Batch backup folder under Linux

Working under Linux, how can I make more convenient backups of previous work? Every time we go to the command pack? The best way of course is to use the powerful shell under Linux.
Here is a simple example I wrote to back up the shell scripts for two folders floderName1 and floderName2. Each backup is distinguished by the system time at which it was backed up. You can add your own code if you need to, of course, if there are rules between these folders is better.

#!/bin/shflodername1=flodername1backupname1= $floderName 1-' Date +%y%m%d%h%m '. tar.bz2 backuppath1=/mnt/tar/$ FLODERNAME1TAR-CJVF $backupName 1 $floderName 1mv $backupName 1 $backupPath 1

flodername2=flodername2backupname2= $floderName 2-' date +%y%m%d%h%m '. tar.bz2 backuppath2=/mnt/tar/$floderName 2tar- CJVF $backupName 2 $floderName 2mv $backupName 2 $backupPath 2
