Managing data
Data synchronization
Research In Motion (RIM) does not provide tools or applications for synchronizing data to remote data sources, so
you must build the synchronization logic into your application. See the
BlackBerry Java Development
Environment Fundamentals Guide
for more information about creating applications for sychronizing data on a
BlackBerry® device.
Types of data synchronization
Data synchronization
Backing up and restoring data
Synchronization type Description
Wireless (BlackBerry® Enterprise Server) The automatic wireless backup process on a BlackBerry Enterprise Server is designed to back up
data from the BlackBerry device to the BlackBerry Enterprise Server. By default, wireless backup
is active on the BlackBerry Enterprise Server. See the
BlackBerry Enterprise Server for Microsoft
Exchange Feature and Technical Overview
for more information about the BlackBerry Enterprise
Server.
When the automatic wireless backup process runs on the BlackBerry Enterprise Server, the
process saves application data with the user account settings and the other BlackBerry device
data that backs up.
Wireless (XML data) An application uses XML APIs to generate and parse XML-formatted data to send and receive over
a wireless connection.
Desktop-based (BlackBerry Desktop
Manager)
An application uses a USB connection to a computer to synchronize data with a desktop
application. This type of synchronization requires the use of the BlackBerry Desktop
Synchronization APIs, the BlackBerry Desktop Manager, and a desktop application that can read
data from the BlackBerry device using the BlackBerry Desktop Manager adapter. A BlackBerry
device user must manually start the synchronization process by running the BlackBerry Desktop
Manager, which notifies the application on the BlackBerry device to send the data to the desktop
application.
Desktop-based (USB protocols) An application uses a USB connection to a computer and native USB protocols to synchronize data
with a desktop application.
