Yang Zhang, is it your Internet connection that is slowing down, or the
host running bbackupd?

Some other options might be:
1. Setting the new MaxUploadRate setting to some value (in bytes per
second) around half your upload bandwidth, or lower if you want to
reduce CPU usage on the client;
2. Reducing MaximumDiffingTime to reduce the amount of time that bbackupd
spends performing heavy disk I/O;
3. Using a SyncAllowScript to prevent backups from starting during your
peak hours.
Cheers, Chris.
