HP Data Protector A.06.00 additional writers and HP StorageWorks Disk Array XP support for Microsoft Volume Shadow Copy Service integration

• Differential - similar as incremental backup, but the transaction logs are not
truncated. Requires Service Pack 1.
• Copy - a Full backup, but the logs are not truncated. This type of backup is not
intended for use in recovering failed systems.
Limitations
• A combination of VSS snapshot backups and non–VSS backups (for example,
incremental stream backups) is not supported.
• You can back up only the whole server or full storage groups. Single stores cannot
be backed up.
• Circular logging must be disabled; otherwise, only full backup recovery is possible.
• With Exchange Server 2003, only one VSS backup session can be running on
the same application system at once. With Exchange Server 2007, only one VSS
backup session backing up a specific storage group can be running on the same
application system at once. Consequently, if you start such a backup session
while another one is in progress, the latter waits until the first one finishes.
Rollforward recovery
Transaction logs must be backed up to be able to perform the rollforward operation.
Consistency check
A backup of the Microsoft Exchange Server database is considered as successful
only if the consistency check of the replicated datafiles succeeds. The consistency
check is enabled by default. To disable the consistency check, click on a created
backup specification, right-click Microsoft Exchange Writer in the Source tab, and
then click Additional options. In this page, you can also specify to throttle the
consistency check for a second after the specified number of input/output operations.
