I just got my home server up and running and was wondering what you guys recommend for backups. I figure it will probably be worth having backups on cloud servers tjay are external, are there any good services yall use for that?

I use Restic + Resticprofile to back up everything and store it on my local HDD.

Then, I use Rclone to sync the local repository to Backblaze B2.

Here's my general setup:

Resticprofile doesn't let me run other shell commands on a schedule, and because I wanted everything in a single configuration, I just created two new profiles which call the backup command. I then made the shell commands run before Restic, and then finally killed the instance before it got to actually run, which effectively does what I needed.

It's the first time I hear about resticprofile and it looks nice. So far I've been using crestic for configuration files. Do you know how they compare?

[–] spez_ 1 points 1 year ago

It seems like they have the same objectives - allow for easier configuration of Restic. I've never heard of Crestic until now. I'd say stick with what you're comfortable with
