Quiesced backup of a VM fails with 3201 error similar to :
Error Message: 3201 - can't open [Datastore_1] VM1/VM1.vmdk
SnapShot file '[VMFS_01] Z-VError Message: 3201 - can't open [VMFS_01] VM1/VM1.vmdk - VM1/VM1-000002.vmdk' - not found in current machine state.
This is an issue with the way vRanger reads the two snapshots created by vSphere when running a quiesced snapshot using VSS
To resolve this issue try the following.
To install vzShadow on a vRanger 5.3 or previous please see SOL82417
To install vzShadow on a vRanger 5.4/5.5 please see SOL93858
To remove VSS from VMware tools please do the following.
Modify your VMware tools installations to remove VSS from it.
Once vzShadow has been installed and VSS has been removed and the VM rebooted, retry your backup.
