BookStack Backup Automation Every 6 Hours

Creating a script to automate your BookStack backup process is definitely feasible, even with the requirement to input a password for the ` mysqldump ` command. You can streamline the process with a script that bundles these steps together. However, automating password input for ` mysqldump ` securely can be a bit tricky due to security concerns with storing plaintext passwords. Here’s a general approach to handle this: 

 ### Automating ` mysqldump ` Without Exposing Passwords 

 Instead of embedding the MySQL password in the script, you can use a configuration file (` ~/.my.cnf `) for the user running the backup. This file stores the MySQL credentials and allows ` mysqldump ` to access them without requiring them to be input manually or stored in the script. 

 1. Create the MySQL Configuration File: 

  On the user’s home directory that will run the backup, create a file named ` .my.cnf `: 

 sudo nano ~/.my.cnf 

  Add the following content, replacing `your_password` with the MySQL root password: 

  [mysqldump]

user=root

password=your_password 

 Secure the file by setting its permissions so that only the owner can read and write: 

 chmod 600 ~/.my.cnf 

 Writing the Backup Script 

 Now, let’s create a script that encompasses your backup steps. The script will not require manual password entry due to the use of the `.my.cnf` configuration. 

 #!/bin/bash

# Variables

BACKUP_DIR="/mnt/localcloud/BookStack_Backups"

DATE=$(date +"%m_%d_%Y")

DB_BACKUP_FILE="bookstack_db_backup_$DATE.sql"

FILES_BACKUP_FILE="bookstack_files_backup_$DATE.tar.gz"

# Navigate to the projects directory

cd /var/www/bookstack

# Database backup

mysqldump bookstack | sudo tee "$BACKUP_DIR/$DB_BACKUP_FILE" > /dev/null

# Backup the Storage / Uploads / Themes / Public

sudo tar -czvf "$BACKUP_DIR/$FILES_BACKUP_FILE" .env public/uploads storage/uploads themes

echo "Backup completed and stored in $BACKUP_DIR" 

 Explanation: This script backs up the database using ` mysqldump `, directing the output to a file in your network share directory. It also creates a tarball of your specified directories and stores it alongside the database backup. The `date` command is used to append the current date to the filenames, automating the date management process. 

 Running the Script Automatically 

 To run this script automatically, you can use ` cron `: 

 1. Open the current user’s crontab: 

 crontab -e 

 2. **Add a cron job to run the script at your desired frequency.** For example, to run it daily at 1 AM: 

 0 1 * * * /path/to/your/backup_script.sh 

 3. Here's how to do it every 6 hours, and also pointing at the right path to my installation of bookstack. 

 0 */6 * * * /home/zippyb/backupbookstack.sh 

 

 Replace `/path/to/your/backup_script.sh` with the actual path to your script. Make sure the script is executable (`chmod +x backup_script.sh`). 

 Important Considerations 

 - Security: Ensure that the `.my.cnf` file and the backup script are securely stored and accessible only by trusted users. - Backup Rotation : This script doesn’t handle backup rotation (deleting old backups to save space). You might want to add logic to delete backups older than a certain number of days. - Testing : Test your backup and restoration process to ensure it works as expected before relying on it for production use. 

 This setup provides a basic framework. Depending on your specific needs and environment, you may need to adjust paths, permissions, or other details.
