Does anyone recommend turning off compression in order to speed up backups?

I have an external USB Travan tape drive, and the backup is so slow it's painful. The compression ratio (software) is 2% or less. I have a lot of music, video and exe and dll files on the system. Would turning off software compression speed things up significantly for me? Turning it on does not appear to help (2%???)

I doubt that you'd see "significant" speed increases, as only 2% of your data is compressible. The only way to know how much faster it will be is to actually run it without compression.
