This article contains information on how to allow/deny shadowing of the specific file types.
Before you can use Content-Aware Rules for shadow copy operations, you must turn on shadowing in Auditing and Shadowing at the device type-level, e.g. Removable.Content-Aware Rules that apply to shadow copy operations filter the shadow copies of files written by the user.
*Note: Generic shadowing rights specified for the Removable device type apply to unencrypted devices only. Encrypted shadowing rights specified for the Removable device type apply only to encrypted devices. To specify shadowing rights for both encrypted and unencrypted Removable devices, you must specify both Generic and Encrypted shadowing rights.
