This is a solid config! (and a very nice PC too!
)
One note though: Since most of the times it's not enough to simply backup individual files/folders (e.g. to an external HDD or an online cloud storage service like Google Drive), I recommend that you try free
system imaging software like
Macrium Reflect Free or
AOMEI Backupper Standard and use them to create at least one clean, full system backup image which allows you to restore your system to its exact state, as it was when you created that backup image.
The whole restore process takes only about 10-20 minutes to complete.
Other than that, you're good to go!
Thanks for sharing your config with us!
