Multiple backups may be kept.
Nice work, but if I may suggest - it lacks hardlink support, so’s quite wasteful in terms of disk space - the number of ‘tags’ (snapshots) will be extremely limited.
At least two robust solutions that use rsync+hardlinks already exist: rsnapshot.org and dirvish.org (both written in perl). There’s definitely room for backup tools that produce plain copies, instead of packed chunk data like restic and Duplicacy, and a python or even bash-based tool might be nice, so keep at it.
However, I liken backup software to encryption - extreme care must be taken when rolling and using your own. Whatever tool you use, test test test the backups. :)
Crazy. Though I suspect the copy protection is done by the third party Termly, which hosts the policy.
