I got my first backup jobs running on Bacula, and while they appear to be working, they are extremely slow.  The client is reporting only a 200-600 KB/s rate.

The configuration is mostly a default install and backups are being done directly to file, never to tape.  This particular job backs up 3 Novell eDirectory servers mounted by nwmap and symbolic linked to /mnt/<ServerName>.   Backups get written to /mnt/Herbert which is an NFS mount to our QNAP NAS.  Manual file copies work fine over these network connections with Frodo being a 100 mbps connection, and everything else being 1000 mbps.

 

I have already attempted removing MD5 and GZIP from the FileSet, as well as toying with the Maximum Network Buffer Size options on the Storage Daemon's Device Resource as well as in the FileDaemon's FileDaemon resource.  MD5/GZIP had little or no effect on the speed, and attempting to raise the buffer size made it go even slower.  I've also tried turning on attribute spooling, which also had no effect on the speed.  I'm not sure what else to check. 

 

While the backup is running, network traffic is miniscule (floats between 0 and 30 KB/s) and CPU usage is barely even being touched.

 

Here's a top printout:
