The original message in the thread showed that the OP is using --volsize 
5, meaning he's having trouble reliably uploading 5MB volumes.  Looking 
through his message headers, it appears his internet access (at least 
for the post to the groups) starts at wtl.worldcall.net.pk.  .pk is 
Pakistan.

I don't think "direct to S3" backups are appropriate for a connection 
that unreliable.  I have a much more reliable connection, but the uplink 
is slow, so I use duplicity to back up to a local disk.  I then have a 
separate cron job to sync the local backup to S3.  That way the backup 
completes quickly, and the sync to S3 can poke along (or for the OP, 
retry many times) without holding anything up or failing the backup.

The only downside is that you need to have enough local disk space to 
hold the backups, at least until they're uploaded.
