I’ve been using Bash scripts with cronjobs to schedule daily backups, and then sync the backup to BackblazeB2 after the local backup has completed.
However, it’s a bit messy and has a failure point where a locally corrupted repo could be uploaded to the remote repo. It also doesn’t send emails on failure or success.
I’m using crestic to make backups easier to configure.
It makes configuring different backup targets very easy with a simple ini-style config file.
