borg-export-tar(1)

Name
borg-export-tar - Export archive contents as a tarball

SYNOPSIS

borg [common options] export-tar [options] ARCHIVE FILE [PATH...]

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 or .tar.zst: 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.

    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.

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

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

OPTIONS

See borg-common(1) for common options of Borg commands.

  arguments

ARCHIVE
    archive to export

FILE
    output tar file. "-" to write to stdout instead.

PATH
    paths to extract; patterns are supported

  options

--tar-filter
    filter program to pipe data through

--list
    output verbose list of items (files, dirs, ...)

  Include/Exclude options

-e PATTERN, --exclude PATTERN
    exclude paths matching PATTERN

--exclude-from EXCLUDEFILE
    read exclude patterns from EXCLUDEFILE, one per line

--pattern PATTERN
    include/exclude paths matching PATTERN

--patterns-from PATTERNFILE
    read include/exclude patterns from PATTERNFILE, one per line

--strip-components NUMBER
    Remove the specified number of leading path elements. Paths with fewer elements will be silently skipped.

EXAMPLES

    # Export as an uncompressed tar.
    $ borg export-tar /path/to/repo::Monday Monday.tar
    # Exclude some types; compress using gzip.
    $ borg export-tar /path/to/repo::Monday Monday.tar.gz --exclude '*.so'
    # Use a higher compression level with gzip.
    $ borg export-tar --tar-filter="gzip -9" testrepo::linux Monday.tar.gz
    # Export a tar, but instead of storing it on disk,
    # upload it to a remote site using curl.
    $ borg export-tar /path/to/repo::Monday - | curl --data-binary @- https://somewhere/to/POST
    # Remote extraction via "tarpipe".
    $ borg export-tar /path/to/repo::Monday - | ssh somewhere "cd extracted; tar x"
