This policy setting allows users to circumvent file and directory permissions to back up the system. This user right is enabled only when an application (such as NTBACKUP) attempts to access a file or directory through the NTFS file system backup application programming interface (API). Otherwise, the assigned file and directory permissions apply. The recommended state for this setting is: Administrators. Note: This user right is considered a 'sensitive privilege' for the purposes of auditing. Rationale: Users who are able to back up data from a computer could take the backup media to a non-domain computer on which they have administrative privileges and restore the data. They could take ownership of the files and view any unencrypted data that is contained within the backup set. Impact: Changes in the membership of the groups that have the Back up files and directories user right could limit the abilities of users who are assigned to specific administrative roles in your environment. You should confirm that authorized backup administrators are still able to perform backup operations.
To establish the recommended configuration, set the following Device Configuration Policy to Administrators: To access the Device Configuration Policy from the Intune Home page: Click Devices Click Configuration profiles Click Create profile Select the platform (Windows 10 and later) Select the profile (Custom) Click Create Enter a Name Click Next Configure the following Setting Name: <Enter name> Description: <Enter Description> OMA-URI: ./Device/Vendor/MSFT/Policy/Config/UserRights/BackupFilesAndDirectories Data type: String Value: Administrators Note: When there is more than one value that needs to be entered (ex: Guests, Administrator), the XML value of will need to be converted to US-ASCII to separate the values in the Value field of the Custom Device Configuration Policy. This value should convert to a square with a question mark in it (). Please note that when copied from the converter to Intune a square will appear, but the value will still work. Also note that this value cannot be copied from sources like Microsoft Word. We recommend that the value be copied and used directly from the converter. Select OK Continue through the Wizard to complete the creation of the profile (profile assignments, applicability etc.) Note #2: More than one configuration setting from each of the Configuration profiles (ex: Administrative Templates, Custom etc.) can be added to each Device Configuration Policy. Note #3: The following link is an alternative way to set the 'User Rights Assignment' section.
