OrientDB does not have any real backup and restore procedures, but rather they have the import/export ones. The export/import procedure is useful when you plan to upgrade your version of OrientDB. In fact, since the compatibility between different engine versions is not guaranteed, to move a database from an engine to a new one, it is recommended to do an export from the old system and an import into the new one. To import/export a database you can use both the command-line console and the OrientDB Studio.
Using the console, you will be able to export an entire database or only its schema. To do export a database fully, you have to connect as admin and execute the following command:
export database <output-file>
For example:
export database demo.json
The database is exported and gzipped. The compressed gzipped file contains a text file which has all the database info, schema, and data in JSON format. This file can be imported back into a new fresh database...
