4.4.5 Schedules and macro definitions to control server maintenance
tasks
The following section shows how to configure TSM to schedule data maintenance tasks to follow the best
practices of separating backup ingestion from data maintenance. The recommended ordering is explained
below, along with example of commands to implement these tasks through scheduling.
Here is the implemented sequence of tasks:
1. 00:00 - 07:00.
Client data ingestion.
2. 08:00 - 12:00.
Create the secondary disaster recovery (DR) copy using the BACKUP STGPOOL
command.
3. The following tasks can run in parallel:
a. 11:00 - 16:00.
Perform server-side duplicate identification by running the IDENTIFY
DUPLICATES command. This processes data that was not already deduplicated on the
clients.
b. 12:00 - 15:30.
Create a DR copy of the TSM database by running the BACKUP DATABASE
command. Following the completion of the database backup, the DELETE VOLHISTORY
command is used to remove older versions of database backups which are no longer
required. At completion of the backup, the volume history and device configuration are
backed up using the BACKUP VOLHISTORY and BACKUP DEVCONFIG commands.
4. 14:00 - 15:30.
Move data from the backuppool and archivepool random disk storage pools to the
tape storage pool using the MIGRATE STGPOOL command.
5. 18:30 - 23:00.
Reclaim unused space from storage pool volumes that has been released through
deduplication and inventory expiration using the RECLAIM STGPOOL command.
6. 22:00 - 04:00.
Remove objects that have exceeded their allowed retention using the EXPIRE
INVENTORY command.
4.4.5.1 Define scripts which run each required maintenance task
The following scripts are defined to perform the data maintenance tasks, and invoked via scheduled
administrative commands.
def script STGBACKUP "/* Run stg pool backups */"
upd script STGBACKUP "backup stg ARCHIVEPOOL copypool maxprocess=6
wait=yes" line=010
upd script STGBACKUP "backup stg BACKUPPOOL copypool maxprocess=6
wait=yes" line=020
upd script STGBACKUP "backup stg FILEPOOL copypool maxprocess=6
wait=yes" line=030
def script DEDUP "/* Run identify duplicate processes */"
upd script DEDUP "identify duplicates FILEPOOL numprocess=4 duration=360"
line=010
set dbrecovery TS3500DEVC numstreams=3
