powdb_backup/lib.rs
1//! Physical backup, restore, and point-in-time recovery for PowDB.
2//!
3//! Supports full snapshots ([`full_backup`]) and incremental (differential)
4//! backups against a full base ([`incremental_backup`]). Heap files use
5//! page-LSN deltas; B+tree index files are copied as opaque whole artifacts.
6//! Restore rebuilds a data directory from a full backup ([`restore()`]), or
7//! chains a full base plus ordered increments for coarse point-in-time
8//! recovery ([`restore_chain`]). [`RestoreSyncMode`] controls whether a
9//! restored copy strips, preserves, or forks the source's sync identity, and
10//! [`bootstrap_replica_from_full_backup`] seeds a sync replica from a backup.
