In its simplest form, I am looking to add offline/rotated backups to our 3-2-1 backup chain. I just want an offline copy as a final failsafe.
My thought is to get a server or NAS appliance with 2 x 15TB+ drives in a RAID1 which would act as a backup repository for ALL backups, and then have a 3rd drive with which to rotate out with one of the RAID1 pairs. Basically we'd pull out 1 drive and insert the free one and let the mirror complete and then swap it out again the next day, back and forth. This way, there would always be an air-gapped drive with a full copy of all our backups.
The only issues are mirror write-time for ~10TB and actually making sure the mirroring is automatic.
My company used to have a BNAS appliance from Highly Reliable which did just this, and it seemed to do an ok job, except mirror times were pretty long. This was 5+ years ago though.
Any ideas? I'm just trying to get the ideas flowing. I'm sure I could probably do a custom server build for something like this if I have to.
Whatever you do, mucking with the RAID is not what you want to be doing. That is something that would guarantee data loss due to someone entering a setting wrong.
I wouldn't call it mucking with RAID. Its just drive rotations.
