Catalog backup

As explained in Architecting an Apache Iceberg Lakehouse

The practice of exporting, synchronizing, or otherwise backing up catalog definitions and metadata references for later restoration.

Catalog backup preserves table definitions and metadata references so an Iceberg lakehouse can recover when catalog state is lost or damaged. Catalogs are often not versioned by default, making them a weak link in disaster recovery. section 11.3.5 section 11.3

A practical catalog-backup design includes:

  • Periodically export catalog state into reproducible JSON or Avro formats. section 11.3.5
  • Synchronize Nessie branches across environments with automated fetch-and-push scripts. section 11.3.5
  • Build custom exports for Glue and REST catalogs that capture schemas, partition specifications, and metadata-location URIs. section 11.3.5
  • Schedule and validate backups, then combine them with storage replication and scripted registration or rollback procedures. section 11.3.5

Recovery-oriented export

An orchestrated workflow exports catalog definitions, verifies replicated metadata files, and retains enough information to register tables again after a catalog failure. section 11.3.5

How Architecting an Apache Iceberg Lakehouse covers it

How deep it goes
Explains export formats, catalog-specific fields, branch synchronization, validation, and scripted restoration without specifying a complete backup implementation.
Examples
Uses JSON or Avro exports, Nessie branch synchronization, and custom Glue or REST catalog exports as implementation examples.
What it assumes
Assumes familiarity with Iceberg tables and catalogs while identifying schemas, partition specifications, metadata URIs, and table registration as recovery data.
What you can do after
Operate/configure repeatable catalog recovery workflows that export state, validate replicas, and restore table registrations.
How it connects
Connects Apache Iceberg with disaster recovery, snapshots, metadata files, object storage replication, Nessie, Glue, and REST catalogs.
