Back Up Your NTFS Security permissions

To Reset NTFS permissions, the most common way is using ICACLS command line. It's the replacement for cacls (Change Access Control Lists), and allows you to define who and how users access filesystem objects. Besides, you still have the ability to backup and restore NTFS permission and reset its to default permission or inherit from the parent folders if the NTFS permissions mess.

Back up your NTFS security permissions

1. Run AOMEI Backupper Professional on your Windows machine. Go to the Backup tab and select File Backup. Click Add Files or Add Folders to select the data you want to backup. After that, select a destination path and click Start Backup to backup files with NTFS permissions.

2. To restore NTFS permission, switch to the Restore tab and choose Select Task. Then, you will see all your backups and choose the file backup in the given list and click Next. If it is not listed, click Select Image File to browse manually.

5. Click the Setting icon at the lower left corner, tick "Restore NTFS Permissions" and hit "OK". At last, back to the main page and click "Start Restore" to restore files with NTFS permissions.

If your files with NTFS permission mess, you can try above methods to reset NTFS permissions to default. To be sure your files are always safe, it's recommended to keep AOMEI Backupper Standard and backup files to external hard drive regularly. So no matter you lose the permission or it's damaged, you can easily get it back.

Before making significant changes to permissions (move, update ACLs, migrate resources) on an NTFS folder (or shared network folder), it is advisable to back up the old permissions. This copy will allow you to return to the original settings, or at least clarify the old permissions for a specific file/directory.

Open the file veteran_ntfs_perms.txt using any text editor. As you can see, it contains the full list of files and folders in a directory, and each item has the current permissions specified in SDDL (Security Descriptor Definition Language) format.

You can restore NTFS permissions on a folder using the previously created veteran_ntfs_perms.txt file. To set NTFS permissions on objects in the directory according to the values in the ACL backup file, run this command:

This is very helpful. If I make a duplicate of the g:\veteran onto a new drive, say e:\veteran, and mess up my permissions on the e:\veteran version, is it possible to use the g:\veteran backup to restore on e:\veteran? Do I need to do something to change the ACL file to point to the new location and restore permissions there?

You can use powershell to list subfolders and export their permissions to files:$folders= Get-ChildItem -Path C:\PS -Recurse -Directory -Force -ErrorAction SilentlyContinueforeach ($folder in $folders)icacls $folder.FullName /save c:\backup\$folder /c

From time to time we are asked how to backup and restore NTFS file system permissions as well as network share permissions. KB article 125996 talks about the network share piece of it, but it does not talk about NTFS permissions. One thing that has made the NTFS permissions piece of this simpler is the Icacls tool. Icacls was developed for Windows Vista as a replacement for tools such as Cacls , Xcacls , and Xcacls.vbs . It was also included in Service Pack 2 for Windows Server 2003 and Windows Server 2008. Backup and Restore of Share Permissions To backup share permissions, export the Shares registry key.

drive-or-folder is the name of the drive or folder whose permissions you are saving; to back up the ACL (Access Control List) for an entire drive, you must specify the drive name with a double slash (for example, drive C: appears as "C:\")

NTFSBKP stores security information by name, not by SID (Security Identifier). Suppose you have a folder with permissions explicitly set for User A. If you back up these folder permissions, and then you delete User A, the restore operation will not restore User A's permissions. However, if you create a new account (different SID) with the same name (User A), that account will be used as the permissions-holder for the restore operation on that folder.Maps the hash to the security descriptor's storage location within the $SDS data attribute.

Previously, MSP360 Backup did not retain NTFS security permissions when performing data backup. From now on, you can back up and restore your files, folders and network shares with the complete set of their NTFS permissions.

Note: In the Backup Storage section, you can find only the actual backed up files and folders. It does not display NTFS permissions of those objects. You can find these NTFS permissions displayed in the History tab.

Note: The NTFS permissions are kept within the file version. If you modify NTFS permissions for the file but do not modify the file itself then the next backup iteration will back up only the updated permissions for that file. So, during the restore process, that file will be restored with the latest set of its NTFS permissions.

With the latest version of MSP360 Backup solution, you don't have to worry about saving the NTFS permissions for your data. You can back up your files retaining all their NTFS permissions and easily restore them back to any location with the same set of permissions. Additionally, you can back up and restore NTFS permissions only, without the files they are assigned to which is an especially useful feature for server administrators.

Actually, operations on ACL are not the only ones possible with this tool.What makes it a powerful tool is also the ability to perform backup and restore operations on ACL for files or directories, or to search for files that have a specific user as owner.And in addition, in the event that an ACL is damaged or destroyed, with icacls you can restore it by resetting it and setting default permissions or inheriting those of the parent.

When restoring NTFS permissions, those permissions can only be restored successfully if the Backup Agent is running on a computer within the same domain as the one backed up. Also, the software will restore the NTFS permissions for files, but not folders; to see whether or not permissions are restored, you will need to check the files restored as folders created by the Backup Agent will have default permissions.

The account that runs the VisualSVN Background Job Service should have appropriate permissions to the backup destination. Required permissions differ depending on whether your backup destination is on a local disk or on a network share. See the corresponding sections below for more information.

By default, VisualSVN Background Job Service runs under the built-in NT AUTHORITY\Network Service account. Services that log on and run as NT AUTHORITY\Network Service account access network resources using the credentials of the computer account (for example, DOMAIN\Computer$). If you plan to use a network share as the backup destination, you should provide the server's computer account with NTFS and share permissions to the backup destination.

You should properly configure your VisualSVN Server instance for using Azure Files cloud as a backup destination. For details and complete instructions see the article KB133: Storing repository backups in the Azure Files cloud storage

In Microsoft Windows 2000, in Windows Server 2003, and in Windows XP, you have the option of using either the FAT32 file system or the NTFS file system. When you use NTFS, you can grant permissions to your folders and files to control access to those objects. When you copy or move a file or folder on an NTFS volume, how Windows Explorer handles the permissions on the object varies, depending on whether the object is copied or moved within the same NTFS volume or to a different volume.

Datto SIRIS offers a variety of backup and restore types to meet different recovery scenarios. One of these is known as File Restore with NTFS Permissions. It is specifically designed to restore an externally-hosted NAS share its file permissions intact.

To perform this type of restore, you must first back up a NAS share with NTFS permissions intact. This enables the contents of the selected recovery point to be shared over your network as an iSCSI target. Upon restore, all files and folders in the recovery point will include the ACL attributes (read: permissions) they had at the time of the snapshot.

With the additional functionality that is provided by the NTFS permissions, its configuration is very complex that can lead to administration headaches. While managing your permissions on the top-level directories sometimes goes inaccurate, and this inaccuracy will force the sub-directories to change, which causes issues.So, to avoid this kind of situation, it is always recommended to backup folder permissions before making any changes to the NTFS or sharing settings. If anything bad happens, you can actually restore the back up to its original configuration without any loss.

To backup share permissions, export the Shares registry key.Open Regedit to the following locationHKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\SharesRight-click the Shares registry key and select Export. Give it a file name such as share-permissions-folder.reg.if(typeof ez_ad_units!='undefined')ez_ad_units.push([[300,250],'itechtics_com-leader-1','ezslot_11',190,'0','0']);__ez_fad_position('div-gpt-ad-itechtics_com-leader-1-0');Restore Folder PermissionsWhen you want to restore the permissions, double-click share-permissions-folder.reg (This registry will be located at the location, where you have exported) to import it back into the registry.
