An update on the 'update' program
 .
Here's an update using Werner's dating method, even in the status lines.
I've included a listing of tarred files, mailed to root, also suitably dated.

I now backup ~124 Mb into 48 Mb of tgz on /mnt-system.
IceWeasel alone accounts for 91 Mb of the 124 Mb it might be noted.

Code:
#!/bin/bash
#
# new.backup: do 'chmod +x new.backup' & 'chown root:root new.backup'
#
cd /
STOR=update$(date +'%m%d%y').tar
echo -e 'Tarring data to '$STOR' in /tmp..\c'                                                     
tar -cf /tmp/$STOR KNOPPIX-DATA/home/  KNOPPIX-DATA/etc/ \
                   KNOPPIX-DATA/root/  mnt-system/boot/syslinux/syslinux.cfg
echo '..Done.'
cd /tmp
STORZ=$STOR.gz
echo 'Zipping to '$STORZ' in /tmp.'
tar -tf $STOR > ~/$STOR.lst
echo -e 'Patience; this may take a little time..\c'
gzip $STOR; echo '..Done.'
#
echo -e 'Moving '$STORZ' to /mnt-system..\c'
mv $STORZ /mnt-system; echo '..Done.'
#
echo 'All done.'
#
exit 0
