My setup is easy and reliable:

Bash script that runs restic to backup to backblaze with a 90 day retention snapshot policy and a systemd service + timer.

It runs everyday, everything is backedup to b2, and I don’t need to bother with it.

Pros:

• easy
• quick
• reliable
• private (restic encrypts before sending)
• don’t need to worry about multiple backups as backblaze does it for me (3-2-1 system)

Cons:

• costs (very little) money (backblaze is basically the cheapest provider)
• long restore time as it would be slow to download
• restore costs (pay per gb downloaded)
