Backing up to S3 securely and efficiently, is. Two things should be addressed in the intro to that howto: 1. Does using rsync in this fashion take full advantage of rsync? In other words, does s3fs permit rsync to obtain a hash of a portion of a file, and update a portion of a file, or do those operations require the transfer of an entire file. 2. While S3 may encrypt things on their end, some users would prefer a solution where encryption happens locally, so the data is safe over the wire, as well as when in storage. Where, if anywhere, does s3fs encrypt the data? Probably digging into the s3fs documentation would uncover the answers to these questions. One of the comment to the article mentioned you needed to use the commercial version of s3fs to get encryption: http://www.subcloud.com/ -Tom -- Tom Metro Venture Logic, Newton, MA, USA "Enterprise solutions through open source."
