I have it add a backup suffix based on the date. It moves changed and deleted files to another directory adding the date to the filename.
It can also do hard-link copied so that you can have multiple full directory trees to avoid all that duplication.
No file deltas or compression, but it does mean that you can access the backups directly.

Not true. Look at the --link-dest flag. Encryption, sure, rsync can’t do that, but incremental backups are fine and compression I handle at the filesystem level anyway.

Isn’t that creating hardlinks between source and dest? Hard links only work on the same drive. And I’m not sure how that gives you “time travel”.

Snapper and BTRFS. Its only adjusts changes in data, so time travel is just pointing to what blocks changed and when, and not building a duplicate of the entire file or filesystem. A snapshot is instant, and new block changes belong to the current default.
