Rescan
As stated above the storage node keeps information about tapes and their contents in a dedicated
database. The
Rescan
task reads information about the content of user-selected tapes and updates
the database.
The task can take a long-time so it is only initiated manually. You should select each slot with a tape
you want to rescan before the task launch.
Run the
Rescan
task:
for tapes that are unknown for the storage node
if the storage node database is lost or damaged
for tapes whose content is out of date (for example, a tape content was modified through
another storage node or manually).
Bear in mind, a tape might keep some backups that were deleted before the tape rescanning. So
after the task is completed, all such backups will be recovered in the storage node database and
become accessible for data recovery.
At rescanning a tape label should be saved in the storage node database. If a slot, selected for the
procedure, contains a tape that still does not have a label, the
Rescan
task for the tape is paused to
perform the Labeling (p. 139) procedure.
Labeling
When a tape required for data recovery is not found, the
Task Need Interaction
window will ask the
user to bring the tape and insert it into a tape library slot. So, all the tape cartridges need a barcode
or other readable labels.
If a tape does not get a label, you should define it before the tape will be used.
If you need to apply a specific label for a tape (for example, “MyWork” label for a tape dedicated to
back up files from the folder C:\work) instead of a barcode label, use the
Labeling
procedure as well.
To launch the procedure, select the tape library vault in the
Navigation
pane of the console, and click
Manage tapes
on the toolbar. Then the
Tape Management
window will show a list of the library
slots that contain tapes. For every tape belonging to the
Free
pool or to the
Acronis
pool, the slot
data field indicates the tape label. Labels are also displayed for tapes that are in the
Imported
pool
and contain backups written by Acronis (such might be the case when you bring a tape from another
tape library).
By default, an unused tape with a barcode gets a label that is equal to the barcode. If a barcode is
absent or corrupted, the label name will be created automatically. You can accept proposed labels or
provide your own label as a plain text.
Tapes from the
Free
or the
Imported
pool can be renamed on condition that the user account used
to run the storage node service (
ASN User
) has write permissions for these pools. These permissions
are not assigned to
ASN User
during installation, so you might need to add them manually.
To define your own label for a tape, select a related data field, type in a new label, click
Eject tape
,
write the same label on the tape cartridge (to make association with the label) and insert it back into
the same slot.
Once all the required tape labels are specified press
Set labels
to store labels in the storage node
database.
