Time Machine: backing up 2 drives at once - Numo - 02-09-2021
Recently I made an external SSD my startup disk, so I am now using my iMac internal HD for storage. But I can't find out how to get TM to backup both of these disks at the same time.
I assume TM automatically backs up the boot disk. Is it possible to have TM include my internal drive when it backs up the external SSD?
I know I could back up the internal with CCC but that is an extra step and not automated.

Just pop into the options and check. Pretty sure it will backup everything, internal and external unless you tell it not to.
Ran my system that way for years, with 2 externals

Go into the "Options" in the Time Machine pref's and remove the second drive from the "Exclude" list.

That’s the rub - the only drive listed in the exclude list is the TM drive. The internal drive is also a boot drive, could that be the problem?

Weird.
Are both drives called "Macintosh HD" ...? There might be a conflict.
Maybe rename the external boot drive to "Macintosh SSD" and then let it back up once so that it updates the backup properly with the name-change and then reboot and see if the internal drive shows up in the exclude list.
(Just throwing stuff at the fan..)

Shouldnt be, TM really doesn't care.

It may already be backing up the internal drive, if you go to the time machine back up drive, and look in your back ups, it will tell you which drives it is backing up.

Sorry I wasn’t clear: what I meant was I want to back up 2 different drives in a single TM backup file. In other words, I’m trying to avoid making a separate TM backup for each drive.
