Setting up the Dell DR Series System with IBM Tivoli Storage Manager

Setting up the DR Series system cleaner

Performing scheduled disk space reclamation operations are recommended as a method for recovering

disk space from system containers in which files were deleted as a result of deduplication.

The system cleaner runs during idle time. If your workflow does not have a sufficient amount of idle time

on a daily basis, then you should consider scheduling the cleaner to force it to run during a scheduled

time.

If necessary, you can perform the procedure shown in the following example screenshot to force the

cleaner to run. After all of the backup jobs are set up, the DR Series system cleaner can be scheduled. The

DR Series system cleaner should run at least 40 hours per week when backups are not taking place, and

generally after a backup job has completed.
