Hi all,
I wrote a little java program that combines Rsync and ZFS snapshots to backup
remote servers.
configuration is really easy, check it out at

Comments are most welcomed.
I assume that the motivation for this is to have a disk-to-disk backup
of systems that don't support ZFS. One thing that may be useful is
use of the --inplace option to rsync. This way when files that only
partially change[1] are backed up, only the parts that are different
are written to the zfs file system.

is still being written to

Since you already have a zfs snapshot of the previous state, there
would seem to be no need for --backup. Also, the warning is not
terribly relevant for the same reason.
Great point, I was mistakenly assuming rsync did it in place anyway.
it's already possible to control the rsync options, but I`ll make
inplace the default.
