Anyone know how BRIEFCASE works?

[JethroUK©]

i do most my work on portable pendrive, but i would like to keep a
synchronised backup on my main p.c.

i've read reams about using briefcase but it's still not clear

which is the original, which is the copy?
which version should be in the briefcase, or maybe both should?
do i put a briefcase on the remote source or on the local source (or both)?
do i put the originals in a briefcase from the local source, then drag the
briefcase to the remote? or drag the originals from the local source to a
briefcase on the remote source?

it's a clear as mud

can anyone make it simple, bearing in mind my particular situtation
