However, the other suggestion to pipe straight through gzip (or other compression program) is better anyway.


Thank you!


Backup:

   1) shutdown: zero out unused space

         Figure out which partitions / and /boot are loated on.  Gparted
         works well for this..l Usually they are /dev/sdb3 and /dev/sdb4:

         partitions must not be mounted

         # zerofree -v  /dev/sd..
         # zerofree -v  /dev/sd..

   2) shutdown: make a dd and gzip

         Find the device name (/dev/sdx)

         Note: if the "dd" crashes on a USB3 port, try a USB2 port
               status=progress cuts your size in half.

# dd status=progress bs=4096 if=/dev/sdx | gzip -v > DeadStick.FC30.$(date +%Y-%m-%d)
