If I use XP's built in backup utility to create a .bkf on my network storage, could I then come back and restore from that .bkf to an entirely different machine?

So here's how it would go:

Lappy 1 creates a .bkf on NAS

Lappy 2 (new machine without much on it) restores from the same .bkf

NOTE: I don't currently have Lappy 2, but I do need to back up Lappy 1. Lappy 2 is coming in 6-8 weeks or so and will run XP. So there will be an initial backup, then a number of incrementals between the initial backup and the transfer to the new machine.

Does it work this way? If so, any gotchas? If not, what's the preferred way to handle such a transfer?
