okay, this is gonna be the last one then :-)

hdup in rdup:=20

Note:
  hdup uses the monthly/weekly/daily scheme, in rdup you only have full and
  incremental dumps.

Full dump:
  rm -f home-filelist
  ./rdup home-filelist /home | awk '{ print $4$5$6 }' | tar --create \
  --no-recursion --gzip --file `hostname`.`date +%Y-%m-%d`.null.tar.gz \
  --files-from -

  This generates (at my machine):
  elektron.2005-12-29.null.tar.gz

encryption:
  mcrypt -k 'secret' -a blowfish --mode stream \
  `hostname`.`date +%Y-%m-%d`.null.tar.gz

Note, that also in hdup this is a two step process, first the
tar is created, then it is encrypted.

Next it can be stored on a remote machine.

Incremental dumps look exactly the same and are actually better implemented
this way, because tar's incremental algorithm is taken out of the loop. That
"bug" in tar has given me headaches for a number of years now...
