Bash script to archive different files and folders into a single folder which will be named using current timestamp

I use this script to back up files that are created in different locations. I feel easy to collect all the related files and folders to compress and save them as a single zip archive which is named as per the current date and time.

#!/bin/bash

# this program creates a zip archive of myFolder(containing files and folders), file1 , file2 , file3 and file4 and puts the archive in myOpDir. The name of the final zip archive will be given by the current timestamp. For eg : final_20111220_103015.zip

#create a directory for putting all the files

myFolder="/home/user/Desktop/myFolderWithContents"

myOpDir="/home/user/Desktop/myFinalDir"

file1="/home/user/Desktop/test.tcl"
file2="/home/user/Desktop/test.dump.xml"
file3="/home/user/Desktop/myDir/test.txt"
file4="/home/user/Desktop/myDir/test.txt.xml"

mkdir $myOpDir/temp

# copy the files and folder to to temp dir
cp -r $myFolder $myOpDir/temp/`

cp $file1 $myOpDir/temp/test.tcl
cp $file2 $myOpDir/temp/test.dump.xml

cp $file3 $myOpDir/temp/test.txt
cp $file4 $myOpDir/temp/test.txt.xml

#Now compress all files in a single archive

cd $myOpDir/temp/

for FILE in `ls`;do
zip -r final_`date +%Y%m%d_%H%M%S`.zip $FILE
done

cp final_`date +%Y%m%d_%H%M%S`.zip ../

cd ..

rm -r $myOpDir/temp
