How to back up clone while booting from it?
I back up my Mac using both Time Machine and a bootable clone - the idea being that if 'something goes wrong', I can boot from the clone and keep working. I read somewhere that once you start working from the clone, the clone itself will need to be backed up as changes are made.
My question is, how would I do this? Can I use TM? Assuming the TM drive is still connected, will it treat the clone like the original drive? Or will it continue trying to back up the original drive?
Either way, what is the best way to back up a clone of your primary disk while booting from the clone and using it to work?
Thanks for reading.
