Hi Les - thanks for trying it out!

It sounds like you are seeing about 300GB in 1200 minutes, or 4
minutes per GB.  That's about what I see on average when backing up a
real system initially.  Yesterday I backed up 33GB on a G5 Mac (the
Mac version isn't released yet), and it took 110 minutes.

However, incrementals are much faster: The incremental for the same
Mac took 7 minutes.  One of my Linux development systems (about 1.5GB)
takes 4 minutes to backup initially, but only 20 seconds to do an
incremental when just a few things change.  I backup my /home/jim user
directory, about 1.5GB, every 15 minutes and it usually takes 5-10
seconds.

You can restart the same backup and it will pick backup up where it
left off after a short delay.

Thanks again for checking it out!  Much appreciated.

Jim
