DBC Backup 2 was a WordPress plugin to safely back-up your database. I stopped developing it in 2013 primarily due to changes in MySQL and WordPress … plus there were other free options which had serious developer teams looking after them.
DBC Backup 2 created its own file and exported this to the users desktop. The original idea was not my own - I took on an ‘orphaned’ plugin. So it was something of a passion project.
DBC Backup 2 was downloaded more than 14,000 times on WordPress.org
I wouldn’t use it now. If you are interested in SQL and learning more about it and WordPress - DBC Backup 2 archive is now online
