Need help - Remote Backup keeps failing almost every night now.

[ESabo]

Latest VSS from Microsoft (no errors doing a list writers) - Latest Remote Agent on server along with the media server being the latest also.

I don't know what else to do.    Something the byte count goes high and then fails sometimes it goes very low.

Open a support call but they said it is environmental, never gave me what to do to correct the environmental problem.  

I am getting the following:

Backup- \\XXXXXXXXX\C: V-79-57344-65072 - The connection to target system has been lost. Backup set canceled.
V-79-57344-65072 - The connection to target system has been lost. Backup set canceled.

Try to defrag the remote server and still didn't help.   Anyone?    

I don't know what else to do.

[ESabo]

Still happening.     

I just don't know what to do.  

Tried opening a Symantec Support call but with all logging turned up, they can only say it is an environment issue that is causing the backup to fail.

Happened again tonight.

Does anyone have any suggestions or something to try?

Well, finally after days of endless backup jobs failing, I opened a support call this morning.   After about 2 hours and getting my call to second level support still nothing.   Symantec is blaming Microsoft Volume Shadow Copy Service.    But I disagree because with the remote agent turned off, I am able to perform an NTBackup on the system (which I believe is a good test because NTBackup uses VSS).

If I do a vssadmin list writers prior to BackupExec 11 D running - all writers show it a stable state.

Then I run the vssadmin list writers AFTER I try a BackupExec 11 D job, some of the writers are showing in a failed state.

At this point, I had to open up another call with Microsoft to prove that VSS is not the issue.  

This is getting to the point, that I think I am done with Symantec BackupExec 11 D because it just does not work in my environment.    I am hoping that Microsoft and Symantec will find the cause.

I will keep everyone posted in my journey.

Maybe Version 12 will resolve this issue?

Still failing - I have a support ticket open with Symantec Support but all they have done is blame Microsoft.   So I open a call with Microsoft and they said it is symantec causing the issue.

What is a customer suppose to do at this point?   

I need help or another product.

Last night 3 out of 7 backup jobs failed.

[ESabo]

Still working with support on this.

After a waste of a day yesterday this morning - I finally got to speak with someone.

We ran the following on every server involved - "Netsh int ip set chimney DISABLED"  -  three of the remote servers did not have this set.

So at least we are getting somewhere.

[ESabo]

Still working with support on this.   No progress whatsoever.

They had me reboot three servers, that still didn't help.

Last night - 3 out of 7 jobs failed

Tonight - 3 out of 7 jobs failed again.

Why is backups so hard?

[ESabo]

We made some progress, we changed the ports that the remote agent talks on to 40,000 and 60,000.   Then we followed symantec doc # 255498

I will keep everyone posted.    Two days now without a failure.

Is this still working for you?

I have had the same issue trying to backup Exchange 2007 using the remote agent.  I can backup the Outlook Address Books and the Resources but cannot backup the Information Stores -  no how, no way.

Thanks in advance
