I have a script that I run daily from my linux box to backup all files
on my Z.. It backs up my SD card but I dont have it backing up a CF card
(since I dont use one.. but it can easly be added..)

The backups it makes (of the /home partition at least) are identical to
the built in OS backups..
------------Backup script-----------------
#!/bin/sh

ZHOST=zaurus

# this is where the backups will be saved.
BACKUPDIR="/home/zaurus/backups"
BACKUPFILE=$BACKUPDIR/`date +%Y-%m-%d-%H-%M`.backup
LOG=$BACKUPDIR/`date +%Y-%m-%d-%H-%M`.backup.log
LASTLOG=`ls -tr $BACKUPDIR/*.log | tail -1`
KEEP=14

ssh -l root $ZHOST 'cd /;tar cf - --exclude home/tmp home usr/mnt.rom/card' > $BACKUPFILE
if [ -s $BACKUPFILE ]; then
   tar -tvf $BACKUPFILE > $LOG
#  diff $LASTLOG $LOG

   ## remove old backups
   COUNT=`ls -tr $BACKUPDIR/*.backup | wc -l`
   TOP=`echo $COUNT - $KEEP | bc`
   for FILE in `ls -tr $BACKUPDIR/*.backup | head -$TOP` ; do
     rm $FILE
   done

   COUNT=`ls -tr $BACKUPDIR/*.log | wc -l`
   TOP=`echo $COUNT - $KEEP | bc`
   for FILE in `ls -tr $BACKUPDIR/*.log | head -$TOP` ; do
     rm $FILE
   done
else
   # bad backup.. trash it
   rm $BACKUPFILE
fi
