Hyper-V image level backup issue

Hyper-V image level backup issue

Hi All,

I'm trying to take an image level backup on Hyper-V nutanix by Networker (EMC backup appliance).

It succeeds to backup the VM but fails to backup the config files and the below error shows up (Most probably it is a nutanix access issue):

=============================================

suppressed 3077 bytes of output.
Creating files/directories on container template for VC_FS_MPATH_MFILES backup.

Re: Hyper-V image level backup issue

Pierre - Thanks for reaching out both here and on direct message. Note that you did have a duplicate post on here, so I've deleted that to concentrate responses here.

 

If this is extremely urgent, please file a support ticket on portal.nutanix.com if this is NX or SX gear, or with your respective OEM if this is XC (Dell) or HX (Lenovo) equipment and we can help you out.

 

I'd also recommend opening a ticket with EMC to get their NetWorker support to start looking at this issue.

 

Note that the community forums are not designed for any sort of SLA, so if this is truly urgent, please drive this through support as I mentioned above.

Re: Hyper-V image level backup issue

Hi,

Did you find the resolution of this issue, we are facing exactly the same problem

Thanks

Re: Hyper-V image level backup issue

We have the same problem. From what I understand, the problem seems to be with node changes. When a VM node change occurs, most backup solutions do not know what to do with it. It either ends in a Backup failure or VM corruption. Nutanix has released APIs for AHV but that is all. More are on the way from what I hear. Until then, I am still trying to find a stable backup solution.. Very scary. 

Re: Hyper-V image level backup issue

Hi Gary,

I have already fixed the issue and everything is working fine now.

Networker 9.1/Hyper-V over Nutanix SMB.

 

Let me know if you still need any assistance.

 

Best regards,

Pierre
