Backing up Data to Online Storage

If saved data is updated, it is automatically saved to the PSN server when you log out. By saving it to online storage, you can download saved data to another PS4 system and continue playing a game. To use this feature, you must subscribe to PlayStationPlus.

You can specify for each game whether to turn on or turn off automatic uploading, and also manually upload saved data by selecting the saved data and then selecting [Upload]. Before using the automatic upload feature, you need to do the following:

Activate the system as your primary PS4 system.

Set a check mark in (Settings) > [Power Save Settings] > [Set Functions Available in Standby Mode] > [Connect to the Internet].
Set a check mark in (Settings) > [System] > [Automatic Downloads and Uploads] > [Enable Automatic Downloads and Uploads].
Additional Information:

The maximum storage capacity that can be used with online storage is 1 GB, and the maximum number of saved data items that can be stored is 1,000.
You can check the progress of uploads under (Notifications) > [Uploads].
