One might be to lazy to set up or use a revision control system like CVS, SVN or git for small projects or when working on 2-3 simple files.

This script creates a directory “backup”, and places there a archive of the files in the current directory (not recursive) with an increasing number.

e.g. you start it in a Folder “Bsp-3″, it will create “backup/Bsp3-1.tar.bz2″, next time “Bsp3-2.tar.bz2″, etc.
Also cleans up duplicates, so you cannot call it too often!

Small, clean, easy. I love it!

backup-point.sh

DIRNAME=$(basename $PWD)
EXT=tar.bz2
mkdir -p backup
cleanup_unneeded(){
cd backup
FILES=*.tar.bz2
UNIQ=$(md5sum $FILES|sort|uniq --check-chars=32 | cut -d ' ' -f 3-);
for i in $FILES
do
if ! echo "$UNIQ" | grep -wq "$i"
then
echo "deleting unnecessary $i."
rm "$i"
fi
done
cd ..
}
cleanup_unneeded
for((i=1;i<200;i++)); do
FILENAME="backup/$DIRNAME-$i.$EXT"
if ! test -f "$FILENAME"; then
find  -maxdepth 1 -type f|xargs tar -cjf "$FILENAME"
echo "backup-point $i made."
cleanup_unneeded
exit
fi
done
echo '200 points reached! Clean up a bit?'
