Common ways to backup system to USB drive
Backing up system to removable USB drive is a feasible way to prevent Windows failures. When serious problems arise, you can use the USB stick with system image to save the computer.
Compared with other devices, USB drive is cheaper and also more convenient as long as it has enough space for the system. To do this, there are 2 built-in Windows utilities, or you can also use 3rd party tool for better compatibility.
- Create a system image to USB drive:
In Backup and Restore which is available in Windows 11/10/8/7, there’s an option to create a system image.
You can follow the wizard to choose "On a hard disk", and select the connected USB as the destination.
The system image contains all required drives for Windows to run. It takes up more space and could restore your computer to an earlier date using System Image Recovery in the Windows recovery environment.
- Create a recovery USB:
In Windows 8 and above versions, you can search for Create a recovery drive and tick "Back up system files to the recovery drive", then select the USB flash drive as the recovery media.
A recovery USB like this allows you to re-install Windows from the drive in the WinRE. Meanwhile, it will remove all your files and apps.
Note: if you are running Windows 7, use the first method or try this way to create Windows 7 recovery USB.
- Create bootable drive with handy backup tool:
Whether you want to backup system to removable drive for data security, or create a bootable drive that can start your computer when it fails to boot properly, a professional backup tool like AOMEI Backupper Standard is a more solid and widely available option.
It supports Windows 11, 10, 8.1, 8, 7, XP, Vista, and allows you to create a bootable USB or CD/DVD with fewer errors.
Why can’t I backup system to USB drive and how to fix it
There are various problems and errors that might stop you from creating system image on USB, or creating recovery USB normally. I’ve listed some of them along with the possible causes and corresponding solutions, if you find them cumbersome, or can't solve your problem, please turn to an easier system backup method for a higher success rate.
Case 1 - USB can’t be recognized
Possible causes:
1. USB driver is physically damaged or not installed properly.
2. The drive letter assigned to USB drive has been already occupied by another drive in the computer.
3. USB drive is disabled in CMOS for the safety of computer in public place.
4. Manufacture of the newly installed USB device used unconventional flash memory chip and technology.
Coping solutions:
☛ 1. Check your USB drive carefully. If it fails on your computer, try it on another working PC to see if it can be recognized. If not, try another USB or another media like external hard drive.
☛ 2. You can reassign the drive letter if necessary.
☛ 3. Enter CMOS, find USB device from related setting items in motherboard, then change the state to enable.
☛ 4. Go to manufacturers’ official website to download the latest USB driver package or find the original CD driver.
Case 2 - Volume Shadow Copy Service error
Possible cause:
Volume Shadow Copy Service is the built-in technology of Windows allowing you to create backups of volumes. If you are prompted with related errors during backup, it probably because the service is stopped without noticing.
Coping solution:
Press Win + R key to open Run dialog box, enter services.msc and click OK. Find Volume Shadow Copy from the list and check its status.
If it’s disabled, double-click it to set the status type to Automatic, and click Start to enable it. You could learn detailed steps with screenshots in this troubleshoot post about Volume Shadow Copy Service Component error.
Case 3 - This drive is not formatted with NTFS
Possible cause:
This is a fairly clear indication. Windows Backup and Restore cannot backup system to FAT32 drive, so you should format the USB drive from FAT32 to NTFS at first.
Coping solution:
Connect the USB drive to your PC and right-click it in Windows Explorer to select Format. Then change the file system to NTFS and hit Start. Note the process WILL ERASE YOUR DATA, it's better to backup files on USB drive first.
Case 4 - The drive is not a valid backup location
It usually appears when you choose USB as the destination to create system image. This is because earlier USB drives didn’t have enough space and weren’t admitted as the storage location for Backup and Restore feature.
Possible causes:
1. The system version or USB driver is too old.
2. The USB has insufficient space.
3. The USB drive hasn’t been converted to NTFS.
Coping solutions:
☛ 1. Update your system and USB drive driver so that Backup and Restore can recognize the changed policy and allows backing up system to USB drive.
☛ 2. Use a larger USB with at least 64 GB space.
☛ 3. Remember to format it with NTFS (same approach as in Case 3).
*If none of above methods work, you can try another trick: creating a sub folder in the USB drive. Right-click it and choose Properties > Sharing > Share.
Select or add your own username, hit Share button. Then decide to turn on network discovery and file sharing for private network or all public network.
After sharing this folder, you can choose On a network location when creating system image, and entering your computer's login credentials accordingly. Thus you can also achieve the goal of backing up system to USB drive.
Case 5 - We can’t create the recovery drive
This error message might occur while creating recovery USB, and the causes are varied. Insufficient space, unformatted USB drive...most of them have been mentioned in above cases and can be fixed with the same solutions. For more details with screenshots, you can refer to this post: unable to create recovery drive.
