Encrypt your rsync backups without losing the efficiency...
One of the aims of encryption is to try to make any change to the unencrypted file completely modify how the encrypted file appears. This means that somebody who has access to a series of encrypted files gets little information about how the little changes you might make to the unencrypted file are affecting the encrypted file over time. The downside is that such security causes the encryption program to modify most of the encrypted file. If you then use rsync to copy such a file to the remote server, it will have to send almost the complete file to the remote server each time.
