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 Document: Tivoli Storage Manager Deduplication Sample Architecture Date: 09/28/2012 Version: 1.0 Page 20 of 21
