I've been using this and it is the best I have found so far.

The only issue I encountered was with trying to back up 2.5TB of new data over a shitty German internet connection, which first took forever (restarting 20 times because they force your IP address to change once a day), and then when trying to prune the backup, ran out of RAM memory and actually corrupted it.

I'll continue to use it, just not repeating those specific steps, but it was not immediately apparent that the backup was completely unusable. Always test your backups (regardless of whether it's about restic, borg, examplecorp expert enterprise backup, or something else)!
