BARMAN_HOST SERVER_NAME WAL_NAME WAL_DEST


DESCRIPTION

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.

PARAMETERS

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
Specifies the number of WAL files to fetch in parallel. Default is 0 (disabled). When set to a value greater than 1, fetches the requested WAL file along with the next N - 1 files simultaneously. The additional files are staged in a local spool directory (see --spool-dir) so that subsequent restore requests can be served immediately from local storage.
--spool-dir
Directory used for staging extra WALs fetched when using --parallel. Default is /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.

Warning:

-z / --gzip and -j / --bzip2 options are deprecated and will be removed in the future. For WAL compression, please make sure to enable it directly on the Barman server via the compression configuration option.
