The problem:
Amazon S3 storage protocol is "all or nothing" meaning that you can not modify a file on Amazon S3 and you have to upload (S3 PUT) the whole file again. This implies that backup and synchronization to S3 are inefficient. Any file modification forces you to upload the whole new file again, not just what was changed. So you are wasting unnecessary bandwidth and the backup process is significantly slower!

The solution:
S3rsync resolves this limitation and allows you to use Rsync bandwidth efficient algorithm that enables to upload only partial files that were changed. This is done by connecting to our Rsync servers located inside Amazon facility (Amazon Ec2). Using this functionality enables you to fully benefit from Rsync power.

Now you can save Amazon bandwidth cost and reduce your backup time!

Example: A daily backup of one giga Outlook PST file When using common S3 backup and synchronizations utilities the whole one giga is uploaded every day. When using our S3rsync service only few parts of the pst file, that were actually changed during last day, will be uploaded compressed.
