 Leif says, last week a question popped up when you talked about SSDs and backups. I have a related question regarding backup strategy. Can I now skip bootable backups and concentrate on backing up just user files only in this new world of our split volume APFS? And then regarding SSDs as a backup, shall I have one large SSD, say four terabytes, or separate smaller one terabyte ones to backup photos and maybe not any longer bootable Mac OS presently says I have several hard drives with different frequencies and also accounting for the risk of any one of them stopping working. So, yeah, you know, I have as as with many of us, I have been in the habit of bootable backups for, you know, let's say a decade, but it's probably many of them, because that's what you did. However, this new world certainly Apple is pushing us down a path where bootable backups are becoming more and more difficult to do. Do it, but it seems like Apple's priority is not on bootable backups anymore. And it's at least in part because our system our volumes are our boot disks are effectively split into two different volumes. There's the system volume, which contains the bootable part of the system, and then there's the user volume, which contains all the stuff that we do to the system. And only one of those, the latter one is writable. So there's very little chance that something could get corrupted on the system volume, especially because updates are done with snapshots, so you can always roll back. Of course, if the drive itself dies, then you don't have a way to boot your Mac, unless you have a bootable backup. So that there still is a relatively realistic use case for arguing to need one, but I'm not convinced that we're going to have the ability to make them for very long going into the future.
