Veeam – Error VSSControl backup job failed. Discovery phase failed<\/h5>\n

Few months ago i realized the conversion Microsoft Hyper-V cluster to VMware vSphere Cluster, after some time veeam backup started failing due to a VSSControl Error.\u00a0 \u00a0<\/p>\n

Processing XXX Error: VSSControl: -2147212529 Backup job failed. Discovery phase failed. Cannot add volumes to the snapshot set. Cannot add a volume to the snapshot set. Volume name: [\\\\?\\Volume{89ef56de-570f-43a8-8866-db5d1a4d1779}\\]. Cannot add volume to the set of volumes that should be shadowed. VSS error: VSS_E_UNEXPECTED_PROVIDER_ERROR. Code:0x8004230f<\/em>

<\/p>\n

Log in the VM and check installed VSS providers\u00a0<\/h4>\n

Open cmd as an administrator and run command „vssadmin list providers<\/strong>“ now you can see list of providers, for some reason i had „leftover provider“ – Hyper-V IC Software Shadow Copy Provider,\u00a0<\/strong>from the past, when the VM was running in the Hyper-V cluster, but now is in the vSphere.\u00a0<\/p>\n

\"\"<\/a><\/p>\n

i also checked event viewer for in the Application log – Event ID 22 and 12292, in the general tab of event, we can see the provider ID – which is associated with the Error message. If you compare the ID with Hyper-V IC Software Shadow Copy provider – the ID is identical.\u00a0<\/p>\n

\"\"<\/a><\/p>\n

The solution is remove the Hyper-V IC Software Shadow Copy Provider from registry. BUT please do a backup of entire registry key before removal !<\/strong><\/p>\n

Open the regedit and navigate to\u00a0 HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\services\\VSS\\Providers\\\u00a0<\/strong><\/p>\n

\"\"<\/a><\/p>\n

and remove the registry key.\u00a0<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

After reboot of VM run the cmd as administrator and type „vssadmin list providers“ and the „Hyper-V IC Software Shadow Copy Provider<\/strong>“ is removed. Now you can run the Veeam Backup \ud83d\ude42\u00a0<\/p>\n
