The default database for Odoo is the PostgreSQL database,
PG is a very powerful database and a trend in the future.
For Odoo's data backup, Odoo provides its own backup method,
1. From the foreground page. Enter the Odoo app access address, for example: 192.168.1.188:8069/web/database/manager can directly select the database you need, make manual copy, backup, and delete.
2. The Odoo app community also provides some third-party backup modules that are of interest to search by themselves.
3. From the database level, that is, follow the backup recovery of the regular database to operate.
One thing to note here is that for a single-instance, non-SaaS architecture, the Odoo program can be handled in the normal way of the database.
However, for the Odoo application of the SaaS architecture, you need to be aware of the database ID that you backed up, and if you can restore the database, it will also correspond to the management ID of the main application's SaaS module!
Backup policy to be updated!
