Bill has thousands of images on CDs. Is that the safest way to keep them? Leo says Bill wants to get them all in the cloud ASAP. Burned CDs can oxidize and stop working over time. Sometimes within a year. So he wants to have other options, including putting them online.
Wayne notices that Time Machine is taking a ton of space on his external hard drive. How can he minimize that? Time Machine says it's full. Leo says that he can adjust the amount of space Time Machine uses, but it can get a bit finicky when he messes with what Time Machine thinks it needs. Go into the System Preferences pane and there he can go into options and delete or disable the local backups on the main hard drive. That'll clear out some space. Time Machine should do that. It also keeps a local backup image and should delete the older ones as it does.
Ed wants to be able to take a snapshot of his Mac hard drive and use it as a backup, but still have a backup on the same drive. Will SuperDuper do that? Leo says it's called an Image, or Ghost. Some may be able to do that, but SuperDuper isn't one because it takes up the entire drive so he can use the image as a bootable drive. Leo recommends Carbon Copy Cloner or ChronoSync. Both will match folders, but not the entire drive. He can also image the hard drive using macOS disk utility onto a backup drive.
Matt wants to know about doing incremental backups on his backup hard drives. He wants to be able to sync his current hard drive to the backup automatically. Leo says that Windows Backup will do that. And you can do it by plugging in the drive, running the backup, and then unplugging it for storage.
Just in case something goes wrong, make sure to back up your Mac Computer before committing to an OS update as Apple releases Big Sur in the near future.
1. Move your data to a new drive
2. Create a ghost user account in the internal hard drive
3. Create a copy of the home directory on the external drive.

Dave lives in a town that was recently effective by the wildfires and he discovered that everything from his internet access to his phone service was disabled. Leo says that's because Dave's location uses fiber optic cable and as such, when firefighters cut the cable while fighting the fire, it disabled EVERYTHING.
Stan wants to know if he should wait until Big Sur or upgrade to macOS Catalina now? Leo says that you have to upgrade to Catalina first, since it eliminates all 32 bit apps. This will give you time to convert your other 32 bit apps to 64. It'll be pretty straight forward. But moving up to Big Sur may be more problematic because of how they approach kernel use. But you could wait and see what happens and stick with Mojave until Big Sur comes out and then see if you have to. Why do it twice if you don't really have to?
If you still insist on using your Windows 7 computer and are scared of using it thanks to Microsoft's lack of continued support, it is still okay to use it offline. If you don't take it on the internet, you significantly lower your risks to catch anything harmful for the PC. Plus, most of your permanent applications will still work as long as there is electricity to power the computer! However, you should still be sure to back up important files onto an external hard drive, as staying offline means no access to cloud backup services.
Rene doesn't have a computer or WiFi. She relies on her mobile phone for her internet. Her phone is four years old and she is looking at the Samsung Galaxy S10E. Leo says that it's a year old, but there's nothing wrong with it. The latest model is the Galaxy 20, but there's no "E" model. Will it be difficult to transfer data? Leo says no. There is an app that will copy data from one phone to another, and it's really easy. She'll just have to be sure her Samsung Account is logged in and the backup is turned on. It'll be in the backup and reset settings.
Gloria wants a recommendation for a reliable 2TB hard drive for her computer and a web camera for zoom. She's taking a class. Leo says that Seagate makes a really good one, but hard drives are pretty ubiquitous now, and the price is dropping. So you can get two of them and swap them out when you backup your data. Swap them out every other week. Also, rely on a cloud-based backup like iDrive (a sponsor of the radio show.) Ideally, you want 3 copies, 2 kinds of backup formats, one off-site or in the cloud.
