•
Configuration information for a Virtual Volume will only be copied if its root is in the
backup/copy path.
•
Incremental backups and copies, including replication copies, transfer updates of a
Virtual Volume if the backup/copy path includes the Virtual Volume root. However,
copies and recoveries will not delete Virtual Volumes.
Note:
With an Incremental Block-Level Replication (IBR) license these
updates can be done as block-level ADC updates.
•
If a recovery or copy is merging its contents into an existing Virtual Volume then the
Virtual Volume information will also be merged. If a Virtual Volume is recovered/copied
to an existing non-empty directory that is not part of the same Virtual Volume, then the
existing on-disk settings will be kept.
Clearing the Backup History or Device Mappings
To clear the records of old backups that have been made, use the Web Manager. During
incremental backups, Titan uses the records of old backups to determine the date and time
after which it must back up modified files. If a backup has been lost, clear the records to force a
full backup to occur instead of an incremental backup.
Also, the mappings between the tape library devices on the Fibre Channel (FC) and the names of
the tape drives and autochangers given in the storage management application can be cleared.
When a tape library device is attached to the FC, the device is assigned a number. The number
becomes part of the device name. Adding more devices to the FC will not cause the device names
to change. When replacing an existing tape library with a new one and keeping the original
device names for the new devices, the device mappings must be cleared and then the devices
must be re-added in the desired order.
