@daftaupe @martin What’s the advantage over ext4? I really have no idea.

@flowfx @daftaupe for example #snapshots and #compression (at least that's what i'm looking for)

actually, i'd also like to have #deduplication, which is, however, apparently not yet properly #supported

@martin @flowfx Actually it's not live dedup yet, but dedup is working when run as cron jobs for example (haven't tried that yet). I'm mostly using snapshots, subvolume and compression for some partitions.

@martin @flowfx Also you can use cp='cp --reflink=auto' so that it makes use of the copy-on-write abilities

@daftaupe @martin Thank you!

@daftaupe are your devices encrypted? (if so, how?)

@martin On my laptop yes :) I wrote a little article on how I use that with UEFI : https://tech.cccp.io/post/19_linux_uefi_boot_manager_configuration_encrypted_root_swap/

@martin It's basically luks on the whole device, then once decrypted it's a btrfs partition with many subvolumes.

@daftaupe
That's the setup that I had in mind! 💪

Thanks for sharing your experience, I'll give it a try! 🧐

@martin Good luck ! Don't hesitate if you have any question.
After you're done take a look at btrfs send/receive features for your backups. I have a little script I can share later if you want.
