Backup Directory Script

This script is designed to back up a specified directory to a designated backup location. It also includes options for error logging and deleting old backups.

Features

• Backs up a specified source directory to a specified backup directory.
• Logs errors during the backup process to a log file.
• Optionally deletes backups older than 30 days.

Prerequisites

• The script must be run as the root user.

Usage

1. Clone the repository or download the script:

   git clone https://github.com/sakiphan/system-backup-directory-bash.git
   cd system-backup-directory-bash

2. Make the script executable:

   chmod +x backup_directory.sh

3. Run the script manually:

   sudo ./backup_directory.sh

   You will be prompted to enter the source directory and the backup directory. The script will then perform the backup and log any errors.

Example

Enter the source directory to backup: /home/user
Enter the backup directory: /backup
Backing up directory: /home/user
Backup completed successfully: /backup/backup_YYYYMMDD_HHMMSS.tar.gz
Do you want to delete backups older than 30 days? (y/n): y
Old backups deleted.
Backup process completed.

Automating with Cron

To run the script at regular intervals, create a cron job. For example, to run it every Sunday at 4 AM:

1. Edit the cron job file:

   sudo crontab -e

2. Add the following line to the file:

   0 4 * * 0 /path/to/backup_directory.sh

   Replace /path/to/backup_directory.sh with the full path to your script.

Error Logging

If any errors occur during the backup process, they will be logged to a log file in the backup directory. The log file will be named backup_errors_YYYYMMDD_HHMMSS.log.

Cleaning Up Old Backups

The script includes an option to delete backups older than 30 days. You will be prompted to confirm whether you want to delete old backups.
