HOW TO: Automated database backups (1 line of code + cPanel)

[judel]

Just so I know I'm doing this right, when I replace things like DBHOST with my host server, do I just add it after the -h or put it in quotes?

For example would:

/usr/bin/mysqldump -hDBHOST -uDBLOGIN

look like this:

/usr/bin/mysqldump -hlocalhost -ujudel

or

/usr/bin/mysqldump -h"localhost" -u"judel"

Also, is that /usr/bin/mysqldump universal or will it only work with Cpanel?

edit: and I think I'm missing something. When I did a test run, it seemed to find everything ok but gives me an error when saving the file. It says that permission denied when trying to save mybackup.sql.gz. Any idea why?
