Rory, When I am using tape compression I often...sorry.
When using SW tape compression amanda will know what the typical compression is for any given DLE and will (I believe) use the expected compressed size of the data when estimating overall tape usage. When I use HW compression I often lie about the tape length, extending the actually physical size by the expected compression amount so that I am able to utilize the full physical tape. This is very valuable for me in the couple of cases where I have a non-spanning DLE that is larger than the physical tape would be without compression, else amanda would report that the DLE was larger than the tape... What goal/outcome are you seeking ?
