[kwlug-disc] Offline/offsite archival data storage

Myself, I bought two 3TB USB3 drives for $99 each. 3TB of cloud storage
would cost... more.

All my data rsync's to it automatically on Sunday. Monday morning I take it
with me to work, and bring the other drive home, and plug it in. Repeat
next week. I've always got my most recent backup stored offsite.

Once you get that working, you can add on other options, like encrypting
the drive, etc.

Only problem I've got to worry about is bit-rot on long-storage items (I'm
not using btrfs yet). Most of that data has been migrated to git-annex now,
which takes care of detecting and repairing that itself.
