Struct BackupManifest

Fields

format_version: u16

epoch: u64

created_unix_nanos: u64

database_id: Option<DatabaseId>

Database identity (spec 10.7). Derived from the persisted replication identity (_meta/replication_id, 32 CSPRNG bytes created on first open): the DatabaseId is its first 16 bytes. The derivation is deterministic, stable across backups of one database, and travels with the backup because the marker file is part of the copied file set. None only when the source directory lacks the marker (a database never opened by a replication-aware binary); backup never invents or persists a fresh identity.

catalog_version: u64

Catalog command state-machine version at the backup boundary (S1F). 0 means “unknown”: pre-1G manifests, legacy catalogs, and encrypted catalogs whose bytes cannot be decoded here without the database passphrase.

snapshot_unix_micros: u64

Snapshot wall clock in HLC physical units (microseconds since the UNIX epoch), captured at manifest creation right after the commit boundary was copied. 0 means “unknown” (pre-1G manifests). The exact boundary nanoseconds remain available to the caller through BackupReport::boundary_unix_nanos.

open_generation: u64

WAL open generation scoping epoch, read from _meta/generation. Together (epoch, open_generation) is the log continuation position: the durable commit watermark plus the generation that scopes the WAL record sequence it refers to. 0 means “unknown” (pre-1G manifests or a missing sidecar).

encryption: Option<BackupEncryptionMetadata>

Encryption metadata; None identifies a plaintext backup.

files: Vec<BackupFile>
