    BARMAN_HOST SERVER_NAME WAL_NAME WAL_DEST

This script serves as a restore_command for Postgres servers, enabling the retrieval of WAL files through Barman's get-wal feature. It establishes an SSH connection to the Barman host and facilitates the integration of Barman within Postgres clusters, enhancing business continuity.

Exit Statuses are:

• 0 for SUCCESS.
• 1 for remote get-wal command FAILURE, likely because the requested WAL could not be found.
• 2 for ssh connection FAILURE.
• Any other non-zero for FAILURE.

SERVER_NAME

The server name configured in Barman for the Postgres server from which the WAL file is retrieved.

BARMAN_HOST

The host of the Barman server.

WAL_NAME

The value of the '%f' keyword (according to restore_command).

WAL_DEST

The value of the '%p' keyword (according to restore_command).

-h / --help

Display a help message and exit.

-V / --version

Display the program's version number and exit.

-U / --user

Specify the user for the SSH connection to the Barman server (defaults to barman).

--port

Define the port used for the SSH connection to the Barman server.

-s / --sleep

Pause for SECONDS after a failed get-wal request (defaults to 0 - no wait).

-p / --parallel

Indicate the number of files to peek and transfer simultaneously (defaults to 0 - disabled).

--spool-dir

Specify the spool directory for WAL files (defaults to /var/tmp/walrestore).

-P / --partial

Include partial WAL files (.partial) in the retrieval.

-z / --gzip

Transfer WAL files compressed with gzip.

-j / --bzip2

Transfer WAL files compressed with bzip2.

--keep-compression

If specified, compressed files will be trasnfered as-is and decompressed on arrival on the client-side.

-c / --config

Specify the configuration file on the Barman server.

-t / --test

Test the connection and configuration of the specified Postgres server in Barman to ensure it is ready to receive WAL files. This option ignores the mandatory arguments WAL_NAME and WAL_DEST.
