• 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 terminology • StoreOnce Catalyst: the name of the StoreOnce function • StoreOnce Catalyst stores: the targets/device types in which backups are stored on the HP StoreOnce Backup system • StoreOnce Catalyst items: the items stored in the StoreOnce Catalyst stores on the HP StoreOnce Backup system • StoreOnce Catalyst clients: the generic term for applications that connect using the StoreOnce Catalyst interface • Data jobs: any backup or restore job • 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 network traffic means that it is often faster to deduplicate on the media server. However, actual performance varies depending upon the data and disk I/O speeds. • Copy jobs: these allow backup applications to create true copies of the data and not mirror images. The backup application specifies the store on the source StoreOnce Backup system for the outbound copy job and a target store on the destination StoreOnce Backup system for the inbound copy job. Once copied, the two versions are independent of each other; on either the source or destination StoreOnce Backup system data may subsequently be deleted, moved or added to, as required, from the backup application. • StoreOnce Catalyst Optimized Copy: all copy jobs are optimized. This means that the copy job is completed in a bandwidth-efficient manner. The two stores negotiate so that only unique data is transferred.

StoreOnce Catalyst terminology
•
StoreOnce Catalyst
: the name of the StoreOnce function
•
StoreOnce Catalyst stores
: the targets/device types in which backups are stored on the HP
StoreOnce Backup system
•
StoreOnce Catalyst items
: the items stored in the StoreOnce Catalyst stores on the HP StoreOnce
Backup system
•
StoreOnce Catalyst clients
: the generic term for applications that connect using the StoreOnce
Catalyst interface
•
Data jobs:
any backup or restore job
•
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
network traffic means that it is often faster to deduplicate on the media server. However, actual
performance varies depending upon the data and disk I/O speeds.
•
Copy jobs:
these allow backup applications to create true copies of the data and not mirror
images. The backup application specifies the store on the source StoreOnce Backup system
for the outbound copy job and a target store on the destination StoreOnce Backup system for
the inbound copy job. Once copied, the two versions are independent of each other; on either
the source or destination StoreOnce Backup system data may subsequently be deleted, moved
or added to, as required, from the backup application.
•
StoreOnce Catalyst Optimized Copy:
all copy jobs are optimized. This means that the copy
job is completed in a bandwidth-efficient manner. The two stores negotiate so that only unique
data is transferred.
