Have you tried storebackup? http://storebackup.org/ It at least purports to do what you're asking. I'm investigating it to replace rdiff-backup because several times now, my rdiff backup destinations have become "corrupted" and no new backup sessions would complete until I made a new destination. This problem has not happened with storebackup. _______________________________________________ rdiff-backup-users mailing list at [email protected] http://lists.nongnu.org/mailman/listinfo/rdiff-backup-users Wiki URL: http://rdiff-backup.solutionsfirst.com.au/index.php/RdiffBackupWiki
