to back up the MBR, so I can recontruct the boot program and partition
table. But they don't mention that in the Handbook.
While that will back up the Master Boot Record, it's not sufficient for
the general case of MS-DOS
Thanks again guys. My final series of steps to take full backups:
bsdlabel ad4s1| ssh -p 2 nlan...@localhost dd
of=/home/nlandys/backup/bsdlabel_ad4s1
dmesg -a | ssh -p 2 nlan...@localhost dd
of=/home/nlandys/backup/dmesg
dd if=/dev/ad4 bs=512

Lastly, it says save all boot messages. Do they mean the output of
dmesg? Why is this useful?
It would show what hardware was in the old machine and what services are
running on startup. Backup in general is making copies of information
you won't need as long as you

You can do all this though it might be more than needed. Only
the level 0 dumps are needed.

Just a general note: backup to a hard drive isn't bad, but it's not the
same as removable media. One failure can kill all of your backups...
That's why it's often a good choice two have at least two
hard disks

Thanks for your help guys. I have decided to attempt the following.
With a filesystem snapshot, take a dump 0 of all filesystems. Back up
these dumps to a 500GB disk I have sitting at home (the server I'm
backing up is in a data center). Perform this maybe once a week or
once a month.
I am now

Take a UFS2 snapshot and then backup the snapshot. A similar approach
using ZFS snapshots would also work.
See the handbook for more details.
