Thanks! I haven't seen this before, though I have heard these 7 general principles. My personal strategy is broadly:
1. daily encrypted restic backups to my local NAS, running ZFS raidz2
2. weekly rsyncs of the backup directory to an offsite machine
3. yearly full offsites of the entire NAS
I test my backups frequently if only because I have some odd persistent bug that eats my zsh history file about once a month. I now have a "recover-latest-history" script that pulls that file back down from the latest restic backup. I have just completed an offsite and exchanged it for last year's, so I can test that now too!
