When we are operating our Windows 10 NAS, if we want to reset system due to system display abnormal or slow, we can use the PDM interface system backup function.
Create a system backup first then restore the system if you need on the Windows 10 NAS desktop.
Moreover, system backup function can also restore all the PDM users and groups to the backup timing status.
So we highly recommend that Windows 10 NAS user should do the system backup after creating all the users and groups to avoid any system data loss.
For more information, please refer to the following system backup and restore introduction.
System Backup
1. Log in to ITE2 NAS PDM interface, select [Settings> System Management]
2. Click [System Backup] and click [Create a System Image Backup] icon. Then you should see the notification that shows system image backup is in progress. 
The system backup is running in the background; you can leave this page and do other PDM operation at any time.
3. When the backup process completed, you can see the system image backup log record. (Note: if PDM do not have any backup record after 1 hours, please refresh the page and recheck the backup log).
4. Then we can go to Windows 10 NAS desktop D drive and see a folder named WindowsImageBackup. Enter that folder, and you should see a folder named by your NAS, and this is the folder that contains your NAS system backup record files.
System Restore
Then, we will restore NAS system back to the timing we have saved.
Note: this post and demo will only restore system drive (C drive), not data drive (D drive).
1. Confirm all the desktop files and delete some data.
2. Let’s start restoring system image backup file, click Windows list and select [Settings> Update & Security].
3. In [Update & Security], choose recovery and click [Advanced startup> Restart now] icon, then the system will restart automatically.
4. After the restart, the recovery process should start, in this screen, select [Troubleshoot>Advanced options].
5. Click [System Image Recovery], and it should restart PC automatically.
6. Select your admin account (Demo account: cocosenor) then enter the admin password.
7. Select [Use the latest available system image] and click [Next].
(Note: Default settings will select the latest available system image, but you can choose to select the particular system image if you need).
8. In the pop-up window, click [Next] and make sure the system image file time and date are all correct, then click [Finish].
9. Press [Yes] and all the system data should return to the status when we have backed up.
After restore process completed, restart your Windows 10 NAS, and you can see all the desktop files are back to the original place.
