Restic is a great piece of software. I use it for more than two years now to do encrypted backups of my home server into Backblaze B2. Took minutes to set up with a couple of lines of script, works like a charm since then. Highly recommended!
Same here! Really happy with the setup. Got an Odroid HC2 doing daily backups to Backblaze B2. The thing doesn't even sweat scanning around 1TB of data. I find the automated pruning of old snapshots also pretty sleek: restic forget --keep-daily 7 --keep-weekly 5 --keep-monthly 12 --keep-yearly 75
Just a heads up in case you aren't already aware, 'restic forget' does not automatically prune data. You also need to pass --prune or run 'restic prune' later. Other wise, your snapshots are dropped from the index but the data used by them still exists in the repo.
