Can timeshift work with ext4 filesystems?

I know it won't have the atomicity of a CoW fs, but I'd be fine with that, as the important files on my systems aren't often modified, especially during a backup - I'd configure it to disable the systemd timers while the backup process is running.

Yep, been using it for a while, incl ext4, you can have scheduled snapshots too, saved my arse few times, especially when you install something that cannot be easily uninstalled like hyperland or similar.

Just getting started with it--but I think so, using rsync.

Can’t you also snapshot LVM volumes directly? So if you have an LVM volume, it shouldn’t matter what the filesystem is, provided it is sync’d… in theory.

(I’ve only done this on VMs that could be paused before the snapshot, so YMMV.)

Yeah, you can take live snapshots with LVM. You can use wyng-backup to incrementally take and back them up somewhere outside LVM. This has been working pretty well for me to backup libvirt domains backed by LVs
