Chris, where is the TSM DB and LOG? I've seen very slow performance when
the TSM DB and LOG files were placed on some internal disk raid-5
arrays.

With a SAN agent we have achieved 24.2 MB/sec on TDP for Exchange for an
information store of about 15.2GB.

My guess is your anti-virus software or network connection are a
problem.

Hi all

I've been reading various posts about TDP for Exchange being slow
but I can't believe its supposed to be as slow as I'm seeing.   At the
moment I'm only getting approx 500Kb/sec at a time when no other backups
are
running, i.e network and server and doing very little. I've tried
various
settings for TDP buffers/buffersize to no avail.

Environment details below.

If anyone has any thoughts on how I can make this perform better I'd
appreciate it.

Thanks

Chris
