Backuppc is always going to be somewhat slower than native rsync because it is
using a perl version on the server side and working against compressed copies,
and on fulls it adds the --ignore-times option that forces the client to read
all the files to compare block checksums. I think there is also a difference
in
the way the transfer is reported, where backuppc shows the actual bytes
transferred which may be a small number compared to the data the client has to
read from its disk. The important metric is just whether you can complete in
the window of time you have.
