First thing you should check that you DO NOT have client side compression
selected.
It slows down the backup because the processor is too busy compressing and
Legato will only display the actual (compressed) data rate it receives from
the client. Because the drive can't compress it will always show a maximum
of 5MB/sec.

The better method to check the performance is to use the time to backup a
certain amount of date. Backup programs are known to lie about the tape
drive performance, although not always intentionally.

Subject: [Networker] bad performance when backing W2K server's up, but
not with netvaul !


Hey,

We have made som test on backing up a W2K server (with oracle) to a
Networker running on Solaris. The client backup rate average is from
360KBytes/s to 887KBytes/s. The throughput seems to improve significantly
when we are backing few large files up, the throughput raises to 5MBytes/s.
The client is connected directly to the backup server via a switch.

As a test, we tried backing up the same server with Netvaullt backup, the
server was backed up 6,9G in 15 minutes with an average throughput of
7,5MBytes/s !

Does anyone here have som experience in backing W2K server's with Networker,
- what thorughput should we be expecting when backing a W2K server up ?

Thanks.
