What’s your backup target (to where are these backups being sent?)?

Are you looking for actual Backup-strategy apps or just data sync as a form of backup (I wouldn’t recommend this approach unless you can setup multiple destinations and some form of differencing).

Also, how will backups be validated? Will there be a monthly check for a while to verify files? Maybe a quarterly restore test until you trust it’s working right? Who’s going to do this?

Just some questions to consider. Good luck, backup is so much fun!
