I personally use SuperDuper for keeping a local cloned copy of my boot drive (this means I can quickly get up and running should anything bad happen there). To add to what the others have said, keep a good backup system for when/if you have to do any troubleshooting. I agree with the others too, there's little routine maintenance that's worth doing - indeed anything you do is likely to cause trouble that you didn't have. I have a 2011 MBP with an ssd running El Capitan, I'm wondering if there is any routine maintenance I should be doing? As well as Time Machine backups, of course. Maybe I am a bit paranoid but I did lose almost all of my photos, (slides), from my time in the Air Force when I was a fuzzy faced young lad a long time ago. Bit of a pain but I have a lot of photos I would not like to lose. I only connect my CCC backup disk for the time it takes to do an incremental backup and then the drive goes to a place removed from the house. While the risk of a ransomware attack may be small for Mac OS so far, my friend on a PC was compromised and decided to tell them to get lost but recovering from that was a lengthy PITA.

My thinking for the CCC backup is that if I have a problem with the built in HD I can boot from the CCC back up and be up and running in the time it takes to do that. Well probably you are well enough backed up that way. Both are good I just now take a couple of my umpteen (Time Machine) backups to a safe deposit box to switch out with the drives there when I add some important things. I stopped using Carbon Copy, and will probably stop using Carbonite when my subscription expires.
