This maybe not useful to you - if you are not using Btrfs If you use btrfs - I found it great/fast to make and transfer (send/receive) btrfs snapshots. It is way more "incremental" and faster than rsync, can have a lot of snapshots without costing disk space/performance and the snapshots all just look and behave like separate disk/volume copies.
In fact, I create hourly snapshots on the running system - then keep and backup/send the last one. I keep one week worth of daily snaphots, one moth of weeklies and 3 monthlies. I really only care about data backups and stagger them on multiple targets. I consider local OS disks - best effort only. Instead I maintain tested automated builds - rebuilding a system is probably faster than restoring it anyway. I personally do not use any backup SW as it really is one command line to create and send snapshot. If I would be interested in backup SW - I'd probably use Btrbk https://github.com/digint/btrbk available in many linux distros. For anything else, I use rsync.
