A standard VMDK consists of two parts: a small text descriptor file (which defines the geometry, adapter type, and parent linkage) and a large binary data file (the actual storage). In a snapshot scenario, the base VMDK becomes read-only, and a new delta file is created to capture all subsequent writes.
Manual cleanup of a datastore directory accidentally removes active -00000x-delta.vmdk files. Step 1: Map the Snapshot Chain Structure Help restoring VM from flat and delta .vmdk files delta vmdk recovery
If the small .vmdk descriptor file is deleted but the large -delta.vmdk exists, the VM will fail to power on. : You must manually recreate the descriptor file. A standard VMDK consists of two parts: a
For partial recovery (only changed blocks since snapshot): the base VMDK becomes read-only
