You mean like "zfs send -i"? If yes, why not just use zfs? There's
zfsonlinux project, with easy-to-install ppa for ubuntu. Or you co=

Thank you for your suggestion. As I know, there is not everything p=

You are mistaken :) The current version is pretty stable, as long as =

don't use compression or dedup. Some problems have been reported with
weird setups (USB disks for example), but I haven't seen any reports =

unrecoverable filesystems.

Thank you for the info. What I wanted from the fs was 108% acuracy, cry=
pt fs, at least some kind one way mirror, two way would be best and com=
pression of the fs would be nice.

Now it seems, that neither of the fsses cancrypt under linux, ZFS is ac=
curate&can reconstruct, BTRFS is accurate&can reconstruct only in mirro=
r, BTRFS can make live incremental backups/snapshots, ZFS can make also=
 send ... and one or two way mirror are future plans for linux ;O)

For btrfs bugs are still fixed on a daily basis, and some reports of
people with corrupted and unrecoverable filesystems.

Neither supports encryption.

I might consider ZFS for a production environment (although it's
officially not production ready), but I don't think btrfs is ready fo=

r

that yet. If you want to be safe, use ext4 with drbd or rsync.

Hmm, I have concluded this afternoon, than ZFS under linux does not hav=
e what I would like to have, but there seems no better solution under l=
inux for now ... thanks for your experience! It helps me a lot. Jaromir
