In addition, the biggest change is that it adds a new backup setting - Back up files to OneDrive. Thus, you can use all the Windows 10 backup utilities in Windows 11 to backup your files, system, partition or disk. Below is the comparison chart of them:

And you need to create a factory image of Windows 11 after upgrading so as to restore computer to factory settings in case of unexpected errors. Here I'll show you how to backup Windows 11 with the best free backup software – AOMEI Backupper Standard. First, let’s take a closer look at its backup features:

All-in-one backup software: It supports backing up system, disk, files or folder, partition separately. If you upgrade to higher editions, you can also backup important emails, such as Gmail, Outlook Mail, and Yahoo Mail.

Incremental backup: It's the default backup method and backup only changed files since the last backup, whether it's a full backup or incremental backup. Besides, it still supports differential backup in the professional version. For differences between them, check: Incremental or Differential Backup.

Other useful features: It is capable of compressing image, splitting image automatically, notifying backup status, creating bootable USB or CD/DVD to boot computer when it fails, etc.

AOMEI Backupper

Best free Windows backup software for personal use.

Windows 11/10/8.1/8/7

 (The following steps apply to Windows 10/8/7/XP/Vista as well. And all the steps are exactly the same. For server users, try AOMEI Backupper Server.)

Step 1. Launch AOMEI Backupper Standard and click "System Backup" under the "Backup" tab.

Notes:

• If you only want to backup important files that will not occupy too much disk space, choose File Backup. If all of them on a specific partition, choose Partition Backup.
• If you want to backup disk with all the data on it, including the operating system, installed program, personal data etc, choose Disk Backup.

Step 2. Then, it will select Windows 11 system partition and other partitions required to boot Windows by default. Click the box in the lower location and select external hard drive as backup destination.

Step 3. After selecting backup destination, click Start Backup to backup Windows 11. Wait until the process is complete, and you will have an exact copy of your system at the moment you back it up.

For continuous backup

The backup you created with the above 3 steps will not include changes made later. To protect it continuously, if you want, click Schedule Backup > Enable Schedule Backup, choose Daily, Weekly, or Monthly. And it is usually performed with incremental backup in the Backup Scheme to backup only changed files.

In addition, you still can use the other two options in the advanced version, namely, Event trigger and USB plug in (to backup computer to USB flash drive automatically when it's plugged in) feature.

Now, this software will create a complete system backup first and then create 6 incremental backups, and repeat the process. This may result in another issue - backup disk full, and at this moment, you cannot backup any items unless you delete some of them.

However, you may delete the backup mistake, resulting in all the backup invalid. The incremental backup requires all the backup to be intact while recovery. Based on this consideration, you can change incremental backup to differential backup (supported by the professional version), which only requires one full backup and any differential backup. 

Besides, you can choose to enable cleanup methods (By quantity, By time, By daily/weekly/monthly) and delete old backup image automatically. And you ensure there is always enough space to keep new backup image.

In addition, if you want to get the backup result timely, you can enable Email notification in the Options. Also, you can change compression level to High, customize the splitting size, password protect backup image(upgrade is required.), etc. 

For WinPE backup

Sometimes, you may intend to backup system without Windows due to different reasons. You can choose to create a bootable meida with USB or CD/DVD and make a recovery environment in advance. The latter is to add boot menu on the current computer, so it does not require any device to store boot files.

You just need to restart your computer and then you will see an option like Enter into AOMEI Backupper. Select it and you will see the main page AOMEI Backupper Standard just as in Step 1. Then, you can backup system without booting into Windows or perform offline restore if you want.

Wrapping things up

This page offers you the best 5 Windows 11 free backup software. If you prefer built-in backup software, try Backup and Restore (Windows 7), File History or OneDrive. If you want more potent backup programs, pick AOMEI Backupper Standard or AOMEI Cyber Backup.
