I use borg extensively as well. One thing I haven't found a good solution for yet is monitoring. How do you all keep track of whether your backups succeeded? I'd like to receive an email if a scheduled backup didn't run. The only thing I have for now is rsync's feature where they warn you if your data hasn't changed by X kb in the last Y hours/days but I find this lacking because multiple machines write to my rsync account. It'll only warn me if none made any change but I'd never know if only a few failed. Same thing if there is nothing new to backup, I get an email from rsync.net but I don't know if every backup job failed or there is just no changes.
