Mark has been having issues where he can't do a time machine backup on his new M1 Mac. It gives him a "can't write a file" error. Does he have enough memory for it? Leo says it's not related to memory. It's likely a Time Machine issue. One of the reasons why Leo doesn't rely on Time Machine. Leo uses SuperDuper or ChronoSync to do a backup. RSync is native to the Mac, which ChronoSync harnesses. And SuperDuper is in beta on a bootable backup with the M1. So it's the way to go.
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.
Jim bought a new Mac and wants to know how he can set it up like his old one. Leo says he'll need a cable and connect the two. There is a tool in MacOS that will copy everything over and make it look just like the old Mac, only faster. Leo does recommend, though, to take an external hard drive and backup data just in case. Leo recommends either SuperDuper or ChronoSync. The old mac should also have someting called "target disc mode," which can be used as an external drive, dragging them over to the new mac. But Jim will probably need a thunderbolt-firewire adapter.
Bruce has a lot of data on a bunch of hard drives and he's looking for a way to catalog or collate the data, getting rid of duplicate files. Leo says there are de-duping tools that are designed to analyze and get rid of duplicates, but he'll run a risk of deleting something that only looks like a duplicate.
Lance upgraded to macOS Sierra and now his Time Machine isn't working. Apple Care hasn't been able to solve the problem either. He's even reinstalled the OS and Time Machine. It just hangs about 2/3 of the way through the backup. Leo says that nobody really likes Time Machine, especially when it doesn't work. No one really knows how it works, either. If Apple can't figure it out, it's a lost cause.
Daryl wants to know how long Carbonite will take to backup his hard drive. Leo says to take 740kbps x 60 then divide by 10. 10 KB per minute. If he does the math, it takes quite a bit of time. Carbonite knows this and as such, Daryl can request to have a hard drive sent to him and then he can back up his system and sent it back.
Dave is using Western Digital's backup software with his WD External drive. How can he be sure he's backing up all his data? Leo says that he can't since WD uses a protocol that backs up all files into one big master file (or what Leo calls a big ball of stuff).
