HP StoreOnce Backup System Concepts and Configuration Guidelines (BB877-90913, November 2013)

• Ensure the backup clean-up scripts that regularly check for expired Catalyst Items run at a
frequency that avoids using excessive storage to hold expired backups (every 24 hours is
recommended).
• There are several specific tuning parameters dependent on backup application implementation
– please see separate document for more details..
StoreOnce Catalyst and the StoreOnce GUI
Refer to the HP StoreOnce Backup system user guide or online help for detailed information about
using the Catalyst functions on the StoreOnce GUI.
Maximum concurrent jobs and blackout windows
As with VTL and NAS replication, each StoreOnce appliance supports a maximum number of
concurrent jobs. In this case, the parameters are Outbound copy jobs and Data and Inbound Copy
jobs. Bear in mind that Catalyst stores can act as both inbound and outbound copies when used
in multi-hop mode. See Key parameters (page 115).
The concurrency settings for Catalyst are configured by selecting the StoreOnce Catalyst - Settings
tab and Edit.
