Rsync backups can be setup to deal with this. I have rsync setup with daily incremental backups, the main sync to a 'current' folder and the old version of changed files staying in a weekday named folder (eg. Monday). So I have a rotating 7 day period to recover files. On top of that I have a monthly long term backup of the last old version of that month. This provides an arbitraribly long monthly window to recover from. Rsync is very versatile.

Yeah with enough scripting, you can rebuild a slow equivalent to a real backup program, that will also use 10x the disk space.

Yep. But it works and has worked for over 20 years. Various backup software has come and gone in that time but rsync has been a rock.

Fwiw, Borg is coming up on 10. 12 if you include the project it forked from. I like the simplicity of rsync approaches, but Borg seems to have longevity and widespread use.

Restic is also around 10 years old... at least based on it's github commit history. I should probably look at them again at some point. Hard to get motivated to replace a working system for some disk space.

If you do end up kicking the tires, it might be worth looking at duplicacy as well.
