Leo says that Fred is right to be concerned about the security of sending emails because the contents of the messages can be read along the way. If the email is going from one Gmail address to another, however, it would be secure. Ultimately, though, Leo doesn't recommend sending attachments at all. Opening attachments is how most people end up getting infected, and it doesn't just affect that person either. It will spread to all of that person's contacts, affecting their family, business, and the internet as a whole.
Philip keeps getting messages that his OneDrive is full on Windows 10. Leo says that OneDrive is built into Windows 10 and it syncs his data to it online. He can't really remove it, but he can disable it. This article at support.microsoft.com explains how to do that.
Bob needs a cloud based storage solution for being a digital pack rat. Leo says he should think about what he wants to store in the cloud and what he wants to store locally. If security is an issue, or if his data consists of large files like movies, then he should keep that locally.
The cheapest solution is Amazon's Glacier. This would be for things he doesn't need all the time. At $0.007 per gigabyte, it's ideal as a "just in case" scenario.
Keeping backups of photos taken with your smartphone is very important, in the event that your phone gets lost, stolen, or broken. It's also a good way to free up space on your device after you've taken a lot of pictures. There are a number of cloud photo backup options, including Apple's iCloud, Flickr, OneDrive, and Google Photos.
Josie wants to know how she can backup her iPad. Leo says that the easiest way is to back it up using iTunes on her home computer. She can also back it up to iCloud, but she'll only get 5GB free on iCloud, so she'd have to pay for more. The good news is that she can back it up anywhere, and iCloud Drive isn't that expensive. Another option is OneDrive. If she has a subscription to Microsoft Office, she can get unlimited storage to OneDrive. But that won't backup everything. Only Apple can do that.
Syncing files between multiple computers in different locations has been a difficult task. Syncing software will often end up creating duplicates of files because it can't determine which file should take precedence over the others. It also might not delete files in other locations if you delete them in one place, and therefore it isn't "true sync." This is why the concept of the "cloud" took over, and it has solved many of these file dilemmas.
