HP StoreOnce VSA Backup System User Guide (TC458-96025)

NOTE: After a power cycle, the start of housekeeping is delayed for 15 minutes. The graphs will
not recalculate during that time. As housekeeping resumes, the housekeeping queue is recalculated.
The queue will show the number of jobs increasing even if new jobs are not being created. If
housekeeping is paused (or in blackout), the queue will not display existing jobs until housekeeping
is re-enabled. However, new housekeeping jobs will be reported.
Configuring blackout windows
Scheduling housekeeping blackout windows to cover the period during which backups are occurring
can improve backup performance. Housekeeping windows apply across the whole appliance.
On the Blackout Windows tab, click Edit and enter the appropriate Start of Restriction and End of
Restriction times for each window. Verify the Apply First Time Restriction box is checked. This
ensures the times that are specified are enabled. If it is not checked, the times will be ignored.
Configure up to two windows for each day. Settings apply to all devices on the .
TIP: Ideally, housekeeping blackout windows should be set for those times when the HP StoreOnce
Backup system is running backup or replication or Catalyst copy. See the HP StoreOnce Concepts
and Configuration Guidelines for recommendations.
Pausing housekeeping
On the Blackout Windows tab, click Pause Housekeeping to pause the housekeeping process. This
setting applies to all devices, libraries, and shares on the HP StoreOnce Backup system. The pause
is not retained if the power fails or the HP StoreOnce Backup system is powered down.
