Back Up DB Error

[theodore]

Hi I try to back up my DB through Admin and the following error appeared:

"Fatal error: Allowed memory size of 20971520 bytes exhausted (tried to allocate 19143322 bytes) in /home/xxxxxxxx/public_html/admin/backup_management.php on line 158"

My site has over 10.000 articles and the size of the DB is about 100Mb.
Does any one knows how to increase thelimit?

Thnks

Theo

Increase the memory size allowed in php.ini file, or with ini_set() (http://www.php.net/ini_set), or even in htaccess.
