Hi,

In Odoo, When importing a database backup in Odoo.sh, the operation performs a full replacement of the existing database with the contents of the backup file. This means that the existing database is dropped, and the backup is restored in its place. It will drop the existing database, deleting all its contents, including tables, data, and schema and a new empty database is created with the same name as the original one and the backup file is imported into the new database, replacing the entire database schema and data.

Thanks.
