@ironicbadger I use a shell script I wrote to snapshot vms and backup them up using borg called pango-backup and borgmatic for file backup all going to borg base. Along with quarterly restore tests I use shift-mon to alert me when a backup service as failed and borg base has a feature that will email you if no data is seen for a certain amount of time. Shift-mon also monitors zfs and smart stats. I'm the shift-mon maintainer so sorry about the shameless plug
