SQL Replication

I have database replication from one server to another over a rather thin link. They are out of sync so I would prefer to re-snapshot. Unfortnately the link is thin and performing a snapshot would incur huge transfer delays. I would not like to perform a snapshop but create a backup that can be hand carried. I've seen how to do this on the web but this seems to be with new publications and not exising. Would it be easier to delete both publication and subscription and start again or is there any instruction anywhere with an existing publications?
