Take
a snapshot then do an rsync and an excellent way of maintaining
incremental backups for those.

Your idea to use zfs diff to limit the need to stat the entire

limited by this very factor. It takes longer to walk the filesystem tree
than it does to transfer the new data.

Hi Tiernan!
But, now i am confused as to what OS to use... OpenIndiana? Nexenta?
FreeNAS/FreeBSD?
I need something that will allow me to share files over SMB (3 if

like something i can manage easily and something that works
I just started the same migration..
I tried to test OpenIndiana w/Napp-IT, Illumos w/Napp-IT, Debian k/FreeBSD
and Nexenta Community Edition. I tested iSCSI, SMB and NFS. I did not find
time to test FreeNAS. All tests performed as a VM guest on ESXi 5.0.
SMB is based on kernel on OpenIndiana,
