Disaster recovery.

Thanks Dan, I think that is exactly what I am looking for.

Possibly the last few questions.

1. After fdisk/disklabel/newfs, how do you drop to the shell (can I drop to 

2. Once in that shell, are all shell commands avialable? (or at least mount, 
cp, restore, etc).

3. If the old disk is 36 GIG and the new disk is 74 GIG, AND I partition 
every filesystem bigger than the old ones on the old disk, then do the 
restore of the 4 filesystems, will it work or do the new filesystems really 
need to be exactly the same size?

4. All my servers are capable of pxe boot. Would it be worth while adding a 
disk to a server with nothing else than a fresh virgin install of freebsd (I 
have 0 exp with pxe, so if I am off here forgive me).

Thanks for the help thus far.
