Hi!
I don't think so - I tried to clone VM to the same storage (block size 4, max file 1024GB), VM has thin disk 500Gb (only 50GB used), with Veeam I tried to backup this VM to storage appliance (Data domain 620) and then I tried to copy VM (again via Veeam). All without result.
Also, our data-store connected by FC - no NFS...
