Also, however you handle your backups, set up a calendar reminder for every month or two to check that they're running as expected. (Backup drive isn't full, cloud service account hasn't expired, correct directories still being backed up, files restore as expected, etc. etc.) I do this monthly, and more months than not I find something to fix on one of the computers in the house. I run multiple types of backups from full disk images to incremental cloud backups, so a loss of any one wouldn't be catastrophic, but it's still a good thing to stay on top of. Just had a hard drive die last week actually, although ironically it was a backup drive...
