MacOS

How many computers do you have at hand. Years ago I used to have two computers. A Mac Book Air and a Mac Book Pro. Eventually I sold the Mac Book Air and just used the Pro. I went to an event with the Pro and it was stolen so for a few days I was without any computer.

I then bought a much cheaper Mac Book Pro and since then my collection of computers has grown. My work horse from 2016 onwards was a Mac Book Pro, but during the pandemic I got an HP machine running windows. Now it’s running Ubuntu. I also have a chrome book as a spare.

Recently I was using a one terabyte drive to backup a half terabyte drive and it would take four and a half hours to backup and I think I may have figured out why the software was taking so long. It’s because it was never designed to be used as I am using it.

Time Machine is designed to work with a hard drive that is smaller or as big as the system it’s backing up. When you get a one terabyte disk to backup a half terabyte hard drive it has the opportunity to save many more files than are on the system and this is fine initially but over time the number of files that it has to check gets larger and larger until finally it takes hours, rather than minutes to backup.
