What kind of backup? Is it a dump(8) file?

Did the kernel have a lot of customization? A GENERIC kernel should
boot on almost anything --- which is why "bare metal recovery" seems
a misnomer to me. If the hard disk survives, I simply stick it in
another box and rarely have any difficulties. If it doesn't, I do
a minimal install with the desired final slice/partition scheme on
the new HDD, and simply restore(8) over the top.

Well, I don't know your exact situation, but OOTOMH, the partitioning
scheme you mention seems like wasting a disk unless you want the
final system to have only /, swap, and /backup. Which could be
OK, I guess, but isn't the traditional BSD Right Way(tm).
Also, I'd consider installing a newer release than 6.0, and only
restoring the important stuff. Again, it depends on your situation.
