Creating redo file for managed disk in ESX Server using VDDK

Hi,

I am looking for a way to backup VM disk files of the ESX Server using VDDK (without using VI SDK or VCB). I have few questions or doubt related to VDDK.

1. Is it possible to create child disk for a parent disk (Managed) available in ESX Server using VDDK, looking like its not possible directly ?

2. How the unlink function works, does it commits the data changes to the parent disk?

3. Is it feasible to create hosted vmdk disk, clone it to a remote ESX server and convert it to managed disk, then attach it to the parent disk?

4. In case 3 is it possible to commit the changes of the attached disk to the parent disk using unlink function ?

Can any one help me to get the doubts clarified?

Thanks in advance,

Muthu

To achieve what you looking to do, VI api's need to be used in conjunction with VDDK. To answer your questions:

1, No - If you are looking for a way create a snapshot of the VM, you can use the VI api

2. No - these operations should be at snapshot level (create / delete snapshots, which do what you expect)

3. You can create hosted vmdk, clone / convert to a managed disk and perhaps attach to a VM - it is not possible to convert into a child - you can open the source (child) disk and write to the destination (child) disk.
