Storeonce Catalyst Blackout Windows Tab - HP StoreOnce User Manual

StoreOnce Catalyst Blackout Windows tab

The two fields at the top of this tab show the System Time and whether a Blackout Window is
currently active. The information below displays the start and stop times of any blackout windows
that have been configured for outbound copy jobs.
Users with an Admin login may specify times when outbound copy jobs should not occur, for
example during planned maintenance or heavy network traffic. Multiple blackout windows may
be configured.
NOTE: Blackout windows are available on most StoreOnce functions, so that you can ensure
that all StoreOnce services run efficiently and do not compete for resources. For example, if you
are running backup, restore, replication and Catalyst Store operations with no break (i.e. 24 hours
a day), housekeeping will never be able to complete and performance will suffer. This is a complex
subject, see also Best Practices for VTL, NAS, StoreOnce Catalyst and Replication implementations:.
