Where ever you store data, it is always a good idea to always have a backup of your data, as you never know when disaster strikes. The two common ways to backup are either using a portable hard drive or a cloud service such as OneDrive, google drive or another provider.
Cloud Services – With cloud services, you can get a free version which provides you with a small amount of space to start with, after that there are different price plans.
Portable Hard Drives – You can buy a range of different-sized hard drives that can be with you at all times ensuring that you always have a copy on you.
