TL;DR: don't panic, all is good. :-)
Longer version:
- borg 1.x style “append-only” was removed, because it heavily depended on how the 1.x storage worked (it was a transactional log, always only appending PUT/DEL/COMMIT entries to segment files - except when compacting segments [then it also deleted segment files after appending their non-deleted entries to new segments])
- borg 2 storage (based on borgstore) does not work like that anymore (for good reasons), there is no “appending”. thus “—append-only” would be a misnomer.
- master branch (future borg 2 beta) has “borg serve —permissions=…” (and BORG_PERMISSIONS env var) so one can restrict permissions: “all”, “no-delete”, “write-only”, “read-only” offer more functionality than “append only” ever had. “no-delete” disallows data as well as data overwriting.
- restricting permissions in a store on a server requires server/store side enforced permission control. “borg serve” implements that (using the borgstore posixfs backend), but it could be also implemented by configuring a different kind of store accordingly (like some cloud storage). it’s hard to test that with all sorts of cloud storage providers though, so implementing it in the much easier to automatically test posixfs was also a motivation to add the permissions code.

Here's a very actively developed GUI https://github.com/garethgeorge/backrest - imho it has come the farthest and is the easiest in terms of use and ease. I have tried too many other restic GUIs and settled on this.

For anyone looking to migrate off borg because of this, append-only is available in restic, but only with the rest-server backend:
https://github.com/restic/restic

which has to be started with --append-only. I use this systemd unit:

Rsnapshot
a tool for backing up your data using rsync (if you want to get help, use https://lists.sourceforge.net/lists/listinfo/rsnapshot-discuss)
-
I maintain my incremental backup and handle the rotation with a shell script (bontmia) based on rsync with `--link-dest` (it creates hard links for unchanged files from the last backup). I've been using this on top of cryptsetup/luks/ext4 or xfs for > 10 years.
This is the tool I use: https://github.com/hcartiaux/bontmia
It's forked from an old project which is not online anymore, I've fixed a few bugs and cleaned the code over the years.

Cool, but looks like it's going to miss capabilities, so not suitable for a full OS backup (see https://github.com/python/cpython/issues/113293)

rustic currently is in beta state and misses regression tests. It is not recommended to use it for production backups, yet.

If anyone cares about preserving hardlinks and overlay2 directories. The binary is a drop in.
