It looks fitting to other services like Rsync. I am running on an
external RAID6, so I assume the discs and caching is just low, as I
have several file storages >80TB on that device. No SSD or so.
Initially I tested the drive with about 400MB/s, so that fits around
the maximum read speed of the discs coming from the raid.
Are there any tweaking parameters I could try?

Please try the bacula-sd parameters. This is from our Quantum
Superloader 3 LTO-7 definitions. See if it makes any difference for
you. Despooling sustained ~ 290MB/sec from an SSD Raid 1.
bacula-sd.conf:
Device {
...
# 300 Mb/sec = eof filemark every two minutes, this is not max size
of YOUR files... #8-)
MaximumFileSize = 36G
MaximumBlockSize = 1048576
...
}
Another point would be spooling of file attributes to reduce
intermittent access to you sql server.

Hi
okay, I will try that. I had set no BlockSize but my Filesize to 3TB
to avoid permanen spooling and despooling.
Let's see if that changes anything.
I reduced the filesize to 36GB but that did not change anything for the
speed. so I will stick with 3TB spool file size. The blocksize did not
change anythign either, the speed is still around 100 MB/s with tops 200.
Cheers
