Just ran it manually, when using gzip i get this after it cas compressed 31 tables:
Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 21605379 bytes) in /home/thecodec/public_html/forumz/includes/mysqlbackup.php on line 498

So using GZIP is causing me to run out of memory?

EDIT: in fact i just turned off GZIP and get the same thing, it always ends on
