Exclude cache and appdata_xxxxxxx from backups?

I am currently using Restic, which uses deduplication and incremental backups to do daily backups.

The problem is, my appdata_xxxxx previews folder and .optcache takes a long time to scan, because every single folder must be opened to check what is inside. While it is doable, it feels very inefficient as these folders are usually changed every day.

Are there any folders in data/ which I can exclude from my backups? Or is it recommended I include everything?
