I'm trying to make a backup prior to doing the first update in a year on my site. When I attempt to run a backup from within the Dashboard, I either get a completely blank web page or one with this message:

"Fatal error: Maximum execution time of 30 seconds exceeded in /home/jcarls_ds/ffez.com/site/updates/concrete5.6.1.2_updater/concrete/libraries/3rdparty/adodb/drivers/adodb-mysql.inc.php on line 644"

My environment information is shown below. Any idea what is happening? I'm trying to upgrade because the current version won't let me edit default page layouts. It shows the layout, then immediately moves to the first page on the site and I wind up editing that instead. Thanks for any help...
