Thanks for reporting this. I've never come across this issue so I'm guessing but I don't think this is a bug in TKLBAM, Duplicity or even in python-boto. It looks more like a networking problem. Something (e.g., a firewall on your Intranet) is disrupting your connection to Amazon S3. You can try running a sniffer (e.g., tcpdump/wireshark) to confirm or rule that out.

You may need to go through a proxy server to access Amazon. Ask your network administrator about that.

If that's the case you'll need to configure the software to route traffic through the local. You can do that by setting the http_proxy environment variable like this:

# e.g., http://10.0.0.168:8080/
export http_proxy=http://proxy.address.here:PORT/

tklbam-restore 1

Try that and report back so if anyone else runs into this we can solve it for them as well.

If it doesn't work, and you just want to migrate a machine you can always bypass Amazon S3 and backup to the local filesystem/NFS/FTP server using the "--address" option. See the documentation for details.

@Alon: we already have the retry patch discussed in the Launchpad bug report in tklbam-duplicity.
