How to backup ntfs/share permissions on the file server.

Backup and Restore of Share Permissions

To backup share permissions, export the Shares registry key.

1. Open Regedit to the following location:
   
   HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Shares
2. Right-click the Shares registry key and select Export. Give it a file name such as shareperms.reg.

When you want to restore the permissions, double-click shareperms.reg to import it back into the registry.
Use the Reg tool to backup the registry key from the command line:
reg export HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Shares shareperms.reg

To restore:

reg import shareperms.reg


Backup and Restore of NTFS Permissions

Use this command to backup NTFS permissions:

icacls d:\data /save ntfsperms.txt /t /c

The /T switch allows it to get subfolder permissions too. The /C switch allows it to continue even if errors are encountered (although errors will still be displayed).

Use this command to restore them:

icacls d:\ /restore ntfsperms.txt
