The report states that that 7 files were expected and 7 restored, so I guess this includes a couple of parent directories.

If that's a backup of a single host, that sounds ... bizarre. The only explanation I can think of is that there's a directory tree sitting in somewhere between those seven files in the directory, that contains a vast quantity of data.

It is more a function of FS order and concurrent jobs. John -- SOLARIS 10 is the OS for Data Centers - provides features such as DTrace, Predictive Self Healing and Award Winning ZFS.

[Bacula-users] Write ordering?
I am just testing bacula prior to deployment and restored 7 files from one directory from a backup of 3TB. This backup is stored on 3 LTO4 volumes and in order to restore these 7 files, it read from the first and third LTO4 volumes, when I would have expected them to all be adjacent to one another. Is this a deliberate policy to spread data across tapes or a reflection of the FS layout of the data being backed up?
