Hello,

   I'm using external USB drives setup with the vchanger system to 
simulate a tape library, and I've got a problem where the backups are 
running horrendously slow.  IE, the full backup of my small server 
(5.5GB) takes 8 hours and 10 minutes, and the backup of my 690GB file 
server takes 5-6 DAYS.  The problem doesn't seem to be the USB drives 
themselves as I can push 3GB/minute to them easily which means the 690GB 
backup should take under 6 hours.

   Does anyone know what could be going on here?  Right now the Bacula 
director and storage-director are running on the file server as I 
thought that would be faster, but maybe that's a bad idea? There doesn't 
seem to be a big load issue, at least not enough of one to make the 
backups take 20-25x longer than with rsync...
