Configuring blackout windows Scheduling housekeeping blackout windows to cover the period during which backups are occurring can significantly improve backup performance. Housekeeping windows apply across the whole service set. Click Edit and enter the appropriate Start of and End of Restriction times for each window. Make sure the Apply First Time Restriction box is checked. This ensures the times that have been specified are enabled. If it is not checked, the times are ignored. You may configure a maximum of two windows for each day. Settings apply to all devices on the appliance. TIP: Ideally, housekeeping blackout windows should be set for those times when the HP StoreOnce Backup system is running backup or replication. See the Best Practices for VTL, NAS, StoreOnce Catalyst and Replication implementations for recommendations. Pausing housekeeping Click Pause Housekeeping to pause housekeeping altogether (perhaps while you decide how best to configure blackout windows). This setting applies to all devices, libraries and shares on the HP StoreOnce Backup system. It is not retained if there is a power failure or the HP StoreOnce Backup system is powered down. Housekeeping should not be left in the paused state for significant amounts of time; use it only as a test tool. Configuring blackout windows 107
