It uses sophisticated byte-level algorithms to download only the changes instead of whole files or the whole database. Optimized for slow connections. The Polite Protocol will use only bandwidth left unused by other applications. Users can take advantage of idle time on the communication line so that when you aren't actively using your connection, F-Secure BackWeb goes to work in the background. Interruptible data transfers.
Users can download content over multiple sessions.
If the download is interrupted, F-Secure BackWeb saves what was downloaded and continues to download the rest of the file next time you connect. You don't have to look for the updates and manually download them.
