It was awhile since the last update, and again both Pro and Lite editions are updated. 3.1 Pro got many more new tools and much improved database backup tools. Both versions feature many fixes and new user level settings for controlling plugin access for different user types.
Pro version Database tools are updated and expanded. Now, for each table you have optimize and repair options. Also, cleanup tools is split into two: one for optimization of database only, and other for repair. Sending email after backup is fixed, with few minor typos and errors displaying list of backups.
Most important new addition here is use of mysqldump program to create backups of the database. For this to work, plugin needs access to mysql program and also some PHP functions. New mySQL panel on Database panel is there to set and check all prerequisites. For manual and schedule backup jobs you can choose which backup method to use. If the mysqldump can’t be run, classic method will be used. Also, GZIP mysqldump method can’t be used on Windows servers.
Also, both versions are now fully compatible with latest build of WordPress 3.0.
After this, next step is to add sending backup archives via email and to add restore options for archived database files.
