It's now internet based life. So today everybody need to have a cloud storage for safety for files and photos. I used many cloud storage like dropbox, google one drive, now tumblr. Google one drive is one of them. It is easy to use because of it's a google product and it is connected to gmail. You can use via gmail account, that's why it is easy to use. If you need to keep safe of your documents , google one drive is the best apps for it. But not for video back up. It has storage limitation that is 15gb. If you need more storage then go for tumblr.
