The problem: Windows backup freezes at 97%
There are two built-in backup tools in Windows: Backup and Restore (Windows 7) and File History. The first tool is used to backup the entire system as well as everything else on your hard drive while the second tool backs up important folders in your user folder. Superb as they look like, users are frustrated by the error they encounter—Windows backup stuck at 12%, 57%, 97%. One user shared his experience in the forum:
“When I try to make a system image with the Windows 7 recovery backup tool, it gets to 97% and just sits there (I let it run overnight). I am using a USB external drive and checked it for errors. This happens on a Sony Vaio laptop and a Lenovo Ipad.”
How to resolve Windows 10/8/7 backup stalls at 97% easily
In short, there are three main factors that may cause this problem: some system files are locked by other programs, preventing Windows from accessing them; there is not enough disk space for backup; there are bad sectors in your system disk or target disk. As a result, Windows backup doesn’t go well as expected. If you find Windows backup is currently in progress but not completed even after a long time, you can try following methods to fix it:
Method 1: check disk errors
1. Tap the Search button on the taskbar and type “cmd” in the search box. Right click “cmd” and select “Run as administrator”.
2. Type chkdsk D: /f /r /x and press Enter. You can change the drive letter “D:” to others so as to check errors on other drives.
3. Type exit and press Enter to exit Command Prompt.
Method 2: disable the antivirus program or firewall temporarily
Sometimes, antivirus software or firewall can cause Windows 7/8/10 backup freezes. Try to disable them temporarily. Once the backup process is finished, enable them immediately because antivirus software is very important to ensure your computer’s security.
- Type firewall in the Windows search box and choose the option Windows Defender Firewall.
- Navigate to the left panel and click Allow an app or feature through Windows Defender Firewall option to disable the installed antivirus apps.
- Next, disable the installed antivirus program by unchecking the corresponding box.
- Then return to Windows Defender Firewall page and click Turn Windows Defender Firewall on or off on the left panel.
- Select Turn off Windows Defender Firewall (not recommended) at Private network settings and Public network settings. Then click OK to confirm.
Method 3: disable all the programs running at startup
- Tap the Search button on the taskbar and type “msconfig”. Select System Configuration from the search results.
- On the Startup tab of the System Configuration dialog box, click Open Task Manager.
- On the Startup tab in Task Manager, select each startup item and then click Disable. Close Task Manager.
- On the Startup tab of the System Configuration dialog box, click OK. Restart your computer to run the backup again.
- After Windows backup is completed successfully, you can enable all of your startup programs in System Configuration again.
