Suggestion.
Firstly, you have to do some housekeeping on your computer system.
Remove most HDD(s) out of your computer system, and use USB enclosure boxs.
This is avoid if something go wrong with your system, especially using multi- systems.
For Backup, go for Professional backup system.
Since you mentioned the importance of your system and program.
As for Free software, there are no proper Support should anything happened.
Even this &or others, forums users may not be able to do the proper job for you. (had to say this)
Finally, do you have any Professional Security and even a tiny malware can do much damages on not only your system partition, but also other HDD(s).
