Simple, semi-anonymous backups with S3 and curl

Backing stuff up is a bit of a hassle, to set up and to maintain. While full-blown backup suites such as duplicity or CrashPlan will do all kinds of clever things for you (and I'd recommend either for more complex setups), sometimes you just want to put that daily database dump somewhere off-site and be done with it. This is what I've done, with an Amazon S3 bucket and curl. Hold onto your hats, there's some Bucket Policy acrobatics ahead.

There's also a tl;dr at the very end if you just want the delicious copy-pasta.

Bucket setup

amiorin

    import com.amazonaws.services.s3._, model._
    import com.amazonaws.auth.BasicAWSCredentials

    val request = new ListObjectsRequest()
    request.setBucketName(bucket)
    request.setPrefix(prefix)
    request.setMaxKeys(pageLength)
    def s3 = new AmazonS3Client(new BasicAWSCredentials(key, secret))

    val objs = s3.listObjects(request) // Note that this method returns truncated data if longer than the "pageLength" above. You might need to deal with that.
