dump/restore over ssh question

[Andy Firman]

I am following this guide: 
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/backup-basics.html
and successfully dumped /, /usr, and /var over ssh to another box and
called them root-back.gz, usr-back.gz, and var-back.gz.

But I can't figure out the restore part.  Let's say I replace the
harddrive and need to restore the 3 dumped filesystems.

How do I go about this for my 4.11 box?

What I have done so far is: 
1. Replace the hard drive
2. Minimal install of 4.11 so the drive is partitioned the same as before
3. Copied the 3 dumped/gzipped files over ssh to the system w/new drive
4. Then I booted into fixit mode, and am stuck here...

How do I restore the 3 filesystems?

Thanks,
Andy
