Hello,
Just started using Bacula and at this time (early stages) I find my
UNIX/Solaris full backups are running at a good speed, but our window
server is slow. There is a chance it is just the number of files (Yes,
I am ignoring profiles). My questions:
1) I have added "Maximum Concurrent Jobs" to my clients FileDaemon,
but is there a way to prove that Windows client is using it?
2) Any web links to how I can monitor a client backup, to examine what
is happening.
Thanks

Hi Andrew,
When you brought it up, I had a look at my setup. I'm backing up both
Linux and Windows servers.
The Linux server backups are running at about 30 Mbyte/s (2x1Gbit NICs)
with line compression, whereas the Windows server backups are running at
about 22 Mbytes/s (2x10Gbit NICs) without compression. The connection is
10 Gbit from all servers to the Bacula backup server. The values
mentioned are for full monthly server backups (a couple of TBs).
What I did notice however, is that small incremental backups are an
order of magnitude slower for the Windows servers, compared to the Linux
servers.
I'm not going to speculate, but compression would probably speed up
things somewhat for the Windows backups, however not significantly.
Also, VSS snapshots under Windows may have a huge impact on the overall
performance for smaller backup sets.
For me, the current performance is sufficient, but there is certainly
lots of room for tweaking. I've been running this setup for about 9
years now, just improving the hardware now and then. Don't fix what's
working...
Best regards,
Peter
