Can I Make a Snapshot of My Hard Drive & Back It Up Simultaneously?

ChronoSync

Episode 1743

Ed from Ontario, California

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. 

How can I Prevent Duplicate Files While Backing Up?

SuperDuper

Episode 1576

Jim from Maryland

Jim found a duplicate file on a backup hard drive and wants to know how he can find other duplicates. Is there an app for that? Leo says that a program that can prevent duplications when backing up is SuperDuper by Shirt Pocket Software. Jim can set it up to mirror his internal drive and then if the internal drive dies, he can boot up from the external drive. Gemini Duplicate File Finder will do the job for the Mac, and it's $20 to buy. But be sure they're looking inside the file to verify it's a duplicate!

Can I use Time Machine with macOS Mojave?

SuperDuper!

Episode 1546

Charles from Virginia Beach, VA

Charles wants to know the best way to set up Time Machine on his Mac with macOS Mojave. Leo says that in the new OS, there is a new APFS file system, and there have been backup issues with Time Machine and others. He may need to use an external drive formatted with the old HFS file system. That will insure that if his internal drive dies, his backup is secure. Leo also recommends not using Time Machine as his primary backup system. He should make an image backup with SuperDuper.

Is my SSD drive failing?

Episode 1519

Mike from Dana Point, CA

Mike upgraded his computer with an SSD hard drive and after two years, he's getting a drive failure error. SuperDuper said that his hard drive was failing, and won't run. But Crucial, the drive manufacturer says that it isn't and could charge him $500 should they look at it and there's nothing wrong. Leo says it could be a false positive on the part of Super Duper. SuperDuper's SMART technology feature is designed to predict when your drive is going to fail. Problem is, it's not all that smart.

Is WhatsApp secure?

WhatsApp

Episode 1516

Patrick from Palo Alto, CA

Patrick uses WhatsApp, but he's concerned about security on his phone. Leo says that the danger isn't that the app will be malicious. It's a safe app if he gets it from the Google Play or iOS App stores. But it is owned by Facebook, and they will use his data for advertising. It isn't using personal details, but some details such as search data, likes, and keywords.

Patrick is also worried that his old iPad isn't being updated anymore. Leo says that while he won't get the most recent iOS, the security updates will continue. Nothing to worry about there.

Should I reformat my hard drive to speed it up?

Apple iMacs

Episode 1493

Dana from Rancho Santa Margarita, CA

Dana wants to know if he should reformat his iMac hard drive to make it run faster. Leo says often that's the best thing to do. Since Dave has a bootable image from Super Duper, he can do it and be back up in minutes. He should just boot from the image, then copy the image to his hard drive and he'll be back up. Sometimes it just takes a little spring cleaning. Better yet — he can get an SSD and use the hard drive as his data drive. His computer will be a lot faster with that.

SuperDuper

Episode 1429

Eric from Bridgewater, MA

Eric converted to High Sierra on his Mac and chose APFS on Time Machine. Now he's got trouble. Leo says that Apple cautioned not to do that. Can he at least downgrade? Leo says that the good news is there was no data lost, so he could format it to downgrade from APFS and then let it backup again. Eric should check out this article at macobserver on how to use Time Machine with APFS. He shouldn't convert to APFS if he has a Fusion drive just yet.

What is a good alternative to Apple Time Machine?

SuperDuper

Episode 1417

Chris from Miami, FL

Chris says that his Time Machine won't let him set when the backup happens. It just does it when it wants to. Are there any alternatives? Leo says that SuperDuper is a better option. It can not only back up his internal drive, but it can make his external drive bootable so that if his hard drive dies, he'll be back up and running within minutes or even seconds!
