Windows does not allow creating VSS shadow copy on removable USB flash disk, why?

1

I formatted a 16GB USB flash disk to NTFS and tried to make it VSS available, but failed. I tried to do it on a Windows Server 2008 R2 machine, running

vssadmin create shadow /for=e:

and I got error:

Error: The given shadow copy provider does not support shadow copying the specified volume.

Can some one tell me why it is not allowed? I thought the only requirement is using NTFS on the volume(partition).

Obviously you were mistaken about the requirement. There is a great deal that Windows does not like putting on removable devices. – Ramhound – 2015-07-10T13:18:22.550

There are ways to make an external removable flash drive, appear not to be removable to Windows, you could try doing that. I wouldn't because I suspect there is a good reason this isn't supported. – Ramhound – 2015-07-10T16:12:28.867
