10.7 Scheduler
Scheduling Space Reclamation
During space reclamation, the ETERNUS CS800 deletes unneeded tags from the blockpool
to free up disk space. Schedule space reclamation regularly to make sure there is enough
disk space to store data.
CAUTION!
Because space reclamation can affect system performance, avoid running space
reclamation during known backup periods.
For more information about space reclamation, see "Space Reclamation" on page
423 .
To configure a schedule for space reclamation:
1. On the Scheduler page, add or edit an event in the Space Reclamation row (see
"Scheduler" on page 262 ).
2. Specify when and how often the event reoccurs (see "Scheduler" on page 262 ).
CAUTION!
For correct system operation, space reclamation must be run at regular intervals
(at least once a week).You can schedule space reclamation to occur daily or
weekly but not monthly or yearly. Also, recurrence is required.
