NAME¶

barman-wal-restore - 'restore_command' based on Barman's get-wal

SYNOPSIS¶

barman-wal-restore [OPTIONS] BARMAN_HOST SERVER_NAME WAL_NAME WAL_DEST

DESCRIPTION¶

This script can be used as a 'restore_command' for PostgreSQL servers, retrieving WAL files using the 'get-wal' feature of Barman. An SSH connection will be opened to the Barman host. barman-wal-restore allows the integration of Barman in PostgreSQL clusters for better business continuity results.

This script and Barman are administration tools for disaster recovery of PostgreSQL servers written in Python and maintained by EnterpriseDB.
