You'd lose all the data, that is why using a compressed tarball on tape is a bad thing. Either compress files individually or maybe rely on the builtin hardwarecompression of the tapedrive, if you like.
How can you enable the hardware compression? I only have a logical device which I use with the -f flag of tar program.
Dependant on the tapedrive in question. It might be a dipswitch on the drive itself and / or it might be a command you can send the drive. I use SCSI DAT drives at all times and with these you can en- or disable hardware-compression with 'mt', like this: mt -f /dev/nst0 datcompression 2 (man mt, options can differ) For other types of drives you may need other means.
