Re: [PLUG] Physically Secure Backup Disk

Seems to me one option would be to keep the disks that are in rotation but not currently in use in the fire safe. You’d lose your most recent data in case of a fire, but hopefully not the bulk of your data.

Another option beside the fire safe would be a safe deposit box at your local bank. This would give you offside backups without worrying about the data getting intercepted during transit. (Unless you’re mugged on the way to your bank.)

Of course with either option you could store important physical documents in there as well.

I use a large USB disk connected to a Raspberry Pi for backup.  The Pi runs a python script every night to call rsync and backup all my files.  I want to be sure this backup disk is secure in case I actually need the files on it.

The files are secure from being unreadable by making them unencrypted, uncompressed copies using NFS.  Also, I periodically swap the disk so I have a rotation of large disks.  Even if the disk fails, the next oldest is only a few months out of date.

I have made the disk secure from theft by hiding it in a remote corner of my basement.  Anybody who steals my computer equipment will most likely never find the PI and the backup disk.

But I'm worried about protecting it against fire.  I thought I might put the disk inside one of those inexpensive fire safes that people use for critical documents, but I have 2 concerns:

  1. Would the disk overheat in the small unventilated and insulated container?
  2. I'd have to drill a hole for the USB cable.  Would this negate the effectiveness of the "fireproof" box?

I'm talking about 8 terabytes of data, so online storage is not practical (and I'm too cheap to pay for it anyway)

I would appreciate suggestions.  TIA!
