Very simple script to dump a named Odoo database into restorable zip file (with filestore)

odoo_backup.py

import base64
import os.path
import sys
from datetime import datetime
from xmlrpc.client import ServerProxy

full_host = os.getenv("ODOO_HOST", "http://localhost:8069")
master_pwd = os.getenv("ODOO_MASTER_PASSWORD")

if master_pwd is None:
    exit("You must set ODOO_MASTER_PASSWORD environment variale, and probably ODOO_HOST (https://odoo_server.com:port)")

try:
    _, db_name, target_dir = sys.argv
except ValueError as e:
    print("Usage: odoo_backup.py <db_to_backup> <target_dir>")
    exit(-1)

full_path = os.path.abspath(target_dir)
if not os.path.exists(full_path):
    print("Missing target directory, try to create it")
    os.mkdir(full_path)

date_str = datetime.now().strftime("%Y-%m-%d_%H-%M-%S")
full_path = "{full_path}/{db_name}_{date_str}.zip".format(full_path=full_path, db_name=db_name, date_str=date_str)

if os.path.exists(full_path):
    sys.exit("The target file already exists !")

p = ServerProxy('{}/xmlrpc/db'.format(full_host))
with open(full_path, "wb") as f:
    f.write(base64.b64decode(p.dump(master_pwd, db_name, "zip")))

Please don't use this ! For a big enough database, the download will fail due to Xml-RPC timeout which is difficult to increase. Simply perform a POST request:

wget --post-data "master_pwd=$ODOO_MASTER_PASSWORD&name=$ODOO_DATABASE_NAME&backup_format=zip" -O default_$(date +%Y-%m-%d_%H-%M-%S).zip -T 300 $ODOO_HOST/web/database/backup
