I have between 20-30 TB of data I want to keep a copy of in a firesafe. I do not want to use an online storage solution, I want to maintain my personal data at my home.
My current plan is to get (2) Mediasonic HFR2-SU3S2 PRORAID enclosures and (8) WD Red Pro NAS 16TB drives to fill them. The first would contain a full backup and be placed in the safe. The second would be attached to my machine and receive nightly backups. Periodically, I would rotate the enclosures, taking the one from the safe and swap it with the one connected to my machine.
Are there any problems with my plan that I am not thinking of? Are there better solutions?
Is anyone else keeping a rotating data backup in a safe? How is it working out for you?
Instead of a fire safe which will only offer some protection I would rather get two Pelican style cases. Keep your backup drive(s) in there. Use a deduplicating/encrypted backup software to create two backup sets (I highly recommend BorgBackup). Store one of the backup cases off-site (at a friend’s house, in a drawer at work, …) and occasionally rotate the two cases.
