I would imagine that his throughput is bottlenecked by the number of
streams.
=20
8 streams seems like a lot to me, unless there's one helluva disk
subsystem. (or he has 4 - 8 disk subsets and is only pulling a stream or
two from each)=20
=20
I found performance hit the toilet when I went above 2 streams per RAID
group. (10 spindles in RAID 5 config, per disk group)

        Shawn,
        =20
        You mean 0.8 to 5.0 megabytes per second per client, right?
        =20
        Have you already performed a test backing up only one client
with the backup server and drives
        as idle as possible? In other words, do you know if this 5 MB/s
throughput is limited by some
        other resource bottleneck or this is the highest that netbackup
client can send to the network?
        =20
        Thank you

                All of our clients use gigabit interfaces.  Our
throughput ranges from 800 kps to 5 Mps depending on file size on the
clients and number of streams running at the time.  We run a max of 8
streams per client and 4 streams per drive using two drives.  We have
tried tweaking the throughput using the streams but haven't spent much
time investigating any other method.  If anyone has a system to tweak
the throughput we would like to try it.=20

                All systems are Win2K=20
                Backing up files ranging from excel/word docs to Unix
file system backups and SQL database backup to 40 GIG.=20

        =09
                Hello
        =09
                Is there someone on this list using gigabit interfaces
on the client machines?
                If so, what has been the backup throughput? Is there a
special netbackup tuning
                to improve performance?
        =09
                Thanks
