Ensure 'Back up files and directories' is set to 'Administrators'

AltaNível 1Automatizadawindows

Descrição

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.
