Re: Zfs Guide

As someone who screwed up their root/sole drive not long ago, this ZFS
discussion is interesting. The rebuilding process might have been easier or
even unnecessary, had I been able to roll back to a snapshot. So even after
reading all of this, I have to ask if this is the right call for me. I use
Freebsd in a VM, have two disk images already with a job to mirror them as
a backup  (not gmirror, I didn't know about that when i set this all up).
Will zfs allow me to run the services I run now with the same ease (booting
into the VM automagically) with the added security of snapshots and
redundancy? I guess a peruse of the fine manual is in order…?
