Hello
I've searched for how to delete specific backups that I've created using the elevated Power Shell command "wbAdmin start backup -backupTarget:E: -include:C: -allCritical -quiet" but I've run into a roadblock.
The problem is that none of the "wbadmin delete xxx" commands are actually supported in Win8.1 Pro 64-bit (6.3, Build 9600). If I type "wbadmin delete /?", I get:
---- Commands Supported ----
DELETE CATALOG -- Deletes the backup catalog.
DELETE SYSTEMSTATEBACKUP -- Deletes one or more system state backups.
DELETE BACKUP -- Deletes one or more backups.
However, when I try to use ANY delete command (for example, to delete a specific backup version that was identified using "Wbadmin get versions"), I get this error:
PS C:\WINDOWS\system32> wbadmin delete backup -version:06/26/2014-07:29
wbadmin 1.0 - Backup command-line tool

Warning: The DELETE BACKUP command is not supported in this version of Windows.
The operation ended before completion.
The same thing happens if I use -deleteOldest, with or without the -backupTarget switch.
Does anyone know why the Delete command is not available on 8.1? Is there a patch, workaround or alternate method of deleting specific backup images?
