I see a lot of people are satisfied with their backup solutions, which is great. The thing about your data or anyone's data is
- data isn't data until it's backed up, just temporary files
- backups aren't backups until recovery is tested
With regard to the second point, like many people, I use Time Machine, and the one time I have needed to recover from a Time Machine backup, I discovered there were folders and files inexplicably missing. Consequently, I don't trust it as much as some people. I still use it, but I have a second line of defence in that most important data goes to DropBox as well as Time Machine.
The point is that if any failure means a new logic board and new SSD, there are going to be a lot more people attempting to recover from Time Machine backups afterwards than previously when the disk didn't need to be replaced. I am expecting we will hear about others with missing files afterwards, because like any software, it's not perfect. And certainly not as perfect as some people are staking their data on.
