Although I find the Revisions option helpful in the post editor, I certainly don’t need the last 50 versions of any given post. That can quickly bloat any database. Backing up your website can be tough with a huge database. Try using these snippets to either disable post revisions or limit them to five. (Note, change the number 5 to whatever number you want.) Choose one or the other and then add it to your wp-config.php file in the root directory.
// disable post revisions
define('WP_POST_REVISIONS', false);
// limit five post revisions
define('WP_POST_REVISIONS', 5);

I personally hate when revisions are disabled. I write for one or two blogs that have completely disabled them and it is very frustrating. Firstly, because from time to time I will lose a connection and lose all my work. And secondly, because I am unable to refer back to previous drafts. I believe a few drafts are best and you can then periodically delete old drafts that are not necessary.

Great point. How do you delete old drafts that are not necessary? I didn’t know that was an option.
