Hey Gene, I don't have any advice to give in the matter of upgrading FreeBSD, but I wa= nted to make sure you knew: ZFS has "send/recieve" commands that you can use= to send complete images of ZFS filesystems between two computers that are r= unning ZFS. This means that you can send a full snapshot of your FreeBSD 8 m= achine to some other machine that can be used as a backup PC; that way, it'l= l even come with all the ZFS settings built into the file system, which make= s an extremely accurate backup. You probably knew all this, but I just want t= o make sure. :) --Matt > On May 28, 2014, at 12:35 PM, "Gene" <fbsd@brightstar.bomgardner.net> wrot= e: >=20 > Thanks - in spite of the fact that I've been running a FBSD system since=20= > around ver 6.0, I am still in many ways a neophyte.
