Description
~~~~~~~~~~~

This command creates a tarball from an archive.

When giving '-' as the output FILE, Borg will write a tar stream to standard output.

By default (``--tar-filter=auto``) Borg will detect whether the FILE should be compressed
based on its file extension and pipe the tarball through an appropriate filter
before writing it to FILE:

- .tar.gz or .tgz: gzip
- .tar.bz2 or .tbz: bzip2
- .tar.xz or .txz: xz
- .tar.zstd: zstd
- .tar.lz4: lz4

Alternatively, a ``--tar-filter`` program may be explicitly specified. It should
read the uncompressed tar stream from stdin and write a compressed/filtered
tar stream to stdout.

Depending on the ``-tar-format`` option, these formats are created:

+--------------+---------------------------+----------------------------+
| --tar-format | Specification             | Metadata                   |
+--------------+---------------------------+----------------------------+
| BORG         | BORG specific, like PAX   | all as supported by borg   |
+--------------+---------------------------+----------------------------+
| PAX          | POSIX.1-2001 (pax) format | GNU + atime/ctime/mtime ns |
+--------------+---------------------------+----------------------------+
| GNU          | GNU tar format            | mtime s, no atime/ctime,   |
|              |                           | no ACLs/xattrs/bsdflags    |
+--------------+---------------------------+----------------------------+

A ``--sparse`` option (as found in borg extract) is not supported.

By default the entire archive is extracted but a subset of files and directories
can be selected by passing a list of ``PATHs`` as arguments.
The file selection can further be restricted by using the ``--exclude`` option.

For more help on include/exclude patterns, see the :ref:`borg_patterns` command output.

``--progress`` can be slower than no progress display, since it makes one additional
pass over the archive metadata.
