Managing disk archive media

These procedures assume that the archive device has been properly installed and is attached to the backup system so that the media is accessible for archiving. Once this is done, you can use the archive media subsystem to perform the following:

ClosedTo add a drive to a multi-drive system

For multi-drive systems, archives are written across all available drives. It is important to keep this in mind when defining your archive strategy. If your archive set grows and you need to use additional drives, do one of the following:

• Add one or more new drives to the existing set and prepare them as described in Preparing archive media. Preparing the drives creates a new logical volume but purges all data from the original drives. For example, you had been archiving to two drives. You add a third drive and prepare it. Subsequent archives are written across all three drives, but older archives that had been stored on the original two drives were deleted during the prepare operation.
• Remove existing drives to retain archived data, then insert a new set of drives and prepare. For details, see Removing archive drives for off-site storage and Preparing archive media.
ClosedRemoving archive drives for off-site storage

Use the procedures described in this section to remove drives for off-site storage. Before removing a drive, you must unmount it.

See the following topics for instructions:

ClosedTo unmount an archive drive

An archive must be unmounted before it is removed from an appliance for offsite storage.

1 Select Archive > Media. Connected media display in the Archive Media area.
2 Select the desired drive.
3 Click Unmount at the bottom of the screen.

The color of the disk icon changes to red to indicate that the drive is no longer mounted.

ClosedTo remove archive drives for off-site storage

For multi-drive systems, archives are striped across all drives in the set, so be sure to store them together as all drives are needed to restore any archived data.

1 Verify that media is not mounted. See To unmount an archive drive for details.

Warning!      Pulling mounted drives can result in data loss and corruption.

2 Pull the drive and be sure it is labeled for easy identification.
