Do ignore me then, I assumed you might know the reference and only I mean’t it in good humour. :) (Without spoiling anything - in the unlikely event you might some day watch it - Mr Milchick is a character that uses ‘big words’. Your choice of words struck a chord.) I will say though, you’re seriously missing out. The cinematography alone is brilliant and the acting exceptional.

As you were, Mr Milchick.

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. :)
