Backup virtual machine fail - VSS Error ?

[Jor]

Hello,

I have a serious problem with virtual machine Backup on HYPER-V. All my jobs (10 VM) fails with error : V-79-57344-65078

I have checked and try all solution proposed by this page : http://www.symantec.com/business/support/index?page=answers&startover=y&question_box=V-79-57344-6507...  but nothing works. In my Windows event viewer i can see error ID : 57484

"Error the request of the extended attributes (AE) of the following file : My VHD file"

I have another HYPER-V server withtout any problem (same configuration)...

Infrastructure :

• Backup Exec : R3 without SP1
• Hyper-V host : Windows 2008 R2 64bits
• Hyper-V VM: Windows 2008 R2 64 bits

I have checked :

• Administrator account  OK : Backup fail
• VHD File OK : Backup fail
• Enable Shadow Storage Copy on different disk  OK : Backup fail
• Reschedule Backup VM OK : Backup fail
• Start one job a the same time OK : Backup fail
• Check / Uncheck : AOFO OK : Backup fail
• "Vss admin list writers : All is OK"

Can you help me about that ?

Thanks a lot !

Check that your disk is supported.  See the Hyper-V Storage Configuration Compatibility section on page 7 of the SCL.

BE 2010|2010 R2|2010 R3 Software (SCL)

My disk is supported it's a dynamic VHD, bakup jobs works at the begining...

Hi,

Have you run: vssadmin list writers from a command prompt to make sure your VSS writers are stable and running?

If they aren't a reboot of the server normally sorts this out.

Otherwise try removing the VHD and readding it.

Thanks!

Hello, Yes i run vssadmin list writers and no error. I can't just reboot my server, i'm in production environment with arround 10 virtual machines running...

It's not possible to delete VHD, like i said im in production environment...

...then you will need downtime. Altrnatively, if you don't get help here, and if you have a support contract in place with Symantec, then you can open a call with them.

There is no way to resolve this issue without rebooting the Hyper-V server ??

...not sure. It's normally a recommendation if you are experiencing VSS errors. Otherwise wait to see what you get in terms or responses on your query...
