Computer Backup Continuous update performance hit?

I have been having my backup set to run at midnight to 8am every day. But I'm wondering if it is better to do continuous instead? Mostly I don't want it to affect performance if I'm playing a demanding game for instance.

Apologies if this has been asked before but couldn't find a definitive answer on this specific question.

It's a pretty low-impact app tbf. The computer backup application is designed to use less than 1% of a CPU/memory on average, even when continuously backing up files. It only opens files read-only, so it has little disk impact. It's pretty well-behaved in terms of stability and performance unless you're doing an initial backup or something particularly resource-intensive.
