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: gzip
- .tar.bz2: bzip2
- .tar.xz: xz

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.

The generated tarball uses the GNU tar format.

export-tar is a lossy conversion:
BSD flags, ACLs, extended attributes (xattrs), atime and ctime are not exported.
Timestamp resolution is limited to whole seconds, not the nanosecond resolution
otherwise supported by Borg.

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.

See the output of the "borg help patterns" command for more help on exclude patterns.

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