Disaster Recovery Planning

As a part of best disaster recovery planning and practices, Spectra Logic
strongly recommends backing up the MLM database to a USB device or
emailing it to a preconfigured mail recipient automatically after using
MLM for some period of time. In the event of a disaster, you can use the
backup to restore the MLM database information for the media in your
library instead of rebuilding it by loading each cartridge into a drive (see
Restore the MLM and DLM Databases on page 350).
The automatic weekly auto-save file reflects the state of the MLM database at the
Important
time the backup was created. If MLM-enabled media is imported into or exported
from the library during the period between the automatic weekly auto-save
operations, the backup of the MLM database may not accurately reflect the library's
inventory.
If you plan to import or export a large number of MLM-enabled cartridges, back up
the MLM database using the procedure described in
Databases on page 284
that accurately reflects the information in the database.

Description
When a cartridge is exported from the library, an asterisk (*) next to
the barcode indicates that it is currently out of the library. However,
all of the MLM data for the cartridge is still available. Define the
frequency with which you export the complete MLM report and
make a note of all exported tapes.
When you save an MLM report (see Generate MLM Reports on
page 275), you can choose between saving all MLM data or just the
data from the most recently viewed report.
You can save a copy of the MLM report as a comma‐separated text
file (*.rpt) to a USB device, mail the saved report to previously
configured email recipient, or both. If desired, you can zip the file
before saving it (see Save an MLM Report on page 280).

database.
 For extra security, the library's Auto Configuration Save
feature automatically backs up its configuration and the MLM
and DLM databases to the LCM memory card once a week
and whenever a partition is created or modified (see Use
Automatic Backup of the Library Configuration on page 137).
 If email for the auto‐save backup is configured, the backups
are emailed to the designated recipient (see Enable Email for
the Auto Configuration Save File on page 109).
 See Back Up and Protect the Library Metadata on page 458
for additional disaster planning information.
