When using ufsdump in Solaris to do backup is it compressing the files?


We upgraded our Sun Solaris server/OS from 7 to 9 and we are using the ufsdump to do backup.  ufsdump 0ufl $NOREW_DEV_NAME /dev/md/rdsk/$METADEVICE.   When we were in the old server, we only used one tape (40/80GB) DLT to cover a full backup of 79GB.  Now that we are on V9, somehow we use 3 tapes to cover a full backup of 76GB.  I'm wondering if the V9 is not compressing the files being backed up.  Is there an option in the ufsdump command to force it to compressed?

Did you do a  'touch /reconfigure'  after the update?

Can you please explain what is 'touch /reconfigure'.  I'm not a Unix/Sun Solaris expert.

Our problem was solved specifying:
/dev/rmt/0c and /dev/rmt/0cn (with c for compression)
