Many folks tell me thay they would NEVER use Cloud Drives like Google, Microsoft OneDrive, iCloud, and such because “they're just not safe." Over the years I have realized that many folks have horrible online safety practices, like having easy to guess passwords that they often use across many websites. They also do not use Two Factor Authentication to further protect their accounts. And even now, many will use “Passcodes” that use biometrics like fingerprint or facial recognition to further validat the logins. No wonder they hear the stories from their peers about being hacked.
With strong password protection, using the Two Factor Authentication, or passcodes, there is almost no chance of ever having your cloud drive information hacked. #1: They would have to know your very strong password and #2: hackers would have to have physical control of your phone or device to have access to your cloud files. If you don't practice strong password practices, then you will likely be hacked at some point. If you are interested in seeing if your information has been hacked (usernames & passwords, emails, etc), go to the site Have I Been Pawned and enter the information to see how many times your email or password has been associated with corporate breachs and is out there in the dark web to be utilized. You will be amazed at what you may find out.
There are good basic security procedures to keep your web files safe. Learn more about them. Also realize that Cloud Drives like Amazon, Microsoft, Google, Apple are going to be the most secure of the many options that are out there. Also, YouTube will host your videos for free, and as long as you set the permissions correctly, no one will even know they are there unless you share a link to those movies with family. However, I would not use YouTube as a backup option. Keep backups of your video files in another cloud or at least several physical hard drives.
