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?
