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 reasons: 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- -- J.D. Bronson
