If the tape barcode cannot be read, another
Tasks Need Interaction
window asks you to label a tape.
Actions on a tape library vault
If a tape library vault is selected on the
Navigation
pane of the console, the
Centralized vaults
page
toolbar will contain the following two actions that are used for tape libraries only:
Manage tapes
displays the
Tape Management
window allowing you to refresh information on
the library slots, inventory tapes in the slots, and define labels for the tapes. If you have a new
label assigned to the tape, the action enables you to eject the tape temporarily to make the same
label outside the cartridge.
Rescan tapes
displays the
Tape Rescanning
window, which is useful for selecting slots and
launching the Rescan (p. 144) procedure to read some special information on the content of the
specified tapes.
Also the
Edit
,
Delete
,
Validate
, and
Refresh
functions are allowed on a tape library vault.
It should be noted, these functions have some specific features for a tape library. So the
Edit
operation enables you to substitute a tape library device without the
Rescan
operation. The
Delete
operation clears all the information on the selected tape library vault from the storage node
database, i.e. the operation deletes the content data of all the tapes, when ever the data is used by
the storage node on the tape library device.
At the
Delete
operation, the vault content will be deleted from the storage node database without accessing
the tapes. The plans and tasks that use this vault will fail.
The backup archives, belonging to a deleting centralized vault on a tape library, will be deleted as well, but
these archives might be recovered by any storage node through the
Rescan
operation.
Actions with archives on tapes in a library
The following are common functions for archive data management for a backup archive selected in
the
Centralized vaults
view of the console, when the current vault is a tape library:
Validate
,
Delete
,
Delete all archives
. Deletion in the storage node database is performed without access to tapes. A
backup archive deleted from a tape library vault can be restored after the deletion by the Rescan (p.
144) operation, which is performed for all the tapes keeping the archive’s data.
The
Rescan
operation for a tape, where a backup was deleted from, can recover the backup, as it
recreates information on the content of the backup in the storage node database.
If all the backups are deleted from a tape, it is considered as free. So the deleted backups will be irrevocably lost
after the first writing to the tape.
Backing up to tape library
At creating a backup policy/plan with a tape library destination, you set up the backing up in the
same way as with other storage devices. The only difference is the additional Tape support (p. 118)
options that can be set up during the backup policy/plan creation. These options enable you to
specify how the created backup policy/plan should use tapes from the tape library, however the
options’ presets increase usage efficiency of both whole tape library and each tape.
To view and change the tape options, select
Options > Default backup and recovery options >
Default backup options > Tape support
from the top menu.
