Jeff wants to know if Google Backup and Sync is a good way to back up his hard drive. Leo says he's used it and it works. It's not really designed to be a hard drive backup, but he can use it for something like Google Photos. But also remember that Google Drive isn't private. People can see user data online. So he wouldn't use it for sensitive data. Leo recommends iDrive because it does not only encrypt data, but it also has versioning, so it keeps versions of the data. It's a much better solution.
Spencer removed a hard drive from his RAID array and now he's having issues. Leo says some of the data needed from the reboot was on the missing hard drive. Can he just repartition the RAID? Leo says that the safest thing to do is copy off the data and then reinstall Windows. Then restore. That should copy the master boot record and get it all back to normal.
First of all, get a password manager such as Lastpass (TWiT sponsor), 1Password, or Apple's Keychain. Any password manager is better than no password manager. Secondly, it might be a good idea to create a backup (like your important computer files) of those strong passwords in case something goes wrong with accessing your vault of account information. Maybe make a USB key of passwords and store it in a super safe and secretive location at home just for worst-case scenarios regarding your master password.
If you recently bought a new Macbook to replace a much older Mac, you may have trouble restoring old backups of photos and video stored in iPhoto from the elder machine. Pictures in iPhoto are stored in a blob called the "library". You have to right-click on the icon (which is secretly a folder) and select Show Package Contents, then you can find the original photo files (possibly sorted by year) that can be copied to your backup location.
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.
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.
