Backup and Recovery for Babelfish on FoundryDB
Babelfish stores everything in a standard PostgreSQL database (babelfish_db). Your T-SQL schemas, tables, stored procedures (compiled to PL/pgSQL internally), triggers, and views are all PostgreSQL objects underneath. This means the backup story for Babelfish is exactly the backup story for PostgreSQL: pgbackrest, WAL archiving, and point-in-time recovery.
This post documents how backups work on a live Babelfish 4.8.0 instance, using confirmed results from FoundryDB staging.
