What do you use for automated backups when the host's tool fails?

Contabo's "guaranteed" backup tool

Same. They offered me 2 months credit. I said keep it, I'm moving. Now on Hetzner AX42 for main, Storage Box for backup. German efficiency or whatever.

Restore test last week: 200GB in 35 minutes. Not amazing but it WORKED. Contabo never once restored clean for me.

RAID is not backup

I mirror my mirrors too, but mirrors catch fire together. I learned in Casablanca when building power went out and took both UPS with it. Corruption on both sides of the mirror.

Now: ZFS mirror local, borg to Hetzner Helsinki, borg to friend's box in Marseille. Three copies, two countries, one sleep at night.

Also: zfs set compression=lz4. Your 340GB is probably 180GB on wire. Carl, check your compressratio.

1.14x. Mostly media and VM images, already compressed. Worth it for the metadata though.

Thanks all. Summary of what I'm actually changing:

  • Keep wireguard, MTU 1380 per garykwh's note
  • Add `rclone check` after sync, alert on mismatch
  • Quarterly restore test stays, but add monthly `zfs send -R | zfs recv` validation to cold box
  • Evaluate borg to rsync.net as second tier, not replacing primary

Still reading on the S3 vs ssh debate. Leaning toward keeping it simple.

visit twice: install and decom

This. Simple is better. I ran MinIO for a year, updates broke my setup twice. Back to rsync over ssh, one cron line, one log file.

Following this thread. Currently on Contabo backup too, not failed yet but now I'm nervous.

Check their borg-specific docs. They have a special append-only mode, repository is locked even if your main box is compromised. Cheap insurance.
