Data Backup by Shared Folders to Your Computer or Home NAS Devices
Did you store important data, pictures, or large files on your Phone? You can back up your data to a
computer or home NAS device by using a shared folder to prevent data loss and free up storage space
on your Phone.
Open Settings, go to System > Backup & restore > Data backup > External storage >
Shared folder, and touch Scan for shared folders. After your Phone detects PCs or NAS devices on
the same network through Wi-Fi scanning, touch to access a device and add its shared folder. Then
touch BACK UP, select the data you want to back up in Select data and touch Back up.
You can touch
the backup page, and then set a password when prompted. The password will be used when you
want to restore files later. Always remember your backup password or set security questions to
help remember the password as you will not be able to retrieve your backup files without it.
