That's what tarsnap does, actually. It deduplicates the new archive you're creating against the data in the partial archive, in order to save bandwidth (and indirectly make it less likely that your network connection will flake out again before it finishes). But the way tarsnap stores archives means that you can't have two archives with the same name. Many people solve this problem by adding timestamps to the end of archive names. -- Colin Percival Security Officer Emeritus, FreeBSD | The power to serve Founder, Tarsnap | www.tarsnap.com | Online backups for the truly paranoid
