flat *.vmdk file needs full diskspace after uploading form datastore
I have a VM with a flat vmdk File ("Filename.vmdk" / Full HD space 40 GB / used space in datastore 23 GB) on my ESX Host (Version 5.5)
For a backup of the full VM I uploaded the full folder from the datastore to my backup server (Windows Server 2012). I used vSphere Client 5.5.
On the Backupserver I finde the VMDK two vmdk files:
- Filename.vmdk with 1KB
- Filename-flat.vmdk wiht 41 GB !!!
Why did my flat VMDK File grow to the full space by uploading form the datastore? What can I do to not have this effect?
