I am trying to make a virtual machine using VirtualBox. I have been following the comment David Anderson made for me here on this post (his comment I am talking about is at the bottom): Install macOS Sierra on VirtualBox?
I have gotten to his step #3 and finished it. I am now at step 4, but I haven't started step 4.
Before I finished this process I thought it might be a good idea to make a time machine backup of my drive in case I do anything wrong, also I haven't made a backup in about 150 days.
I'm just wondering if making a Time Machine backup with a sparse disk image containing a bootable installer will be a problem for the Time machine backup?
These are my computer specs in case they are needed for reference:
Macbook Pro mid-2014, Running macOS High Sierra 10.13.6 (natively)
