One of these days I'll get around to updating the script :) By: Travis http://colinmccann.com/code/automated-off-site-mysql-backups-with-cron-and-php/comment-page-1#comment-13242 Travis Thu, 30 Jun 2011 03:15:27 +0000 http://colinmccann.com/?p=19#comment-13242 What about the need to turn the site off before the backup taken? Or lock the tables then unlock them when the dump is done? mysql> FLUSH TABLES WITH READ LOCK; mysql> UNLOCK TABLES; I'm new to this so be easy on me.

How about: <pre class="jush-php">// 7 days * 24 hours * 60 minutes * 60 seconds = $one_week = 604800; </pre> ]]> By: admin http://colinmccann.com/code/automated-off-site-mysql-backups-with-cron-and-php/comment-page-1#comment-3650 admin Sat, 13 Mar 2010 19:47:55 +0000 http://colinmccann.com/?p=19#comment-3650 That would certainly work. However, it's been my experience that a little bit of processing power (in this case, very little) is a good tradeoff for extended readability. This thing only runs once a day :) By: John http://colinmccann.com/code/automated-off-site-mysql-backups-with-cron-and-php/comment-page-1#comment-3634 John Fri, 12 Mar 2010 23:11:50 +0000 http://colinmccann.com/?p=19#comment-3634 I know its a pedantic optimization, but shouldn't <pre class="jush-php">$one_week = 60 * 60 * 24 * 7; </pre> be <pre class="jush-php">$one_week = 604800; </pre> ? be ?]]>
