I've got problem with hardware compression on my backup Exec setup. I've checked this thread but although that seems similar it doesn't strike me as being quite the same.
I know the files I'm backing up compress very well (tested this by compressing to .7z using 7-zip). However, when I tell my software to hardware compress, which my drive supports, I get 1.01:1 compression at best which is virtually useless given that my tests show it should work better. (admittedly hardware compression and 7zip will be using different algorithms).
Any advice appreciated.
Hardware: HP Ultrium 1760 width LTO4 tapes (800GB, 1.6TB compressed at 2:1)
Software: Symantec backup exec 11d
OS: Windows Server 2003
Files: images, "office" documents
