FaunaDB Backup Restore ↔︎ Index Rebuild Timing: Uncertain Warm‑Up Period

Goal

Determine whether indexes are immediately usable after restoring a FaunaDB backup and how to confirm that the recovered data matches the original state.

Context

FaunaDB’s Backup API creates immutable snapshots stored in the object store. The fauna backup restore command recreates a database instance with the snapshot’s contents. The original database remains unchanged unless explicitly overwritten. No built‑in verification step is provided; users must run custom queries to validate data integrity.

Unresolved Behavior

Documentation does not clarify whether indexes are rebuilt automatically during restore, or if a warm‑up period is required before queries can use them. This uncertainty can affect application availability and test planning.

Specific Questions

• Does FaunaDB rebuild all indexes automatically during the restore process?
• Is there a documented warm‑up period after restore before indexes become fully queryable?
• What validation queries or checksums are recommended to confirm that restored data matches the source snapshot?
