With SuperDuper Boot Clone is anything irrevesible in High Sierra If Need To Go Back to Sierra?
For Boot drive I'm using a 480GB PCIe SSD (OWC Mercury Accelsior E2)
My boot clone is a 1TB WD Black, partitioned into three individual boot-able drives. I use these three sections as rolling boot back-ups, cloning via SuperDuper every 3-4 days.
This way, I can revert back to 3 days ago, 7 days ago, 10 days ago etc... If I ever discover something going sideways with my system. It's an insurance plan for drive failure, and insurance plan for an update causing instability.
Question: Given this back up plan, If I install High Sierra, is there anything irreversible here? Normally don't sweat testing out system updates, but the new APFS thing has me thinking out loud on this.
