I agree too - saving 1-2GB of system data is not worth the trouble of reinstalling it :) On Savannah I switched to multiple backups (one per vserver/chroot/xen/whatever) instead of a full global one. This allowed me to implement backups on LVM snapshots, guarantying consistency. It may be a good idea to do that too. -- Sylvain _______________________________________________ Project mailing list [email protected] https://mail.gna.org/listinfo/project
