Using a CD to make initial copy

[Jay Strauss]

Hi,

I have 20Gb of data I need to back up.  It takes too copy it across
the internet.  Is there a way I can copy it locally to some removable
media like a couple of DVDs, then bring them to the target machine,
copy onto the target, then run rsync to grab any updates?

What if the target doesn't have the same users as the source.

Is there a suggested recipe for this?

Thanks
Jay
