--output-directory / -o

Destination directory where barman will store the WAL file.

--peek / -p

Specify an integer value greater than or equal to 1 to retrieve WAL files from the specified WAL file up to the value specified by this parameter. When using this option, get-wal returns a list of zero to the specified WAL segment names, with one name per row.

-P / --partial

Additionally, collect partial WAL files (.partial).

-t / --test

Test both the connection and configuration of the specified Postgres server in Barman for WAL retrieval. When this option is used, the required WAL_NAME argument is disregarded.

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.
