Hardware Compression does not work

[Ayman Altounji]

When I backup to the Library, it stops after 40Gb, when I backup to a local DLT40/80 is backups more than 100Gb on 1 tape. When I look at the menu on the Library itself, I see that Compression is off voor both tapedrives inside. When I try to change the compression from automatic to 'on', it changes back to automatic. Is there an other way to turn on the hardware-compression?

Kind Regards,
