BACK UP AND PROTECT THE LIBRARY METADATA
Toensuretheavailabilityofyourlibraryandencrypteddata,protect
librarymetadatabyfollowingtheproceduresdescribedinthissection.
Librarymetadataincludeslibraryconfigurationdata,theMLMandDLM
databases,andallBlueScaleencryptionkey‐relateddata.
Note: TheDLMdatabaseisincludedinanyoperationsthatbackupor
restoretheMLMdatabase.
Important
The automatic weekly auto-save file reflects the state of the MLM database at the
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
Back Up the MLM and DLM
Databases on page 316 when you are finished to ensure that you have a backup
that accurately reflects the information in the database.
