No, that won't quite work as you intend - the backup directory contains two things: a current copy of the file system you're backing up, and (in the rdiff-backup-data directory) the necessary information to convert the current copy of the filesystem back into an old copy (i.e. as of previous backup dates) if you want to revert to a previous state. So just backing up the rdiff-backup-directory isn't that helpful without also having the current copy of the files. However, the strength of rdiff-backup is in backup to disks, not DVDs. And since you're backing up to disk, you may not *always* need to also write to DVD. So you could do something like this: * run rdiff-backup, say, every night to have a current copy of your files on a separate disk. * then, write the whole backup to DVD or some other media less frequently (once a week? once a month? depends on your needs). Note that this less-frequent external backup would still contain the information from all the previous backups, since all of those increments are saved separately in the rdiff-backup-data directory, unless you clear them out. I hope this helps to clarify how rdiff-backup works.
