It's almost feature-complete: there's one version bump expected in the stream format, to handle files with holes in. There are probably still awkward bugs in there (awkward in the sense that your backups will fail noisily if you hit one), but for my current usage -- disk to disk on the same system -- it seems to work OK. I'm trying at the moment to hack together a working send/receive backup between two systems. As far as I know, the send/receive will work OK, but I'm having problems with firewalls and ssh tunnels right now. :) Hugo. -- === Hugo Mills: hugo@... carfax.org.uk | darksatanic.net | lug.org.uk === PGP key: 65E74AC0 from wwwkeys.eu.pgp.net or http://www.carfax.org.uk --- A cross?
