I'm not sure I understand your objections here. Given arbitrarily large disk space, you can set your job and file retention to fifty years if you so choose. Bacula will keep your initial full backup as long as you tell it to. But you can't get by on just an initial full backup and ten years worth of daily incrementals. Doing a restore would require searching thousands of jobs to build the file tree. Name me one backup solution which does NOT have to re-transfer a file if you delete the original backup. VirtualFull jobs allow you to keep replacing that original Full backup without having to re-transfer all of the files from the client again. Of *xcourse*you have to re-copy them from the old job; but then the old job can be purged. Yes, you need the space for both to create the VirtualFull; but you don't have to keep both around after it's completed. If you want to never have to do any job maintenance, never re-copy a file that hasn't changed, never use any extra disk space, etc, etc, perhaps you should be just using rsync? Of course, de-duplicating and creating hard links would become your problem, and then you have to be careful not to update all copies of a hard-linked file when one original updates... - -- Phil Stracchino Babylon Communications ph...@caerllewys.net p...@co.ordinate.org Landline: 603.293.8485 -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEAREIAAYFAlOUh3QACgkQ0DfOju+hMkkHIwCfTqMEJv3et3G+tCE8TWR/cTaG tlYAoNcAcrjrpEkHvZSDz7gVD1BT8O2k =+bnm -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.
