When trying to perform a database backup (so I can update to the current version of concrete5) I get the following error after the page looks to be loading for 20-30 seconds:

Fatal error: Maximum execution time of 30 seconds exceeded in /home1/footepri/public_html/concrete/updates/concrete5.4.1/concrete/libraries/3rdparty/adodb/drivers/adodb-mysql.inc.php on line 641

I have successfully backed up my site before, but this time no luck. I don't even know where to start troubleshooting. Any ideas? Not a major issue - I just won't update concrete5 if I can't keep my files safe.
