Unable to obtain backup status from vProxy after 5 attempts

Hello guys,

Some backups are failing with the following error :

164541 10/01/2017 03:37:45 AM  nsrvproxy_save NSR error "vmname": Unable to obtain backup status from vProxy after 5 attempts, failing the backup: Received an HTTP code: 404, libCURL message: "Operation timed out after 1800618 milliseconds with 0 out of -1 bytes received", vProxy message: "Error received from vProxy ="-404: Resource not found: c92f57e4-8c25-4cc4-a081-562b8c39e4dd".

Looks like it's a timeout issue but the vProxy is not overloaded and is handling other backups successfully.

In this config, i have :

3 vProxys for around 150 VMs

Max 30 VMs per group

Parallelism set to 15

timeout set to 60

1 hour delay between each VMs group

Any idea what could cause this ?

thanks

Julien

Re: Unable to obtain backup status from vProxy after 5 attempts

Hi,

Please check if the VM is in "Orphaned state or powered off". Also if VM has been vMotioned to any other host or datastore.

Thanks,

Re: Unable to obtain backup status from vProxy after 5 attempts

Hi,

all the VMs are up and running.

Some of them may have been moved to a new datastore but only once, not every day

thanks,

Re: Unable to obtain backup status from vProxy after 5 attempts

Hi,

has this problem been resolved?

I get similar errors during VM backups.
NetWorker v9.2.1.0 Build163
8 x vProxies v2.1.1-41_1
1 x Data Domain DD9300 v6.1.2.5-595467 +ECS

Like you mentioned the proxies are working fine. Other backups are done perfectly.
I have one policy/group with 220 VM's and there are:

- 3 with this cancelled error
- 8 others showing hard disk info (closin, queued, percentages)
   Although these are shown as failed, in the logs they are successful and I can even
   select them for restore without any problems
- 3 others with "Unable to backup virtual disk "Hard disk 2""

regards

Re: Unable to obtain backup status from vProxy after 5 attempts

Hello,

Yes this issue has been resolved with some tuning.

what are your parallelism and inactivity timeout settings for vmware

policies ?

thanks,

Julien

Re: Unable to obtain backup status from vProxy after 5 attempts

For most actions in the principal VM policy (hotadd) we have 25 parallellism and 30 for inactivity timeout.

For a special nbd policy it's 10 parallellism and 30 for inactivity timeout.

Re: Unable to obtain backup status from vProxy after 5 attempts

Hi, 

We are having the same issues.  Issue started off a back of restoring vms to a different data store due to an SRM failure.  Since the restores, we have been getting these type of errors during backups.

I have been also told that the vms contlunally move from data store to data store. ??

Can you explain the relation of the error if the vm have been moved to another host or datastore?
