An inventory for your backup drives

The 3-2-1 rule is easy to say and hard to track: three copies, two media, one off-site. When a drive dies, the question is not “do we have a backup?” but “which drive is it and where?”

What to record for every backup drive

Pair masters and backups

Name them as pairs (see naming conventions) and add a note on each pointing to the other. Search either ID and you find both.

Track drive health

Where’s My Drive lets you set a health status per drive — Good, Watch, Problem — with a comment like “SMART warnings, replace soon”. It shows on the drive for everyone who scans it.

Organised backup drives on a shelf

Verify, don’t assume

Rescan backups after each backup run. If the backup’s file count or size is far from the master’s, you know before you need it.

🏷️

Drives in cold storage? Use durable labels — direct thermal ones can fade. See thermal vs thermal transfer labels.

Catalog all three. When a drive fails, one search for 042 shows every copy, where it lives and when it was last updated.

When a drive starts failing

  1. Set its health to Problem with a note (“clicking on spin-up, SMART warnings”) so nobody grabs it for a new job.
  2. Search its ID to find the backups and check their last scan dates.
  3. Copy from the most recent backup to a new drive, scan the new drive, and give it the old drive’s ID in the note so the history carries over.
  4. Move the failed drive to Trash in the catalog (restorable if you need to look back).

Drives in cold storage should still be spun up and rescanned occasionally — a backup nobody has checked is only a hope.
