33 Setting Up the Dell™ DR Series System as a CIFS Backup Target on EMC Networker | February 2014
5 Set 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 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 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 six hours per week when backups are not taking place, and generally
after a backup job has completed.
