MY VM is of windows 2012 with dive of 200 GB and D drive of 2TB - both are on Thin provisioning. My Back up application gives a error of ..

Error: VSSControl: -2147212529 Backup job failed. Discovery phase failed. Cannot add volumes to the snapshot set. Cannot add a volume to the snapshot set. Volume name: [\\?\Volume{bb495037-d09b-11e2-93e8-806e6f6e6963}\]. Cannot add volume to the set of volumes that should be shadowed. VSS error: VSS_E_UNEXPECTED_PROVIDER_ERROR. Code:0x8004230f

and


Creating VM snapshot
Error: File <unspecified filename> is larger than the maximum size supported by datastore '<unspecified datastore>


after googling found the size of VM needs to below 2 TB foe the snapshot to make work.

can you please help to reduce the size of VM so that i can take the backup.

The only supported method of shrinking a virtual machine disk is to use VMware vCenter Converter Standalone, and complete a V2V, you can then specify the new size of the D Drive, and the conversion process will change the size of the virtual machine disk, and also the OS Partition in one procedure.

see my EE Articles

OR, add a new disk of size xTB, and perform a copy operation/robocopy in the VM, or use a Cloning tool.

You will have to clone or copy the data to a new disk. Make sure the smaller disk is less than 2TB.

I can give a try on this but the problem I see only is the down time on file server which is very critical in our business. Cannot afford.

so use robocopy with the mirror function, and it will sync changes across disks. and when you have all the files and changes on another disk, switch to that disk permanently.

all 2TB of files cannot be all access concurrently/
