I know WHAT is happening, just not WHY I am hoping someone sees something obviously bogus in here.

The same line StorageGroupPolicy = "FreeSpace" is in each JobDefs resource in bacula-dir.conf Does anyone see a stupid mistake made on my part ? Does anyone see a way past this mess ? Thanks in advance. _______________________________________________ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
