as you are using the cluser name to backup the K Drive, can you make sure that the Both cluster resources  K drive and Cluster IP are in Same Note.

some times it happens like K drive will be in one node and Cluster IP will failover to another node which leads to issue.

what is the backup selection for this cluster  policy ?

Hello Nagalla,

Thanks for you reply, Basically there are 3 IPs.

1 IP is for Virtual Cluster Name and 2 IPs are for their respective Nodes.

So here I have configured Cluster nodes in one policy with Backup Selection of "C:\ and System State,"
and Virtual Cluster in one policy with Backup Selection of "K:\"

I believe It has to do somthing from Client side, Please advise.

hi,

please try below.. 

1) make sure that you dont have any old Shadow copy images in client side

Vssadmin list shadows

if you find any old shadow copies , delete those,

2) make sure your  Shadow copies size is set to No limite in Drive Properites.

3)In the master server Properties select disable snapshot and continue.

 Host Properties -> Master -> Client Attributes -> <client name>

if you dont fine Client Name , add it and then select the option disable snapshot and continue.
