Are there any provisions for hard link savings for backing up many similar machines?
I ask because I have 2000 (yes, two thousand) machines to back up. At least 90% of data is the same... basic Linux filesystems, mostly / and /var and /usr partitions. I wonder if it would be worthwhile to add a feature to rdiff-backup that would look to hardlink files that different rdiff-backup archives have in common? Right now, the hard link savings is only per machine's, say, /usr partition. Sure, the incremental backup from the same machine benefits from this; only any differences are recorded. But right next to that archive directory on the backup server I have a thousand other machines with a /usr archive that is mostly if not entirely identical. Why not have the option to make rdiff-backup be able to use some sort of higher level "all these archives can share hardlinks" capability? The space saving would be staggering for multihost backups. -- Joshua Jensen joshua aatttt joshuajensen ddooottt org "Some people are like Slinkies, not really good for anything... but they bring a smile to your face when pushed down the stairs." _______________________________________________ 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
