Hi Wayne

I'd have to disagree with your colleague.

We got 580MB/min (last night's backup) with TSA600 on one of our Netware 6 
servers that gets backed-up by a non-Legato product to a directly-connected 
tape drive.  This is a mix of large and small files.

Cheers,
Ryan.

I hope this helps, but I just got this message from my colleague at
brainshare today:

Subject: tsa speed

apparently tsa600 is toast.

they measured it at a max backup speed of 400MB/minute

the new TSAFS is a replacement (sp4) and they can get 6GB/min.

Greetings...

Server - Solaris, running NetWorker 6.11
Media - DLT7k
Client - NetWare 6.5 running NetWorker 4.21 client.  NSS volumes on
NetWare.

We have a couple of NetWare 5.1 servers using the NetWorker 4.21 client and
I get 'satisfactory' throughput on backups as long as I split large volumes
into muliple streams.
However, I am trying to determine whether there is hope for improvement on
backing up tons of 'small files.

We are deploying NetWare 6.5 and have noticed that the backup speeds are
significantly slower... especially with 'small' files, such as in the SYS:
volume.

Please share your experience with backing up NetWare 6.x servers.
