resuming backup after network has disappeared for a while or after sleep is problematic and mostly impossible to do in an atomic way. If you have enough local storage, I'd put a local backup process (restic/borg/bup), and then rclone/rsync your backup repository to remote storage. If you don't have enough local storage, you can restic or bup to a remote server reliably as long as you can complete one scan. On my laptop with a 256GB SSD, a common restic scan with cold caches takes less than 15 minutes; an hourly backup is a few hundred megs, a daily backup is often close to 2 gigs, depends on how many files you have, and how many (and how much) of them change. Alternatively, you can do an rsync-based snapshot.
