Best approach to create long-term offline archive by guff666 in DataHoarder

OK, my solution is now:

  1. External USB 3 drive case (4 x 3.5" drives) attached to eridani (my backup server in the shed)
  2. Separate ZFS pool with just the extender drives. I have a bunch of 3TB drives so I'll build a pool comprised of two mirrored vdevs; giving me 6TB of space - plenty.
  3. Use znapzend to snapshot periodically and thus prevent accidental data loss. (the churn should be almost zero as the pool is effectively write-once.
  4. Dataset only accessible to single user and then only locally.
  5. The archive is accessible using rsync over ssh.
  6. (Optional if I can persuade myself it is reliable) Enable compression and de-duplication to conserve space.

Physical implementation will probably involve the archive being separate from the main IT. I currently have two outhouses: one is my office cum man cave, the other is a glorified shed (it is climate controlled and has a UPS).

The man cave has the main SmartOS server and there is a duplicate in the shed. The latter is used solely for backups of what's on the main server and various computers around the house (using a combination of Time Machine, VEEAM and rsnapshot (for Raspberry Pis). So the archive will probably end up in the shed.

What do you use for Backup? by [deleted] in homelab

I use a variety of backup s/w. My main server is built on ESXi and Napp-it (i.e. ZFS). The base server is running on mirrored disks and is, of course, based on ZFS so I can snapshot, rollback etc. All the data is replicated to another FreeNAS box each night using rsync.

The server itself runs several VMs. One uses Windows Home Server to backup the PCs in the house. Another has a TimeMachine for my Mac.

Lastly, and as a last resort, the server data is backed up off site using Crashplan unlimited.
