    Further refinements to the personal backup idea.
    .
    I've incorporated all of Werner's excellent suggestions, and since
    I found I never referred to the tar listing, that's been omitted.

    In examining the remaining contributors to the 'personal backup', I found
    that not only is .mozilla the real space hog, but its caches are its
    biggest contributors. It is possible to clear at least one of these caches
    with a quick trip to the IceWeasel Edit>Preferences GUI before making
    a backup, resulting in a great reduction in the size of the stored file.

    A revised listing is as follows:
    Code:
    #!/bin/bash
    #
    # new.backup2: do 'chmod +x new.backup2' & 'chown root:root new.backup2'
    # Before backup, Go to Edit>Prefs on IceWeasel & 'Clear Now' the Off-Line cache.
    #
    cd /; STOR=/mnt-system/update$(date +'%m%d%H').tar.gz
    echo -e 'Compressing data; patience, this may take a little time..\c'
    tar -czf $STOR KNOPPIX-DATA/home/  KNOPPIX-DATA/etc/ \
                   KNOPPIX-DATA/root/  mnt-system/boot/syslinux/syslinux.cfg 
    echo '.Done.'; echo 'Restore using the command, tar -xzf '$STOR' -C /'
    #
    exit 0
    Now if some clever person here will inform me of some appropriate API,
    assuming there is one, we might automate that effort as well. This is
    to say that I haven't been able to 'exclude' from the tar inclusion
    the Cache & OfflineCache directories from ~/.mozilla/firefox/*.default/
    which are the culprits I'd like to exclude.

    Werner's excellent suggestions
    Please, don't exaggerate

    A suggestion with exclude something:
    Code:
    cd /; STOR=/mnt-system/update$(date +'%m%d%H').tar.gz
    echo -e 'Compressing data; patience, this may take a little time..\n'
    tar -cz --exclude=*/Cache/* --exclude=*/OfflineCache/* \
        -f $STOR KNOPPIX-DATA/home/ KNOPPIX-DATA/etc/ \
         KNOPPIX-DATA/root/  mnt-system/boot/syslinux/syslinux.cfg

    Thanks, I needed that.

    .
    With that refinement, my backup only takes 46 Mb now.
    Thanks a heap & best regards.
