Weekly Auto Backup Script (Bash + Rsync + SSH)

This project is a simple Bash script that automates the backup of a file (data.txt) from a local Linux machine to a remote Linux machine every week using rsync over SSH. The operation is fully logged and can be scheduled using crontab.

Project Structure

backup.sh # The main script

backup.log # Output log file generated after each run

️ Features

Secure transfer via rsync over SSH

Logs all actions and errors to a log file

️ Automatically runs weekly via cron

Success & failure status messages with timestamps

? How It Works

The script backs up this file:

/home/zeyad/Desktop/bash/data.txt

It transfers it to this remote destination:

/home/zizo/Desktop/zeyad on machine 192.168.1.45

It uses rsync with SSH and logs every operation into backup.log.

Usage

Make the script executable:

chmod +x backup.sh

Run manually (for testing):

./backup.sh

Requirements

rsync installed on both local and remote machines

SSH access to the remote machine

Correct path to data.txt

SSH password authentication enabled

️ Public key authentication is disabled intentionally in this script:

-o PreferredAuthentications=password

-o PubkeyAuthentication=no

️ Setup Weekly Backup (Crontab)

To run the backup script automatically every week, use crontab:

crontab -e

Add this line to schedule the script every Monday at 12:00 PM:

0 12 * * 1 /home/zeyad/Desktop/bash/backup.sh

Now your backup will run weekly and log the results to backup.log.
