I have 5 external drives, But only 2 are on all the time. I have never counted how many photos I bring in a week, But usually on a normal week, especially if the weather is good, and I am out shooting 5 days that week, the number can be considerable. My back up drive is 3 TB. I use another external drive in which I bring in all my pics, and that is always on.It is 2 TB, and its contents change daily.That one is defiantly being backed up. My internal HD which is SST and holds all my apps is 512GB. My 3 other backup external HDs are only on when I have completed a folder on the active external HD that is always on, and I send that folder to all ?3 other drives, then turn them off.
There is no lock to click on the machine preferences, and the only drive to be excluded is the backup drive itself.
Yes, I would like ?to be able to make a notable clone drive

Despite googling how to add my Macintosh HD,?which is an sst [sic], I can find no way to add it to the time machine back up.
How can I back up my set [sic] Mac HD?
Jeannie?
How many external drives do you have??
Is it 1 with photos on it + 1 with Time Machine?
How many new photos do you bring in every week (# of images, or GB) (i.e., does the photos drive change a lot in any given period of time?)
I keep my recent/active photos on my main drive, which is continually backed up with Time Machine, and archive all my older photos on an external volume ¨C presently about 218 GB of old photos. Since that archive doesn¡¯t change very often, I don¡¯t use Time Machine to back it up, but periodically make an exact copy of that volume to a similar partition on a second external drive.
How many GB of your internal, boot, HD are in use?
How big is the Time Machine drive or partition?
Do you want to consider having a bootable clone backup?
By default, Time Machine should try to backup EVERY partition of EVERY drive in or connected to your computer.
It should have at LEAST 2 times the space as all the data being backed up occupies.
That said, it is possible to EXCLUDE particular volumes if you wish.
It if is indeed NOT backing up your main internal drive, (the SSD), the SSD must at some point have been added to this exclusion list.
Open System Preferences
Click on Time Machine
Click the lock and enter your password
Click on Options in the lower right
You should see listed any volumes excluded from backups
You can add or subtract volumes using the + and - signs
