New backup server just dropped!
This server is awfully slow, and the mdraid setup is awfully slow, and I doubt that this will be a good experience, but we now have a backup server again?
- Tried Disko and nixos-anywhere
- Tried using mdraid
- Found that md is ancient and bad
- Found that disko is 100% extra steps, and a lot more complicated and noisy than just formatting your disks yourself
- Found that systemd-boot doesn't support mdraid
- Found that we probably don't need to mirror the boot partition :)
- Found that old hardware is slow
- Found that old hardware can have poor support for iPXE with UEFI, and might do weird BIOS stuff on you when you least expect it
- Reaffirmed that zfs is love
Current disk layout:
- mdraid for boot/root disk
- 4TB WD Red with 500MiB ESP with systemd-boot, Remaining mdraid - Old?
- 4TB WD Red with 500MiB Unused partition, Remaining mdraid - Old?
- zfs pool "tank" for the actual backup data
- 8TB Toshiba MG08 - New
- 8TB Exos 7E10 - New
TODO:
- Document the death of Toriel on the wiki
- Document Bakke on the wiki
- ... describing the poco loco disk layout
- Start backing stuff up
- Restic? Borg? Rsync?
- Make backup retention policy and zfs snapshot system
- Document backup procedures
