Some people have already replied to say to increase verbosity. For the
record, rsync takes the -v option to add verbose output, -vv is more verbose
and -vvv is more yet. Not sure if more than three v's changes anything.

For creating the initial snapshot I'd personally NOT recommend rsync. It
uses more resources than other systems if you just want to transfer a big
chunk of data. (it's meant to do more complex things)

As a matter of fact, I've not found anything that can transfer many files
faster than one large file. Therefore if you've got disk space to spare I'd
tar + bzip the initial sync, copy it with sftp and then use rsync on
subsequent copies.

Also, don't underestimate the bandwidth of fedex. You can ship a 1 TB drive
over night for $10. The latency is high but no DSL line is going to give you
that kind of throughput.
