You may want to try cloning the whole VM to another VMFS volume via vCenter or just the disks with vmkfstools -i File-Server-1_1-000002.vmdk /vmfs/volumes/NewDatastore/ -d zeroedthick (see http://kb.vmware.com/kb/1028042).
This will consolidate the snapshots on the destination too and you'd have a backup at least.
