Backup

This Bash script provides a robust solution for backing up server directories and a MySQL database. It reads configuration settings from an external file (backup.conf), performs the backups, logs the process, and securely encrypts the backup files.

Prerequisites

Before you begin, ensure you have the following installed and configured on your system:

• Bash Shell: Available on Linux and UNIX-like operating systems.
• MySQL Server: Needed for database backups.
• OpenSSL: Required for encrypting the backup files.
• tar: Utility for archiving directories.
• Access Permissions: Ensure the script has the necessary permissions to access the directories and databases you intend to back up.

Configuration

Set up your backup configuration by editing the backup.conf file. Adjust the file paths, database credentials, and other settings according to your specific needs.

Configuration File Template

# Database settings
DB_USER=root
DB_PASSWORD=password
DB_NAME=my_database

# Backup settings
ENCRYPTION_PASSWORD=my_secure_password
BACKUP_ROOT_DIR=/path/to/backup
SOURCE_DIRS=/home/user/data,/home/user/docs

# Log file location
LOG_FILE=/path/to/backup.log

Installation

1. Download the Script: Clone this repository or directly download the backup.sh and backup.conf files to your server.

2. Set File Permissions: Secure the script and configuration file:

   chmod 700 backup.sh
   chmod 600 backup.conf

3. Configure the backup.conf File: Ensure the configuration file is placed either in the same directory as backup.sh or specify its location in the script.

Usage

Execute the script with the following command:

./backup.sh

Automate with Cron

To automate the backup process, add a cron job:

crontab -e

Insert the following line to run the backup daily at 2 AM:

0 2 * * * /path/to/backup.sh > /dev/null 2>&1

Security Considerations

• Protect Sensitive Data: Ensure the backup.conf is kept secure, as it contains sensitive information.
• Restrict Access: Limit access to the script, configuration file, and backup data to trusted users only.
• Regular Testing: Frequently test the backup and restore process to confirm the integrity and recoverability of the data.

Monitoring and Logs

Monitor the backup process through the log file specified in backup.conf. Check this file regularly for any errors or confirmations of successful backups:

cat /path/to/backup.log
