Commands to Create .tar Backup and Copy Them from Container to Host
Backing Up
1. Create a .tar Backup Inside the Container:
tar -cvzf odoo_backup.tar.gz -C /var/lib odoo
1. Copy the Backup from Container to Host:
docker cp :/path/to/odoo_backup.tar.gz /path/on/host
Commands to Copy Backups to Another Container and Restore/Import
Restoring
1. Copy the Backup from Host to Another Container:
docker cp /path/on/host/odoo_backup.tar.gz
:/path/in/container
1. Restore the Backup Inside the Container:
tar -xvzf /path/in/container/odoo_backup.tar.gz -C /var/lib
Automate the Process Using a Script and Cron
You can create a shell script to automate the backup process and then schedule it with Cron.
backup-odoo.sh
#!/bin/bash
# Variables
CONTAINER_ID="your-container-id"
DB_CONTAINER_ID="your-db-container-id"
HOST_PATH="/path/on/host"
CONTAINER_PATH="/path/in/container"
# Database Backup
docker exec $DB_CONTAINER_ID pg_dump -U odoo your_database > $HOST_PATH/odoo_db_backup.sql
# Filestore Backup
docker exec $CONTAINER_ID tar -cvzf $CONTAINER_PATH/odoo_backup.tar.gz -C /var/lib odoo
docker cp $CONTAINER_ID:$CONTAINER_PATH/odoo_backup.tar.gz $HOST_PATH
# Optional: Remove old backups, keeping last 3
find $HOST_PATH -type f -name '*.tar.gz' -mtime +3 -exec rm {} \\\\;
find $HOST_PATH -type f -name '*.sql' -mtime +3 -exec rm {} \\\\;
echo "Backup completed successfully!"

Conclusion
Docker provides powerful tools for running and managing containers, but understanding how to properly backup and restore data is crucial. By implementing these steps and techniques, you can create a robust and automated backup strategy for your Dockerized Odoo instance. Regular backups ensure that your system can be restored to a previous state if needed, providing security and peace of mind for your business operations.
Investing time to understand and implement this strategy can pay off in long-term stability and reliability, making Docker a viable and efficient platform for hosting Odoo or other similar applications.
