T
Tape Attach If you attach a supported, physical tape library or tape drive directly to your G1 HP StoreOnce
Backup System, you will be able to copy or export data to the physical tape library or tape drive
so that backups can be stored offsite. This is an important requirement for Disaster Recovery
strategies. The main difference between copy and export is that copied data remains on the G1
HP D2D Backup System; exported data is removed from it, but can be imported easily when
required. These functions are grouped under the Tape Attach section of the Web Interface.
G2 HP StoreOnce Backup Systems do not support direct export to tape.
Tape rotation
strategies
Tape rotation strategies determine when backups are run, the number of cartridges that are
required and how they are reused. Virtual Tape Library targets on an HP StoreOnce Backup
System can easily be incorporated into most tape rotation strategies. If your organization does
not yet have a tape rotation strategy in place, see the HP StoreOnce Backup System Concepts
Guide for example configurations.
V
Virtual Tape
Devices
Virtual Tape Devices are backup targets on the HP StoreOnce Backup System to which the backup
application on the hosts write data. They appear to the host as network-attached or locally-attached
physical tape library or autoloader, but physically, they use disk space on the HP StoreOnce
Backup System which, as in tape terminology, is referred to as slots or cartridges.
