What is HP StoreOnce Catalyst
HP StoreOnce Catalyst is a feature that allows:
•
Backup applications to back up data to a target store on the HP StoreOnce Backup System.
Deduplication may occur on the media server or on the HP StoreOnce Backup System.
•
Backup applications to copy jobs between HP StoreOnce Backup Systems. All configuration
is carried out from the backup application, which makes this an attractive alternative to using
the replication function on the HP StoreOnce Backup System.
To use this feature you require a backup application that supports HP StoreOnce Catalyst. Refer

for up-to-date details on supported applications.
Benefits of HP StoreOnce Catalyst
•
The backup application is in full control of its data for the full lifecycle of the backup data
•
The backup application has full visibility of all items and jobs on the HP StoreOnce Backup
System
•
Deduplication can occur on either the media server or HP StoreOnce Backup System, which
ensures efficient use of the available bandwidth
•
There is no limiting geometry, such as cartridges for VTL libraries
•
There is no enforced limit on the number of items within a store
•
Copy jobs are instigated from the application and have none of the complexities of replication
mapping

StoreOnce Catalyst Optimized Backups:
one of the main advantages of HP StoreOnce Catalyst
is that deduplication may occur on either the media server or the HP StoreOnce Backup System.
If deduplication occurs on the media server so that only unique data is sent to the HP StoreOnce
Backup System, a low bandwidth network link is adequate. If the media server sends all the
data and deduplication is carried out on the HP StoreOnce Backup System, a high bandwidth
network link is required. The combined CPU power of multiple media servers and the reduced
