In case you were wondering where Lazybackup is, you are not alone. A good number of people are searching the web and the developer seems to have disappeared. The JED, as of January 2010, has no longer a link to the plug-in because the developers' website is down.
In the hope we will hear soon more about Lazybackup, we have posted the plug-in we use for our production sites till it is available in the JED. You can download the plug-in below and read more about this brilliant plugin here.
Update 1: The link has been restored in the JED - please download the plug-in through the JED (but we will keep a backup on this site for a while in case the link disappears again).
Update 2: LazyBackup 2 has disappeared again: "This extension has been unpublished for the following reason: * UR1-Broken Links."
Update 3: LazyDbBackup has been introduced on January 29, 2011 and is based on LazyBackup by Stefan Granholm. (GNU/GPL 2 or over license). This plugin was "internationalized" (for Joomla! 1.5 and 1.6) and modified to run with Joomla! 1.6 by Robert Gastaud.
Message from Stefan Granholm, on 09/15/2010:
Im very happy to hear its been updated for 1.6 :o)
And am very happy to see your work too, and I think it is a very good thing to Joomla, if not the best extension ;o)
This is what sharing is about, helping each other and make it free for all. Very good day to you.
Regards,
Stefan granholm
The LazyDbBackup Plugin is available in the JED. We have added the two latest versions to the repository below, just in case the plug-in is delisted again.
