My hard disk has three partitions c:(windows10), e:(windows 8.1) and g:\storage.

When I try to create a backup of c:\ & e:\ on g:\ the backup fails because drive g:\ has its shadow storage on drive e:\ instead of on itself.

This situation was created last month because I have created backups every month for the three past years.

I used the vssadmin command from elevated command prompt but there is no way to delete the shadow storage on drive E:\ but you can only see it.

So I have to use powershell in order to use something like PS c:\windows\system32\>wmic shadowstorage delete ... but I don't know the exact syntax after the verb delete (e.g. volume=E:)

How can I resolve this?

  • there's a wmi class win32_shadowcopy you could try. (get-wmiobject win32_shadowcopy | where { $_.something -eq 'something' }).delete() as you can see i left the filter empty for yourself to fill (change $_.something to a propertyname and 'something' to a real string) so you can target the correct shadowcopy object. I don't know if that will work, but you can try. run only get-wmiobject win32_shadowcopy first to get a feeling

There is no way to delete the shadow storage on drive E:\

Actually there is.

Use the following command:

vssadmin delete shadows /for=e: /all

Vssadmin delete shadows

Syntax

vssadmin delete shadows /for=<ForVolumeSpec> [/oldest | /all | /shadow=<ShadowID>] [/quiet]

Parameters

enter image description here

Remarks

You can delete only shadow copies that have the client-accessible type.

Examples:

To delete the oldest shadow copy of volume C, type:

vssadmin delete shadows /for=c: /oldest

Source Vssadmin delete shadows
