A disk file of this type consists of a virtual disk descriptor file and paired delta extent file. These data files are based on the vmfsSparse format, intended to store delta content or "change data" for a period of time, otherwise known as a snapshot.
Notes:
To recreate a missing virtual disk (VMDK) descriptor file for delta disks:
Base disk descriptor file examplevm.vmdk | Recreated delta descriptor examplevm-000001.vmdk (originally copied from examplevm.vmdk) |
