I was looking to free up some disk space on our server. In the /var/cpanel/bandwidth directory I came across a bunch of .rrd files that haven't been updated since October 2015. Newly created domains don't have these files. There are also .sqlite files for every domain in this directory and they are current (within the last 24 hours). Anyone know if cpanel no longer uses the .rrd files and they can be safely removed?
