I'm a little perplexed. My scenario is that I have data loggers in

company keeps them hidden. In other words I can't have my backup
amazon ec2 server poll my data logger. Again, the need to push the
backup. I'm not really finding any information on how to accomplish
this.
Any suggestions would be greatly appreciated.
The way I do it is to establish an openVPN tunnel. Beware that
rdiff-backup is very sensitive to the link quality.
Agreed about the link quality, and so I would suggest that rather than
try to run rdiff-backup over a 3g connection, you run rsync, which is
much better at recovering from broken connections, especially with the
--partial and --link-dest switches (and, occasionally, --checksum). Each
machine in the field could rsync back to their dedicated folder on the
backup machine and then the backup machine can run rdiff-backup locally.
By combining the 2 programs in this way you can still get the benefit of
rdiff-backup's versioning '4D' backup.
I also recommend creating a snapshot on the source machine and backing
up from this rather than from the original data (which might change
while the backup is in progress). For this you want LVM (for Linux) or
VSS (for Windows) - I don't know what the equivalent is for Apples.
