Note!

The instructions for backup and upgrade of the database below are only relevant if you are using Azure Database for PostgreSQL - Flexible Server as platform database. If the platform database used is derby, the backup of the Azure Files Storage covers the database as well (assuming persistent storage of the platform is enabled).

Note!

If there are standalone ECs that are still running and writing their logs to the same EFSfile storage , whatever happens after the backup has been initiated will not be included in the backup.
