Backu Exec failing the backup, strange!

Hi all,
 i have our Veritas Backup Exec 10.0 rev 5520 failing since some days.

i have selected the Whole Exchange Storage Group, the single Mailboxes and the single PFs, the file server.

First it was failing to backup the single mailboxes, telling "0xe00084f8 - The network connection has been interrupted" (freely translated from italian version) on the single mailboxes object in the report.

Then i tried to uninstall-reinstall the agent and to recreate the backup job. the job started complaining about the lost network connectivity with the Exchange store and FAILED THE WHOLE EXCHANGE OBJECT with:

V-79-57344-65072 - Exchange Server is not responding. Backup set canceled.
V-79-57344-65072 - Exchange Store service is not responding. Backup set canceled.
V-79-57344-65072 - Lost connectivity with the destination system. Backup set canceled.
(freely translated from italian version)
Yesterday i tried to restart the Backup Exec Agent. Today has completed the exchange backup, but is complaining about the FILESERVER!

V-79-57344-65218 - There was a problem accessing snapshot handle.

Other notes:
Tapes are more than enough to contain all the raw data.
Tape drive is clean
Tried with new tapes and old ones.

What is going on here? I need an expert advice! :-)

I would suggest from the errors you're getting that it might be some form of communications failure between the servers. Did you have backup exec set to run over its own physical network? Hae you changed any network cards or updated drivers? Have you moved it to a network with more traffic?
We find that if you backup the exchange server and the fileserver as separate backup jobs, albeit to the same tape, then we have much less issue with the backups failing. Just dont forget to set your overwrite protection.

Also sometimes I've found that we've literally had to reinstall the Symantec software from scratch. If you get get a copy of 10d then I beleive the license from 10.0 is still valid. It might be worth the upgrade.

Our copy hasn't failed a bkp job for years!

Now we moved DataCenter Physically and it started to fail that strange way....

I would like to understand WHY.
Everything went fine in the move.
Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

i changed from hp 4120gl switch to juniper networks 4200 ex with a core switch with two 4500ex connected with each floor with two fc 10 Gb aggregated. I can't believe there could be problems passing from a network that performs 2 to a network that performs 20... Configured directly from the vendor. Anyway servers are connected on the same switch stack of 4200ex. Network performs super during the work hours, but i'll search in the snmp logs, although i think i'll find nothing.. Thanks for the suggestion
I'd still suggest splitting the exchange backup and the file backup. At the least set the exchange backups to be first in the selection list order.
We look after dozens of servers, mainly sbs that run various editions of backup exec and often the only option seems to be the reinstall. I guess it could be to do with updates from Microsoft butI have never been able to tell for certain.

OK, i'll give it a try.

Nothing to do...
Both the jobs fail...

it fails on files and on single mailbox (different servers)
it backs up the entire exc storage group correctly

Can you post the job log(s) for me.
Particularly the failure parts.

Hi acstechee,
sry for the delay...

My logs are in italian....
I exported those in text and passed to Google Translator and anonimized. Here is the file attached.

I splitted BKP Jobs as you suggested, here is only the mail bkp job (that fails on single mailboxes part)

As already implied by previous posts, this appears to be a network related issue.  You have made a significant network change in your environment and now cannot backup your file server and your Exchange Server, while sometimes allowing one or the other to work.

Are the servers and the backup system on the same switch, or do they pass through the core?

Hi Delphineous and Acsteeche,
 today i verified this problem was related to the NIC team (broadcomm nics) on the backup server.

Disabling that team solved the issue.

Thanks all for your help.
