Can I use a flash drive to backup my computer?

 

Hi, everybody. I have a Lenovo desktop running Windows 10 Home version. I just want to create system image Windows 10 on my 4 GB USB flash drive but it fails. What went wrong? How do I backup computer to USB flash drive? What is the best flash drive for backing up computer? Thanks.

Backup Computer to USB Flash Drive

USB flash drive is very portable, so many users want to backup computer to USB flash drive and you can definitely do this. Afterward, you don't need to worry about system failure, program and data loss (you can easily recover files from a crashed computer) due to reinstallation. And this process is tedious and time-consuming. 

But sometimes the system backup failed, probably because there is not enough space to hold everything on the system partition. Then, what size flash drive do I need to backup my computer? Indeed, the actual size of a fresh Windows 10 is around 15 GB. That's to say, if you want to create Windows 10 system image backup, you need a bigger flash drive(at least 16 GB)

Besides, considering data security and transfer speed, you need to use a reliable USB 3.0 flash drive for backup. All of the branded USB drives are affordable and have different sizes, such as, SanDisk Extreme PRO, Sandisk Extreme Go, Kingston DataTraveler SE9 G2, Samsung Bar Plus, Kingston Data Travel Vault, PNY Pro Elite Series etc.

What should I backup on my computer? 

In a computer, there are two important things - system and personal data, thus you need to create system image and file backup. Here are some of the reasons why I say this: 

Ensure secure boot and data security: If you create a system image, you can return your computer back to normal in a short time while the system crashes. And you can restore all of your files. If not, your computer will fail to boot and everything on it will disappear, including OS, personal files, installed apps, system settings, etc. 

Avoid accidental data loss: Creating a system image backup only includes files on the system partition and no files on the other partitions. Thus, if you don't want to lose any data, it's suggested to create a file backup. They deserve to be backed up separately. There is no doubt that all personal data are unique and cannot be downloaded from anywhere.

To backup system with the built-in tool, Backup and Restore (Windows 7), you need to create a sub-folder in the USB drive at first.

Step 1.  In Windows 10, type Backup in the search box and select Backup settings from the result list. Then, you will see the following interface, scroll down to Looking for an older backup and click Go to Backup and Restore (Windows 7).
