eamon – I am not the creator of this plug-in but I am going to assume that leaving this plug-in as admin only is a good idea for security reasons. However, if you wanted to change it personally on your own you could edit the PHP file directly.
The file you would want is backup_and_move.php. These two lines:
add_menu_page( 'Backup and Move' , 'Backup Move' , 'import' , 'backup_and_move-plugin' , 'backup_and_move_option', home_url().'/wp-content/plugins/backup-and-move/img/backup_and_move.png', 40 );
add_submenu_page( 'backup_and_move-plugin' , 'Manage backups' , 'Manage backups' , 'import', 'backup_and_move_previous', 'backup_and_move_page');
Add the two admin menu pages. The two WP functions for these hooks is here:
http://codex.wordpress.org/Function_Reference/add_menu_page
http://codex.wordpress.org/Function_Reference/add_submenu_page
Just change the permission level for both functions and re-upload the .php file. Right now it looks like both pages require access to the “import” capability, which usually only Admins have.
For more details and capabilities look here: http://codex.wordpress.org/Roles_and_Capabilities
I would recommend reading and understanding the type of change you’re making, however if you just want to make the change quickly switch “import” to “publish_posts” on both lines. This should give users at the author level access to this plug-in.
