and the directive is "Unix Standard Directives". During backup my DLT will
get full at 15Gb, I wan't to enable compression on my DLT Drive. My
question is, how to enable the compression? Should I change the directives
into "Unix with compression directive" then compression will be enabled? or
should I configure my Autoloader to use /dev/rmt/2cbn instead of 2hbn, (I
understand "c" in 2cbn means "compressed")? Everyone's help is highly
appreciated.
Basically you aer correct, "Unix with compression" will compress on the
client and it is recommended not to use hardware compression on the drive
when using this directive.
The behaviour of the different /dev/rmt entries is dependant on the inbuilt
drivers or the st.conf entries however it is usual for "c" and "u" to be
hardware compression on the tape drive.
