i'm using Dropbox for Backup which means i keep all my files in my Dropbox folder (encrypted using encfs but that should not be relevant). I like this solution because it is automatic and keeps copies of my files on several machines at different locations. The only thing i could see go wrong is that Dropbox has some sort of bug that tells all my machines to delete the files. So currently i do a Backup of the Dropbox folder to an external Harddrive. With Amazon Glacier it seems affordable to automate Backup snapshots of my Dropbox. What i am looking for is a tool that will do this for me - the base case scenario would be that files would go from Dropbox (using their API) directly to Amazon as uploading the ~80GB from my home connection would take forever...

Thanks!
