Backup/Restore NTFS Security Settings


This is a very handy script that I used to backup and restore the NTFS security settings last time for a File Server migration project. If you would like to try it, all you need to do is to copy and paste the following script into a text file and rename it to NTFSBKP.bat, then download the utility ‘subinacl.exe’ from Microsoft and place it in the same folder.

********************************************

REM The syntax for using NTFSBKP.bat is: NTFSBKP DriveOrFolder DestinationFolder BKP|RST
:: Where:
:: DriveOrFolder  is the drive, or folder, including files and sub-folders, whose NTFS security you wish to backup or restore.
:: DestinationFolder  is the destination folder that will contain /does contain two files that hold backed up security attributes.
:: BKP|RST BKP causes NTFSBKP.bat to backup the NTFS security. RST causes NTFSBKP.bat to restore the NTFS security from the previous backup.
