#ptrack
#PTRACK is a block-level incremental backup engine for PostgreSQL.

## Overview

Ptrack is a block-level incremental backup engine for PostgreSQL.You can [effectively use](https://postgrespro.github.io/pg_probackup/#pbk-setting-up-ptrack-backups) `ptrack` engine for taking incremental backups with [pg_probackup](https://github.com/postgrespro/pg_probackup) backup and recovery manager for PostgreSQL.

It is designed to allow false positives (i.e. block/page is marked in the `ptrack` map, but actually has not been changed), but to never allow false negatives (i.e. loosing any `PGDATA` changes, excepting hint-bits).

Currently, `ptrack` codebase is split between small PostgreSQL core patch and extension. All public SQL API methods and main engine are placed in the `ptrack` extension, while the core patch contains only certain hooks and modifies binary utilities to ignore `ptrack.map.*` files.
