Restore testing inferred metadata - Amazon Backup
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Restore testing inferred metadata

Restoring a recovery point requires restore metadata. To perform restore tests, Amazon Backup automatically infers metadata that is likely to result in a successful restore. The command get-restore-testing-inferred-metadata can be used to preview what Amazon Backup will infer. The command get-restore-job-metadata returns the set of metadata inferred by Amazon Backup. Note that for some resource types (Amazon FSx), Amazon Backup is not able to infer a complete set of metadata.

Inferred restore metadata is determined during the restore testing process. You can override certain restore metadata keys by including the parameter RestoreMetadataOverrides in the body of RestoreTestingSelection. Note that key values are not case sensitive.

Each supported resource has both inferred restore metadata keys and values, and overridable restore metadata keys. Only RestoreMetadataOverrides key value pairs or nested key value pairs marked with required for successful restore are necessary to include; the others are optional.
