Fine.

It very much depends on what kind of restore you're talking
about. If you need to restore *everthing*, then yes, I'd suggest
to do this from some other distribution, as you might have 
problems overwriting certain files in / or /usr.

But if you just need to restore one file, then no, you don't
need another distribution. How did you make the backup? Into
a cpio/tar or with something like rsnapshot, which will, essentially,
just copy all the files over to some other directory?
