Best backup practices and recovering lost data.
Backup and Recovery
Doug is a singing voice teacher who recently upgraded his Macbook Air with the new Apple M1 design. Leo says that Doug is the ideal candidate for the M1. But what Doug is experiencing is issues with his backups being restored. What Leo recommends is to use the old computer to upload all photos and videos to iCloud. Use the most recent version. The way the old iPhoto used to store them is in a big blob. Go to the Pictures folder and R/C on the library. Select "open contents." There he will see the original photos folder. Copy that over.
Charlie wants to know if he can make a bootable backup of his hard drive with macOS Big Sur using Carbon Copy Cloner. Leo says he can, but it's not all that easy. Apple has changed the way it does things ... again. It's more secure, sure. But only Apple can sign it. And that means he can't do it anymore without making a clone of the hard drive, installing macOS Big Sur to it, and let Apple sign it. BTW that's how ChromeOS works.
Rhonda is locked out of two different laptops running Windows 10 and Windows 8.1 respectively. She got back into Windows 10 after watching a few videos. Then she got locked back out after creating a new Outlook account. How can she get back in? There are a lot of legal documents and data she needs. Leo says that if she has a backup, then there are easier options. Rhonda says she did on the Windows 10 machine.
This is why it's so crucial to have backups.
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.
Mike's desktop has two drives in an IBM PC and when he went to defrag one, it disappeared from Windows 7. So he can't see it. What can he do? Leo says that try rebooting and see if he can see it on boot up. If not, try using a NewerTek Universal drive adapter to see if you can see it that way. If you can't, then the drive is dead. The good news is, drives are cheap. Leo recommends putting an SSD drive for your main drive and use the good hard drive for the backup. You'll get a huge boost in speed that way.
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.
Jessica's desktop is about eight years old and she has nearly a TB in free space on her hard drive. But she's concerned about the age of her computer. Leo says older computers aren't as slow as newer computers like the old days. So an older computer really isn't that big a deal. The more worrisome thing is the age of your hard drive. They can crash as they get older. So replacing the hard drive will be faster and give new life to your computer. Especially with a solid-state drive or SSD.
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?
