Creating an automated backup script for Koha, an open-source Integrated Library System (ILS), requires some careful consideration. Here's a basic example of a shell script that you can schedule to run regularly using cron on a Linux system. This script will backup your Koha database and files to a specified directory.
Firstly, ensure you have the necessary permissions to access the Koha database. You may need to adjust the username and password accordingly in the script.
```bash
#!/bin/bash
# Koha backup script
# Database credentials
DB_USER="your_database_username"
DB_PASSWORD="your_database_password"
DB_NAME="your_koha_database_name"
# Backup directory
BACKUP_DIR="/path/to/backup/directory"
# Date for backup file
DATE=$(date +"%Y-%m-%d")
# Dump Koha database
mysqldump -u $DB_USER -p$DB_PASSWORD $DB_NAME > $BACKUP_DIR/$DB_NAME-$DATE.sql
# Backup Koha files
tar czf $BACKUP_DIR/koha-files-$DATE.tar.gz /path/to/your/koha/installation
# Optional: Delete older backups to save space
#find $BACKUP_DIR -type f -name '*.tar.gz' -mtime +7 -exec rm {} \;
#find $BACKUP_DIR -type f -name '*.sql' -mtime +7 -exec rm {} \;
echo "Backup completed"
```
Replace `"your_database_username"`, `"your_database_password"`, `"your_koha_database_name"`, and `"/path/to/backup/directory"` with your actual database credentials and desired backup directory.
Make sure to give execute permission to this script:
```bash
chmod +x koha_backup.sh
```
You can then schedule this script to run daily or weekly using cron:
```bash
crontab -e
```
Then add a line like this to schedule it to run every day at 2 AM:
```bash
0 2 * * * /path/to/koha_backup.sh
```
This script will dump your Koha database to a `.sql` file and compress your Koha files into a `.tar.gz` archive, appending the current date to the filenames.
Adjust the backup frequency, retention policy, and any other parameters to fit your specific requirements. Additionally, make sure to test the script in a safe environment before deploying it to production.
