Hi everyone,
I am hoping that someone can help me out here. I have a 2 node 2012 R2 Hyper-V Failover Cluster, and I am trying to get our Veeam backups to work on this Cluster. On node 1 the backups work fine with no issues, but on node 2 the Veeam jobs constantly fail with the following error:
10/09/2015 14:39:23 :: Unable to create snapshot (Microsoft CSV Shadow Copy Provider) (mode: Veeam application-aware processing with failover). Details: Failed to check whether provider '{400a2ff4-5eb1-44b0-8a05-1fcac0bcf9ff}' supports shadow copies on the volume '\\?\Volume{d8496e1b-cf0c-4cf4-8554-0afd39f67e5d}\'.The volume shadow copy provider is not registered in the system.--tr:Failed to add volumes to the snapshot set.--tr:Failed to perform pre-backup tasks.
On the node where the backups are failing, issuing the command to list the providers only shows the following providers:C:\Windows\system32>vssadmin list providers
vssadmin 1.1 - Volume Shadow Copy Service administrative command-line tool
(C) Copyright 2001-2013 Microsoft Corp.
Provider name: 'Microsoft CSV Shadow Copy Helper Provider'
Provider type: Software
Provider Id: {26d02d81-6aac-4275-8504-b9c6edc5261d}
Version: 1.0.0.1
Provider name: 'Microsoft File Share Shadow Copy provider'
Provider type: Fileshare
Provider Id: {89300202-3cec-4981-9171-19f59559e0f2}
Version: 1.0.0.1
Provider name: 'Microsoft Software Shadow Copy provider 1.0'
Provider type: System
Provider Id: {b5946137-7b9f-4925-af80-51abd60b20d5}
Version: 1.0.0.7
But for some reason on the working node, it lists the above providers along with the additional provider that Veeam is expecting:
Provider name: 'Microsoft CSV Shadow Copy Provider'
Provider type: Software
Provider Id: {400a2ff4-5eb1-44b0-8a05-1fcac0bcf9ff}
Version: 1.0.0.1
I could really do with knowing why node 2 is missing this provider, and how I can get it installed so that I can get the backups to work. The Cluster Nodes were both built at the same time using the same configuration, so why this is missing is a mystery to me!
Any help anyone can give me is greatly appreciated.
Many thanks.
