I keep two versions of the ReaR backups on each backup drive. If
machine A fails during the backup run then I have the previous run to
fall back on. In the unlikely event of machine A failing and backup
drive A failing then I need to reinstall from scratch and then restore
important filesystems from backup drive B.

If machine A and backup drive A and backup drive B fail simultaneously
then I pack it in and become a farrier or something. :)

Your backup schedule should be based on how much time you can afford
(or are willing) to spend recovering from complete failure. For me this
usually is once a week for the ReaR backups and every 2-3 days for the
restic backups.
