I think Sergio has a nice script. I had been doing something similar but 
I know I recall when untarring  (restoring if you will) it was 
complaining about not being able to do things. It was not sockets and 
similar stuff that gets rebuilt on reboot. I do not have failures handy 
to post (yet).

Truth be told? - I am running FreeBSD hosts within ESXi. I can backup 
the hosts within ESXi but need to take the host offline and its a 
cumbersome ordeal. If I had RAID on ESXi, I wouldn't be so worried per 
se but this is not an option. ESXi is very fussy about what is supported 
and I dont have the $ for SCSI and SCSI Raid.

Basically what I need to do is create a fully restorable backup for 2 

1. Easy to create another host on ESXi. I can setup/flavor my fbsd 
install and then once thats done, setup another host.

2. Obvious backup reasons.

...right now, if the SATA drive fails that is hosting the fbsd install I 
am dead in the water. I have 5 hosts on this machine spread across 4 
SATA drives but nothing is mirrored or RAIDed in anyway.

I am at the mercy of these drives w/o any backup-
