VM backup failing after installing SF Basic on Hyper-V Core server

Hi all,

We have Hyper-V server with 10 virtual machines. We are using NetBackup 7.1.0.4 as backup software. Before installing SF Basic 6.0 , backup of all VM's was going fine. Now the backup of all VM's that are in running state is failing with error: Snapshot error encountered (156). Backup of VM's that are not running is going fine.

I've installed SF Basic on a second Hyper-V server and I got the same situation. After that I've uninstalled SF Basic from this server and all backups are working fine.

In the VEA console I can see the snapshots for the VM volumes created and after 2 minutes they are deleted. (screenshot in attacment)

This is the error in the bpfis log from the NetBackup client:

Does someone know what could be the problem? Are there any debug logs in Storage Foundation to help me with this problem and where can I enable/find them?

Hyper-V Question -> Storage Foundation for Windows Category

Hi,

In the Storage and Clustering Forums, you will see that there are two Storage Foundation categories.... "Storage Foundation", and "Storage Foundation for Windows".  The best place for your question with Hyper-V is in the "Storage Foundation for Windows" category, as this category is really intended for UNIX and Linux operating systems.
