Frank, Since you are using the Magstar tape subsystem, I would recommend using hardware compression for your Exchange data. I know that you generally use client compression, but you can use both in the same library.
It is my understanding that performing client compression on Exchange will slow backups down considerably. -- Joshua S.

When using TSM to back up our Exchange servers I was told by our Mail team that Microsoft said that client "compression" was to be turned off. Does anyone know if this is true.
