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.
3. Click Apply.
Setting Recurrence for a Scheduled Event
To specify when and how often the event reoccurs:
1. On the Scheduler page, add or edit an event (see "Scheduler" on page 262).
2. In the Repeats drop-down box, select Does not repeat to disable recurrence. Or to
enable recurrence, select how often the event reoccurs:
Healthchecks and space reclamation must occur at least every seven days or once
a week.
l Daily - Specify the recurrence interval in days.
l Weekly - Specify the recurrence interval in weeks, and select the days the
event occurs on.
3. For recurring events, specify how long the recurrence continues (forever, for a certain
number of occurrences, or until a specific date).
For healthchecks and space reclamation, recurrence is always forever.
