How to back up two internal hard drives using Time Machine? I upgraded my macbook pro and have now two internal SSD drives (I removed the old drive and also the DVD drive).

I have been using Time Machine to back up the 1st drive to an external drive, and I now wonder if there is any way I can also use Time Machine to back up the new second SSD drive.

Hope it makes sense..

so I back up my main SSD-1 drive to an external drive called Backup1.

and now would like to back up my second drive called SSD-2 to a second drive called Backup2.

Is it possible to use Time Machine for that?
No, you cannot do this with Time Machine unfortunately.

What you can actually do is backup both internal SSD drives to the same external drives - or backup both internal SSD drives to two different external drives.

However, you cannot setup it up so that SSD #1 only is backed up to external drive #1, and SSD #2 only to external drive #2.
