I may be missing something, but this sounds like a bug. I'll look at it.
By the way, please don't try to run simultaneous jobs in the same FD if you
use the new VSS feature -- it will not work correctly with more than one job
at a time.

Currently on my Windows 2K server two concurrent jobs are running (one
to drive 1 and the other one to drive 2). Both are running at about
1 MB/s (instead of 100 KB/s)!
BTW: I had to use different pools to get the concurrent jobs working. Is
this ok? My first try was to do something like that
Job {
Client = win2k
FileSet = "win2k 1"
Storage = tape1
Pool = WeeklyPool
}
Job {
Client = win2k
FileSet = "win2k 2"
Storage = tape2
Pool = WeeklyPool
}
In both drives a valid tape was inserted and the pools are defined with
"Accept Any Volume = yes", but the second job started was always
complaining:
Cannot find any appendable volumes.
Please use the "label" command to create a new Volume for:
Storage: tape2 (/dev/nst1)
Media type: DDS-3
Pool: WeeklyPool
So I created a pool WeeklyPool2 and moved tape2 to that pool and changed
the job accordingly. After this the jobs are really running
concurrently. Is this behaviour correct?
Cheers,
Carsten

I'll be making a new beta release in a day or two.

The AP is in the same room as the laptop so connection strength is permanently excellent and I can transfer at ~5MB/s from our Samba server in both directions so I don't think that is it. Anything else I can try to identify the problem? Cheers, -- Dominic Marks --- This SF.Net email is sponsored by the 'Do More With Dual!' webinar happening July 14 at 8am PDT/11am EDT.

Unlikely, but I would be happy if someone tried.
Recently a user reported serious performance problems and stalled backups. The
bottom line was a NVidia ethernet card with an old driver. See the Win32
chapter of the development manual for more details.
Bottom line: check that your hardware/firmware are up to date as well as the
network drivers. If you have an NVidia network card be suspicious.

And then I wouldn't expect, that a) the performance of a linux client is 8x better, b) I got a similar performance from the windows machine before. I did even test portable mode, but that doesn't change anything either. And I just have no idea what to look for: CPU usage of both the windows machine and the backup server is low and memory usage reasonable. At least not different to the time, when I got the good performance on the windows machine... The sqlite database is just about 65 MB currently, so I don't think there's a problem. --- This SF.Net email is sponsored by the 'Do More With Dual!' webinar happening July 14 at 8am PDT/11am EDT.
