Here's a script I run that does that... in fact it does a number of stupid find
tricks...

I ran one today where I wanted to look for all files modified around 
December 1, it looked like find . \( -mtime +75 -a -mtime -85 \) -print


#!/bin/sh

#	Do backups using tar
#		first clean up files that should not be backed up (like deleted mail)
#		then create a list of files newer than the last backup
#		save the current time by touching a file
#		tar the listed file to a compressed tar file

#	Clean up extraneous files

echo "Cleaning up mail"
find /home/ajackson/Mail \( -name ',[0-9]*' \) -ls -exec rm {} \;
rm ~ajackson/.bak

#	first find all files newer than the .last_backup file 
#	that are not directories
#	Do not look in mounted filesystems (this prevents looking at the
#	DOS partitions

echo "Running find command"
/bin/rm -f /tmp/backups
/bin/rm -f /home/ajackson/.maildir/new/*
##find / -mount -newer /.last_backups ! -type d  ! -name "backtar.gz" \( -regex "^/var/*" -o -regex "^/usr/local/*" -o -regex "^/opt/*"  \) -a -prune -fprint /tmp/backups_all
#find / \( -regex "^/var/*" -o -regex "^/usr/local/*" -o -regex "^/opt/*"  \) -a -prune -o -mount -newer /.last_backups ! -type d  ! -name "backtar.gz" -fprint /tmp/backups_all
find /etc -newer /.last_backups ! -type d  ! -name "backtar.gz" -fprint /tmp/backups_all_etc
find /home/ajackson -newer /.last_backups ! -type d  ! -name "backtar.gz" ! -name "*.wav" ! -name "*.mp3" ! -name "*.ogg" ! -name "*.jpg" ! -name "*.gif" -fprint /tmp/backups_all_home
cat /tmp/backups_all_etc /tmp/backups_all_home > /tmp/backups_all

#	remove stuff from file that doesn't get backed up

cat /tmp/backups_all | grep -i -v -E 'cache'  | grep -i -v 'glameswap' | grep -i -v 'tif' | grep -v 'trash' | grep -v 'backup' | grep -v 'queue' | grep -v 'thumbnails' > /tmp/backups

#	reset .last_backups file

touch /.last_backups

#	Create tar file

tar -cvzf /backtar.gz --files-from /tmp/backups

cp /backtar.gz /archive/backups/`date +%y%m%d:%H%M`.gz

echo "Tar file creation done. File is "
echo "`ls -als /backtar.gz`"

echo "File copied to /archive/backups/`date +%y%m%d:%H%M`.gz "
