Using ZFS to Achieve 3-2-1 Backups and Bitrot Protection on Limited Hardware
Presented By: Sean Twiehaus
I'm gearing this talk towards homelab users. The premise will be: I have some documents (taxes, copies of drivers licenses, marriage certificate etc.) that contain too much Personally Identifiable Information (PII) to upload to Google or Dropbox. How can I keep these documents backed up and secured using minimal hardware that I may already have laying around.
I'll show how I'm achieving 3-2-1 Backups using an ODROID H3+ w zfs_autobackup & Restic.
The bulk of this presentation will be me explaining the ZFS setup that I described in this forum post:
https://discourse.practicalzfs.com/t/snapshots-to-a-different-zpool-on-the-same-host-as-part-of-a-3-2-1-backup-strategy/1074
Basically, I have an ODROID H3+ that has multiple drives attached. I configure them to have multiple zpools. I then take snapshots of one zpool and send it to another zpool on the same host. This gives me two copies of the data on two different storage devices. Then I use restic to send a third copy offsite. I also use some nifty ZFS features to enable bitrot protection on a single device zpool.
