NAME¶
borg-export-tar - Export archive contents as a tarballSYNOPSIS¶
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: 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.
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
optional arguments¶
- --tar-filter
- filter program to pipe data through
- --list
- output verbose list of items (files, dirs, ...)
Exclusion options¶
- -e PATTERN, --exclude PATTERN
- exclude paths matching PATTERN
- --exclude-from EXCLUDEFILE
- read exclude patterns from EXCLUDEFILE, one per line
- --pattern PATTERN
- experimental: include/exclude paths matching PATTERN
- --patterns-from PATTERNFILE
- experimental: 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 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 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"
