How to Manage Windows Backup Disk Space in Windows 10

information   Information
The Backup and Restore (Windows 7) feature (aka: Windows Backup) was originally included in Windows 7. It was deprecated in Windows 8 and removed in in Windows 8.1, but has been included in Windows 10.

While you can use Backup and Restore (Windows 7) to restore any Windows 7 backups on your Windows 10 PC, you can also use it to back up and restore files on your Windows 10 PC.

Windows Backup will backup all files in the libraries, folders, and drives you choose or let Windows choose. You will have a choice to include a system image in the backup. You can also choose to have these items be backed up on a regular schedule.

After you have set up Windows Backup, you can manage how disk space is used by Windows Backup as needed. You can free up disk space by deleting previously created data file backups and system images.

This tutorial will show you how to manage how disk space is used by Windows Backup for data file backups and system images on your Windows 10 PC.

You must be signed in as an administrator to be able to manage Windows Backup disk space.

Note   Note
Data file backups are created in sets also known as backup periods.

When a backup is created the first time after you set up Windows Backup, Windows will create a full backup of all files in the folders you selected into the drive:\computer name\Backup Set YYYY-MM-DD HHMMSS\Backup Files YYYY-MM-DD HHMMSS folder location. The Backup Files YYYY-MM-DD HHMMSS folder contains Backup files #.zip folders that are your actual backed up files for that date and time period.

When you create a differential backup, it will create a new full backup saved into a new Backup Set YYYY-MM-DD HHMMSS folder.

When you create an incremental backup, it will create a backup all of the files that have changed since the last backup, and saved in a new Backup Files YYYY-MM-DD HHMMSS folder in the current Backup Set YYYY-MM-DD HHMMSS folder.

System images are saved in this format:

drive letter:\WindowsImageBackup\computer name\Backup YYYY-MM-DD HHMMSS

EXAMPLE: If your computer name is Brink-W10PC, your backup location is on hard drive (network or local) E: and you backed up on January 23rd 2017 at 5:01:54 PM (it will use 24 hour time), then your system image would be located in the folder below.

E:\WindowsImageBackup\Brink-W10PC\Backup 2017-01-23 190154

Note   Note
If you turned off the schedule for automatic backups, then you will see the left screenshot above.

If you turned on the schedule for automatic backups that include a system image, then you will see the right screenshot above. You can change the maximum space used by Windows for storing system images on a disk by adjusting the Max Usage slider for the disk (ex: "E" ) in the System Protection settings like below.
