Module backup 

Versioning and point-in-time recovery for hirn databases.

Wraps LanceDB’s native versioning primitives (tags, version numbers, and dataset-level checkout) into brain-wide operations. For disaster recovery, rely on infrastructure-level tools:

• S3 / GCS / Azure: object-store versioning, cross-region replication, lifecycle policies.
• Local: rsync, tar, or filesystem snapshots of the Lance directory.

Structs

RollbackReport

Result of a rollback operation.

Snapshot

A consistent snapshot across all datasets.

SnapshotReport

Result of a snapshot operation.

Functions

create_snapshot

Create a named snapshot by tagging every dataset at its current version.

list_snapshots

List all snapshots by collecting tags from every dataset and intersecting on tag name. A tag is considered a complete snapshot only when it appears on all datasets.

rollback

Roll back all datasets to the versions captured by the named snapshot tag.
