Technically, you can back up your PC to a flash drive, including a USB drive. A flash drive is the first choice to save your data because it is relatively small, easy to carry, and works well with most computers.

As for what size flash drive you need to back up your computer, normally, Windows recommends 16GB size of the drive is enough.

However, it is widely accepted that using at least a 32GB flash drive to back up a Windows system is better. It depends on how many applications and other stuff are on your computer. For example, if you plan to back up 20GB of data, you should have a flash drive larger than 20GB, leaving a little extra space because some free space is always useful. Besides, for a small Windows 10 system, a 16G flash drive is enough. There are a variety of sizes of flash drives, such as 8 GB, 16GB, 32GB, and 128GB, and you can choose the size of a flash drive according to your actual needs.
