We just upgraded one of our ESX from 3.5 to 4.1. To backup our VM we use a script within the COS to snapshot VMs before sending VM data to TSM.
On the ESX 4.1 host we have an issue when sending the flat.vmdk file. It seems that the vmdk is still used by a process despite the snapshot.
If we migrate the VM to an ESX 3.5 host, the backup works well
thanks in advance
