Windows 7 backup freezes

Hi Royce128,

Thank you for visiting Windows 7 community.

This issue occurs if some components cannot be copied. I suggest that you temporary disable the anti-virus and firewall. If you still face the same problem, then open the folder C:\Windows\Logs\WindowsBackup.  When you start backup, a log file "Backup Files*_error.log" will be generated. Please open the file when backup hangs.

If there is no valuable information in the log, please open the folder C:\Windows\Logs\CBS, copy the file CBS.log and paste to Desktop. Then open the file CBS.log on Desktop, check the last part of this log to try to find which file cannot be backed up during backup process.

If the issue persists even after disabling firewall and anti-virus then let’s disable all startup items and third party services when booting. This method will help us determine if this issue is caused by a loading program or service. Please perform the following steps:

Step 1: Perform a clean boot

Note If the computer is connected to a network, network policy settings may prevent you from following these steps. We strongly recommend that you do not use the System Configuration utility to modify the advanced boot options on the computer unless a Microsoft support engineer directs you to do this. Doing this may make the computer unusable.

1. Log on to the computer by using an account that has administrator rights.

2. Click StartCollapse this imageExpand this , type msconfig.exe in the Start Search box, and then press ENTER to start the System Configuration Utility. Collapse this imageExpand this imageIf you are prompted for an administrator password or for confirmation, type your password, or click Continue.

3. On the General tab, click Selective Startup, and then click to clear the Load startup items check box. (The Use Original Boot.ini check box is unavailable.) 

4. On the Services tab, click to select the Hide all Microsoft services check box, and then click “Disable all”.

Note: Following this step lets Microsoft services continue to run. These services include Networking, Plug and Play, Event Logging, Error Reporting, and other services. If you disable these services, you may permanently delete all restore points. Do not do this if you want to use the System Restore utility together with existing restore points.

Click OK, and then click Restart.

After doing these steps, follow the second step from the KB article mentioned below:
