Dear bacula users,

I am running bacula 2.4.2 on a linux box. My backups are written to 
disk1, a raid that is able to read/write about 80MB/s.

I just did a 'restore all' to another local connected disk (disk2) 
(80MB/s read/write). While the restore was running I watched the 
throughput using iostat. I saw disk1 was reading about 70-80 MB/s but 
disk2 was just writing with 5-6MB/s.
It seems as if bacula does not just read the essential data from the 
backup device, instead it reads nearly all backup data and then writes 
the data that should be restored?

My disk device is configured

#
# File Storage
#
Device {
   Name = FileStorage
   Device Type = File
   Media Type = File
   Archive Device = /storage
   LabelMedia = yes;
   Random Access = Yes;
   AutomaticMount = yes;
   RemovableMedia = no;
   AlwaysOpen = no;
   Block Positioning = yes;
   Maximum Volume Size = 10737418240     # 10GB
}

I think a restore rate of 5-6MB/s is rather slow and I'm shure bacula 
could do better. Any configuration mistake?

Christoph
