by computer software. An independent part of a partitioned database with its own data, configuration files, indexes, and transaction logs. A policy that defines a set of files, directories, and file systems to include or exclude from a backup. A dataset is a persistent and reusable Avamar policy that can be named and attached to multiple groups. An independent environment where database objects can be created and applications can be run against them. DD Boost The API that Avamar clients use to access a Data Domain system. The DD Boost API is installed automatically on the client computer when you install the Avamar client. It is also installed automatically on the Avamar server when you install Avamar. disaster recovery Recovery from any disruptive situation, such as hardware failure or software corruption, in which ordinary data recovery procedures are not sufficient to restore a system and its data to normal day-to-day operations. DNS domain Domain Name Server. A dynamic and distributed directory service for assigning domain names to specific IP addresses. A feature in Avamar Administrator that organizes large numbers of clients into named areas of control and management. F file system A software interface used to save, retrieve, and manage files on storage media by providing directory structures, data transfer methods, and file association. G granular recovery 108 An Avamar feature that enables you to restore a part of a backup rather than the entire backup. The Avamar Plug-in for DB2 enables you to restore table spaces from a backup. group A level of organization in Avamar Administrator for one or more Avamar clients. All clients in an Avamar group use the same group policies, which include the dataset, backup schedule, and retention policy. group policy The dataset, schedule, and backup retention policy attached to a group that is used by all clients in a group, unless these policy settings are overridden by an administrator at the client level. EMC Avamar 6.1 for IBM DB2 User Guide Glossary H hot backup A backup that is performed while users are online and have access to the data that is being backed up. L LAN Local Area Network. M Management Console Server (MCS) metadata The MCS provides centralized administration (scheduling, monitoring, and management) for the Avamar server. The MCS also runs the server-side processes used by the Avamar Administrator graphical management console. Hash information that identifies stored sub-file information for deduplication, and is required to revert deduplicated client backup data to the regular non-deduplicated format. P plug-in policy An Avamar plug-in is a software process that recognizes a particular kind of data on that client. A set of rules for client backups that can be named and applied to multiple groups. Groups have dataset, schedule, and retention policies. R recover redirected restore registration restore retention roll forward To restore data from a backup to a client disk and apply transaction logs to the data to make it consistent with a given point in time. The process of restoring backed up data to a location other than to its original location. See “client registration.” A file or object restore. An operation that retrieves one or more file systems, directories, files, or data objects from a backup and writes the data to a designated location. The ability to control the length of time that backups are kept in an Avamar server before automated deletion. Retention can be set to permanent for backups that should not be deleted from an Avamar server. Retention is a persistent and reusable Avamar policy that can be named and attached to multiple groups. The process of updating a database or table space by applying changes recorded in database log files. A roll forward is performed after you restore a database backup. S schedule The ability to control the frequency and the start and end time each day for backups of clients in a group. A schedule is a persistent and reusable Avamar policy that can be named and attached to multiple groups. EMC Avamar 6.1 for IBM DB2 User Guide 109 Glossary T table space transaction logs 110 Containers within a database that store specific data. DB2 includes five table spaces, which are named according to their usage: catalog, regular, large, system temporary, and user temporary. IBM DB2 documentation provides more information. A set of files that provides a history of updates made to a database. You can use transaction logs to roll back a database to a previous state.
