Welcome to the Commnutiy..
Which version of ESXi/vCenter are you running?
What is the backup software used?
Are youe getting this when doing a Full VM restore?
the version of esxi and vcenter are 4.1.0 and i install a vmware data recovery in my context.
i backup full system file at 18:00 everyday and keep them for 1 week
today i restore one of them, then the error comes. though the restore process completed, i still want to know why?
is there something wrong with my memory?
