I'd like to hear what happens with your shadow copy testing. I've been<br>
looking into it for my win2003 replacement on which we use Shadow Copy.<br>
<br>
How does btrfs relate to samba's vfs option? I had not even thought of<br>
using btrfs on my servers. Thought it was still under development. Is it<br>
ready to deploy? If it offers an easier way to do something resembling<br>
shadow copy, I'm in. Since I'm just getting started, now would be the time<br>
for me to jump on board.<br>
