'Bei Fen' is chinese for 'Backup', and that's what this plugin creates: backups!
You can create backups of your complete WordPress installation, only the files, or only your WordPress database.
Backups can be restored with 1 click (only backups created by version 1.3 can be restored)!
Both PHP4 (>=4.3.2) and PHP5 are supported now. Backups can be compressed as zip archives (PHP Version >= 5.2 only).
