7 Housekeeping function The Housekeeping page: • Contains four tabs that display housekeeping statistics and graphs, see The Housekeeping page (page 105) • Allows administrators to configure housekeeping blackout windows, see Configuring blackout windows (page 107) • Allows administrators to pause housekeeping, see Pausing housekeeping (page 107) NOTE: With the current version of the software there are no equivalent CLI commands available for the tasks described in this section. The Housekeeping page Select Housekeeping from the HP StoreOnce menu item to display current housekeeping activity as two graphs: Load and Jobs. There are four tabs that display housekeeping statistics for: Overall, Libraries, Shares and StoreOnce Catalyst. Once on the Housekeeping page users with an Admin login can also configure blackout windows for housekeeping. IMPORTANT: Housekeeping is an important process in order to maximize the deduplication efficiency of the appliance and, as such, it is important to ensure that it has enough time to complete. Running backup, restore, replication and Catalyst Store operations with no break (i.e. 24 hours a day) will result in housekeeping never being able to complete. This is a complex subject. We strongly recommend that you read Best Practices for VTL, NAS, StoreOnce Catalyst and Replication implementations that is available on http:www.hp.com/support/manuals for more detailed guidance. Housekeeping graph Housekeeping graphs can be displayed as a total across all devices by selecting the Overall tab. Alternatively, the housekeeping graphs for individual device types can be shown by selecting one of the three device types tabs, and then selecting a particular device within that type. This allows you to display housekeeping information for a particular Virtual Tape Library, NAS share or Catalyst Store. Select the required tab to display the Load and Jobs graphs. • Load: shows you the outstanding number of housekeeping jobs (sampled on an hourly basis). If within each hourly sample period all jobs are being processed, this graph will show very little load (almost zero). If this graph shows a flat or increasing trend, it is indicating that the StoreOnce Backup system is falling behind, and more time should be allocated to perform housekeeping tasks. • Jobs: show the number of new housekeeping jobs that have been received and the number of housekeeping jobs processed within hourly sampling periods This view complements the The Housekeeping page 105

Housekeeping graph
Housekeeping graphs can be displayed as a total across all devices by selecting the
Overall
tab.
Alternatively, the housekeeping graphs for individual device types can be shown by selecting one
of the three device types tabs, and then selecting a particular device within that type. This allows
you to display housekeeping information for a particular Virtual Tape Library, NAS share or Catalyst
Store.
Select the required tab to display the Load and Jobs graphs.
•
Load:
shows you the outstanding number of housekeeping jobs (sampled on an hourly basis).
If within each hourly sample period all jobs are being processed, this graph will show very
little load (almost zero). If this graph shows a flat or increasing trend, it is indicating that the
StoreOnce Backup system is falling behind, and more time should be allocated to perform
housekeeping tasks.
•
Jobs:
show the number of new housekeeping jobs that have been received and the number
of housekeeping jobs processed within hourly sampling periods This view complements the
