How to backup my Windows 7 system and data?

Q: How do I back up my Windows 7 system and data?
A: Windows7 comes with a more complete system backup function. We can choose the data that we need to back up, and back up your current system by moving the hard disk or system image. Of course, you can also restore your system from a backup file.
The specific backup operation is as follows: Open the control panel and enter the backup and restore center.

Select Set up backup.

Next, we can choose the location where you want to save the backup file. This can be an external storage device such as a mobile hard disk or a network location. After choosing to keep the location, we can continue to select the content of the data that needs to be maintained. Here you can specify the directory you want and then you can start the backup.
We can also use Windows7 to create a system recovery disk. When there is a problem with the system and cannot be accessed, we can use the Windows 7 installation CD to boot and select the corresponding system recovery disk to restore the system.
