I have nothing. But, if you have a plugin here that works really well on older versions, it might be worthwhile to do what is necessary to get the plugin compatible with the most recent versions. It can't be that much coding. The server side storage is a good feature. Although, having an off-site (email to a gmail acct.) component to the backup solution provides a nice safe-guard.

I was interested in the DBC Backup until I noticed the version, compatibility and age of the last update of the plugin. # Last Updated: 2008-5-8
# Requires WordPress Version: 2.5 or higher
# Compatible up to: 2.5.1
Do you remain keen on this plugin and do you expect it to work well on future versions?
