Hi
I am just about to go on leave, but sounds like the Network needs to be looked into, and check the links between the Master and this Server, including any switches and all speeds.
 
Unless anyone else can come up with a suggestion :-(

Simon,
I already updated NIC drivers. There is no firewall between NBU Master and Exchange.
 
I'm running 6.0 MP4 on both master and client. No exchange cluster in the environment. I have enable level 5 logging and I see the 10054 error with connection reset by peer.
 
I was even thinking about upgrading the maintenance pack to the latest but unsure if it would help.
 
I noticed something today when monitoring the network traffic on master and client. Backup starts for info store and once tape is mounted traffic begins to flow and both machines have heavy traffic. At a certain point, usually 3-5 minutes into the backup, traffic dies to zero and after approx 1 minute, the job fails.
 
Any ideas?
 
Anas

Usually file write error tar is normally indeed NIC / Network related. Can also occur if the boxes are going through a firewall and rules are not configured correctly.
Is it worth updating the NIC drivers just to be sure? I appreciate nothing has changed, but even if there has been a minor change on the speed of the Network, it may all need to be investigated.
 
What Maintenance Pack are you on? In fact, what level of NBU is on the client and the Master? Also, confirm this is a single exchange server, and not in a cluster.
It may also be worth enabling full logging on the client itself to see what Netbackup is really complaining about. I do mean the NetBackup logs and verbose logging to max (normally 5).
 
Logs are found in C:\Program Files\Veritas\NetBackup\Logs\bpbkar (assuming its been created, if not run the batch file in the logs folder).
Stop / Restart the NetBackup client service and try the backup again.
 
Hope this is of some help
Simon

That’s what I meant … nothing significant in the event logs during the backup. I have my maintenance schedule for mailbox and public folder store to run between 2 and 6 am during which the backup is running but I have never had problems with that before.

 

The backup is Info Store and BLB (which I really hate too)

But what about the event logs "during" the backup itself? Specifically, the Application log during the backup?

Also, is the problem related to just doing an "Information Store" Backup or a BLB (Brick Level Backups that I really, really hate!)

 

Thanks, Simon

Simon,

Actually I have rebooted several times and nothing significant showed up in the event log.

Hi

Have you rebooted the client Server? If so, can you do this?

Any error messages or warning in the System or importantly, the Application logs at the time of the backup?

 

Simon

Subject: [Veritas-bu] Exchange Store Backup

Ive been running into backup issues with exchange 2003. I have had a 2 policies for over 2 years now. One for Information store and one for mailbox store. Each works separately at different time intervals. Starting this week, I would get error “FTL - tar file write error (10054)”. When I looked it up, it stated that there was most likely an network error. Nothing was changed on my network level and all NIC’s are full operational.

 

I have no anti-virus installed, I removed and reinstalled agent, I even teamed the NIC’s on exchange. Still I get the same error. The error comes usually after a couple of minutes into the backup starts.

 

If anyone can give me some opinions please.

 

Thanks in advance,

 

Anas
