What Is Incremental Backup & Differential Backup?

Windows 7 incremental backup is no more strange to us. As time goes by, there are more and more important files and programs on the computer. We may be reminded to backup system after installing it so that we can directly restore system when we change our PC or when the PC has some troubles.

However, what about the data created between the system backup and the next recovery? Backup system again? There’s no doubt that it will take much time and space. To solve this problem, incremental backup and differential backup come out and they are very effective.

Incremental Backup

Incremental backup, as its name refers, is only backing up the added or changed files. Incremental backup is on the basis of the last backup or the first full backup, which means each backup’s image file is based on the last image file, so all the image files are related together. If you delete a previous image, all the subsequent image files will be invalid.

Differential Backup

Different from incremental backup, differential backup is backing up the data based on the last full backup. It can improve the backup speed and reduce the storage space efficiently.

Best Free Incremental Backup Software for Windows 7/8/10/11

Although we can backup data with the built-in Windows 7 Backup and Restore, we may worry about the increasing data’s safety and the big image created by Windows built-in backup tool which will take up large storage space. To ensure the data is safe and save more space for disk, we can find third party software to make an incremental backup.

I usually use free backup software like AOMEI Backupper Standard for its abundant features and it can keep the data safe. What’s most important, it costs no money.

  • You can create system backup, disk backup, partition backup and file backup as per your need.
  • You are able to set up unattended backup so as to backup changed data without human intervention.
  • There are three backup methods offered: full/incremental/differential backup. The differential backup method is available after upgrading to higher editions.
  • All Windows PC operating systems are supported, including Windows 11, 10, 8.1/8, 7, Vista and XP.

It can be the best free software to make an incremental backup. Well then, how to make Windows 7 incremental backup with this free backup software? Let me explain to you in the next part.

Step 4. After clicking the “Finish”, we have already made a full backup. Then, we can go to the Home tab, and choose the “Incremental Backup” under the “Backup” item, and it will go to the execution page to do the incremental backup automatically.

Choose Incremental Backup

After the incremental backup has been finished, you can view all the backup tasks by clicking the “Properties” > “Versions”. You can see the incremental backup task clearly.



AOMEI Backupper can ensure the data is safe, so when you use this software, don’t worry about it. The operation steps to perform differential backup are similar. You can see more details from Incremental vs. Differential Backup.
