Creating snapshot Error-The operation is not allowed in the current state

Hi All,

Am using the Veeam Backup & Recovery 6 Software to replicate a LIVE VM (VM 1).But am unable & I got the following error:

Creating snapshot Error-The operation is not allowed in the current state

The above VM can only be copied when it is SHUTDOWN  The VM is running on ESXi 4.0.

I have one more LIVE VM (VM 2) on this ESXi host which I was able to replicate successfully to another ESXi host.

I contacted Veeam Support before posting here.

Things to note about VM 1: I cannot take a snapshot manually from the vSphere client.This option is greyed (disabled) on VM1.. while its OK on VM2.

Veeam Support told me that since its software uses the snapshot feature of ESXi & that feature is disabled, the replication cannot proceed.

Thanks to help me on this.
