So, right now we're using DropBox to share various data files around between approximately 10 Mac OS X systems.
However, we already have an S3 account and everyone on the lowest DropBox plan of $10/mo seems too expensive.
So, I am contemplating something that would allow us to replace DropBox with our own home-grown solution. We are all fairly technical people and/or smart enough to follow some steps, so if it's not as "user friendly" as DropBox we're all comfortable with that.
There are plenty of docs out there that have bits and pieces of what I want but some of the tools don't seem to fit the requirements:
Transport security via SSL to the bucket
Encryption of bucket contents
Bi-directional syncing
Most of the scripts I can find on the internet use "duplicity" which appears to fail #1 (it doesn't look like duplicity supports SSL to S3 - the docs don't state but the protocol looks plain old http http://www.nongnu.org/duplicity/duplicity.1.html#sect6 )
Many scripts use gpg to encrypt files. This seems like it could work, however I have to make sure that each OSX client is able to use the same key to encrypt and decrypt files (key management is left to me to manage).
Finally, most of the scripts use one-way replication, e.g. using Amazon S3 as a simple backup store. As we'd be using Amazon S3 as the "repository" they fail this one.
Whew. So, I'd love a single tool that does this but after an exhaustive search I don't think one exists.
I'd be happy just knowing which tools out there can fulfill my 3 requirements, after that I can stitch together the rest. Any thoughts?
THANKS!
