Question <ip>.tar.gz files found causing problems

[BizMarquee]

This morning I found 2 large files in my folders

/usr/local/psa/admin/htdocs/

and

/usr/local/psa/admin/htdocs/..

one file was named <IP>-quota.tar.gz and the other was <IP>.tar.gz

what are these files and what creates them?

It does not look like a result of Plesk operation.
I would suggest you check what is the content of these archives first. Then check bash history - maybe it is results of manually running some kind of CLI utilities.
