well... I have one server with all our project data on, the backup job is roughly about 7.5TB. At the moment the job runs at about 800MB/min (very slow), and ohh yes, this is to tape. i am using a MSL6000 series library with 2 LTO drives in it. we have just baught a MSL8050 library, with 2 LTO4 drives in. This is just one backup job, does not include our other servers data, our SQL environment and our Exchange Environment. So if I can increase my backup time with hardware compression, which is why I asked the question, that will be great!!! if we talk about a 30% decrease in time, it might as well be 30hours. :)

Sorry, the MSL6000 LTO drives are LTO3

On tape drives I always use the hardware compression. I haven't noticed a big change in the backup times since it is hardware compression just make sure that you use the hardware compression and not the software compression if your backup software. I think that most software has hardware compression turned on by default so unless you have turned it off then you are probably running compressed now.
