Değerli yorumun için çok teşekkür ederim hocam. Evet buna benzer bir çözüm yolu ile sorunumu çözdüm.

#!/bin/bash
####################################
#
# Backup to NFS mount script.
#
####################################
# What to backup.
backup_files="/var/www/SITE_ADI"
# Where to backup to.
dest="/var/web_backup"
# Create archive filename.
day=$(date +%A)
hostname=$(hostname -s)
archive_file="$hostname-$day.tgz"
# Print start status message.
echo "Backing up $backup_files to $dest/$archive_file"
date
echo
# Backup the files using tar.
tar czf $dest/$archive_file $backup_files
# Print end status message.
echo
echo "Backup finished"
date
# Long listing of files in $dest to check file sizes.
ls -lh $dest

Kodunu cronjobla ile otomatikleştirdim.

Çok teşekkür ederim.
