Hi,

If you don't spent time with script you have backup-manager.
I have a howto on it.

Backup manager can create backup of file svn mysql on the number of day you define and can also push those file to a another place over FTP,ssh.
by default all archive are put on /var/archives.

How about something like this...... 

#!/bin/bash 

# This script makes a backup of the files on the primary server directory. 

# Change the values of the variables to make the script work: 
BACKUPDIR=/data/ 
BACKUPFILES=*.cdf 
GZTARFILE=/var/tmp/data_$(date +%F).tar.gz 
SERVER=mcastasp1 
REMOTEDIR=/home/admin/DATA_BKP 
LOGFILE=/home/admin/DATA_BKP/backup.log 
CLEANUP=/home/admin/DATA_BKP 

cd $BACKUPDIR 

# This creates the archive 
tar zcf $GZTARFILE $BACKUPFILES > /dev/null 2>&1 

# Create Remote backup Directory 
ssh $SERVER 'mkdir -p /home/admin/DATA_BKP' 

# Copy the file to another host - we have ssh keys for making this work without intervention. 
scp $GZTARFILE $SERVER:$REMOTEDIR > /dev/null 2>&1 

# Redirect errors because this generates some if the archive 
# does not exist. 
rm $GZTARFILE 2> /dev/null 

# Create a timestamp in a logfile. 
date >> $LOGFILE 
echo backup succeeded >> $LOGFILE 

# Clean up remote server and leave 7 days of backup files 
ssh $SERVER 'find /home/admin/DATA_BKP/ -follow -name 'data_*' -ctime +7 -exec rm {} \;'

Subject: [CentOS] Bash script for backup 

Hello guyz! 

I'm new here, and this is my very first truble... 

I need a script that will backup & compress the folder /media/system in 
the folder /media/backups 

But that's not the problem, I need that only the last 7 backups (last 7 
days, yeah I know, cronjob...) will stay in that folder... 

The script need: 
1 - Compress folder /media/system 
2 - Store in /media/backups 
3 - Name the compressed backup like day_month_year.tar.gzip 
4 - Check the other backups and delete backups older than 7 days.. 

Can some one help me? 

Tanks! 
This is what I want! But there is just one problem, I don't need SSH, I just need a folder on the local machine that will have the 7 days backup, then I'll use rsync for on remote server, but this part I already have. How can I use this script whitout the SSH?
