Manage Backup Size
First click on Start and enter backup and restore in the search box and hit Enter.
Then under the Backup section click on Manage Space.
In the Manage Windows Backup disk space screen click on View Backups under the Data file backup section.
A list of backups for different time periods will show up. You can delete older ones and just keep the most current backup. This will free up a lot of space if you have several backups periods stored.
You will get a message making sure you want to delete the backup. If you delete the most recent backup, there is an option to delete it and run the backup again so everything is current.
Now that we’ve been able to free up some space, let’s take a look at how to keep only the most recent system image stored. Go back to the Manage Windows Backup disk space window we were at previously and this time click on Change settings which is under the System image section.
Now select Keep only the latest system image and minimize space used by backup then click Ok.
Conclusion
Backing up your system is extremely important, especially if you have a lot of sensitive data and important files. If you allow Windows to manage space, it will automatically save backup periods but won’t take up more than 30% of space on the backup disk. When it gets to the 30% range it will start deleting older system images. Use these tips if you use Windows Backup and Restore and need more room on the backup disk. First create more space by manually deleting the older backups manually, then have it only save the most recent backups.
