Not Export cache

Hello,

I have been maintaining our sites for several years and this is the first time this has happened to me.

I made a backup two weeks ago after cleaning up the /upload/ folder. I got to 450MB.
Two weeks later and without any modification of the site or addition, the backup of today is 700Mb.

While searching the .wpress with Tracktor, I noticed the cache folder and especially the page_enhanced folder which has the cache of my old domain names and even the localhost.

Is it possible to add a feature to ignore the cache?

If not, why such an increase in 2 weeks without anything being added?

Thanks
