Best Real-Time Backup Software for Windows 10/11 [2025]

What is a Real-Time Backup and How to Use It

Real-time backup, also known as continuous backup or continuous data protection (CDP), is an advanced way to automatically save a copy of each change when it's made. In the long term, it will capture multiple versions of the data.

Conventionally, your data can only be restored to the point at which the backup was done. But with real-time backup, once the data is written to your disk, it is written to the destination directory as well. So, does Microsoft Windows have a real-time backup program?

The answer is no. Even though Windows operating systems such as Windows 10, and Windows 11 have built-in backup utilities, there has never been a true real-time backup solution. You can use Window Backup and Restore or File History to create a scheduled backup. Although it is continuous backup software, this method is still not a true CDP.

In the following cases, it is still recommended to use professional real-time backup software:

• Working on a project with someone and need both parties to see the latest version of certain files
• Want to always keep an up-to-date copy of important data as a double insurance...

How to Create Real-Time Backup in Windows 10 Step-by-Step

After you download and install the real-time backup software AOMEI Backupper Professional, it's easy to create a continuous backup job that will automatically capture the changed data.

How to use the real-time backup software for auto sync:

1. Launch the real-time backup software. Select Real-Time Sync under the Sync tab.

You can also sync files with the schedule when you use different sync methods, such as, daily, weekly, monthly, etc.
✔ Basic Sync: It is to sync files from source to destination and supports all the schedule settings.
✔ Mirror Sync: Similar to Basic Sync, but more concerned with synced files in the destination path. It will undo any changes directly made in the destination, either newly added, modified, or deleted files.
✔ Two-Way Sync: Unlike the previous two sync methods, it will sync changes between the source and destination path. Any changes made on one of the sides will be synced to the other side.

2. Click Add Folder to select one or multiple folders you want to sync, and then select a destination path. You can edit the Task Name to make it easy to distinguish.

You can also click the funnel icon (eg: Filter settings) to exclude or include file extensions you want to sync, thereby saving sync time and space.

3. Click Start Sync to do real-time sync to keep all the data up to date. You can also leave a comment for the backup, verify the integrity of files in the destination directory, or automatically create a folder with the same name as the task in the target location.
