I like that idea. But whereas the initial snapshot takes up almost no disk space, I think that deleting its rdiff-backup-data directory would cause it to swell in size by the size of the rdiff-backup-data directory, or perhaps somewhat more (since snapshotting works at block level). Better just to rsync to it ignoring the rdiff-backup-data directory on the destination (I think using rsync --excl /rdiff-backup-data should do it). Then, as you suggest, run rdiff-backup from the snapshot back to the original location, again ignoring /rdiff-backup-data on the source (rdiff-backup-data --exclude /rdiff-backup-data) - or maybe rdiff-backup would ignore it anyway? Cheers, Dominic
To correct what I wrote above, by experiment I have realised that deleting data from an LVM snapshot does *not* cause substantial swelling of the snapshot. So Chris's suggested strategy should work fine.
