Yosemite Server Backup, version 8.1 and above

Most tape storage devices advertise a 2:1 or greater compression ratio. This is based on tests done under optimal circumstances for compression. Most data within a real world environment has built in compression added into the file type. Common file types such as JPG, and MS Office Files that end in x, are encoded in a compressed format. Other types of data can compress very well. You will commonly see higher compression rates on Database Log files (ldf, log, etc) and text files.

Additional Notes:
Compression is completely dependent on the type of data being backed up. If you are backing up a dataset that is primarily in a compressed format (jpg, zip, docx, xlsx, mp3, mpg, etc), you will most likely receive less than a 2:1 ratio.
