This is really hard to do when everything is bundled into big volumes, and volumes are expired as units. It'd be necessary to compltely re-design the way storage works to do file-level deduplication, and it's not as easy to do (efficiently, with proper retention etc) as it first seems either. -- Craig Ringer ------------------------------------------------------------------------------ _______________________________________________ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
