Backup speed

[Arthur_Lupker]

Hi,

I backup several windows servers with aprox. �5 MB/s is this ok?

[Stumpr2]

It is OK as long as you make the intended backup window.

[Arthur_Lupker]

Is it thru that intel/windows servers can provide max 5 MB/s?

[Stumpr2]

They are capable of much faster throughput, but tuning would be required. If you definitely need more speed then I suggest you read:

VERITAS NetBackup (tm) Enterprise Server / Server 6.0 Backup Planning and Performance Tuning Guide for UNIX, Windows, and Linux

http://seer.support.veritas.com/docs/281842.htm

Although this is titled for 6.0, there is a wealth of information that applies to ALL versions of Netbackup and even other products....


This is a MUST read document for Netbackup!

That sounds about right. Especially if you have a mix of many small and medium sized files. Also, this is dependant on many many variables (NIC speeds, tape drive speeds etc)

Here is a nice article where you can take NIC and Tape out of the picture to see if the filesystem is the bottleneck.

Hi Arthur,
The backup speed looks pretty good. But you can further improove the speed factor by a measure of +_ 1 to 2 Mbps based on the following criterias

1) implement a separate LAN card for the backup purpose on the client machine.

2) put the LAN card to 100 Mbps and then implement the same on the switch port.

3) implement qfe card on your master server. in place of a single LAN card for all the backups, go for multiple LAN cards and segregrate and classify the backups according to thier class and types on each particular lan card.

for example :
if i have four UNIX clients and four Windows clients and four SQL clients

I ll use 4 qfe cards on the master server

1 qfe : for the unix backups
1 qfe : for the windows backups
1 qfe : for the SQL clients backups

I hope this helps you out in some way or the other with the backup throughput.

One more point, use the FULL DUPLEX on the LAN card with 100 Mbps .

Wow,
sorry for all the duplicate postings... It was giving me a cryptic error when I posted so I tried a number of times. Apparently it was working. These forums are really acting goofy!

[Arthur_Lupker]

Thank you all your your info, now I know for sure that I'm on the right way

No problem Aaron.
I had the same thing happen to me with duplicate postings in a thread I started.
