Add Management Class
Add a management class to an IBM Spectrum Protect server that is managed by the Operations Center.
A management class is a collection of backup, archive, and space management settings that define the requirements for protecting data.
Some backup and archive settings are specified in copy groups. Copy groups are not shown in the Operations Center but you can manage common policy settings by adding or editing management classes.
You can specify additional options by using the DEFINE COPYGROUP, UPDATE COPYGROUP, and UPDATE MGMTCLASS commands.
- Backup
- You can specify the following retention settings for backup files:
- TOC Destination
- The storage pool for table of contents (TOC) data.
TOC data is used for file-level restoration of NAS backup data and
client backup sets. The TOC destination is a primary storage pool
with the data format of NATIVE or NONBLOCK.Tip: To avoid mount delays, ensure that the TOC destination is a random-access storage pool (DISK device class), or a sequential-access storage pool for files on disk (FILE device type).
When you back up a NAS node or generate a client backup set, you specify whether an associated TOC is created. When a backup image or a client backup set has an associated TOC, you can examine and restore individual files or directories. To examine and restore files, you can use a web backup-archive client or the QUERY TOC and RESTORE NODE server commands.
- Keep extra versions for
- Specifies how long to retain a backup version after it becomes
inactive. A version of a file becomes inactive when the client stores
a more recent backup version, or when the client deletes the file
and then runs a full incremental backup.
If you select No limit, the server deletes backup versions based on the VEREXISTS and VERDELETED parameters of the UPDATE COPYGROUP command. By default, the Operations Center does not limit the maximum number of versions that are kept.
- Keep the last version for
- Specifies the number of days to retain the last backup version
of a file that has been deleted from the client.
If you select No limit, the server keeps the last remaining backup version forever, unless a user or administrator deletes the file from server storage.
- Migrate
- The following settings can be specified for IBM Spectrum Protect for Space Management clients:
- Technique
- Specifies whether files in the management class are eligible for hierarchical storage management
(HSM) migration.The following values are available:
- AUTOMATIC
- Files are eligible for both automatic migration and selective migration.
- SELECTIVE
- Files are eligible for selective migration only.
- NONE
- Files are not eligible for migration.
- Requires backup
- Specifies whether a backup version of a file must exist before the file can be migrated.
Tip: The migration settings do not affect backup-archive clients or application clients.
