NAME

borg-import-tar − Create a backup archive from a tarball

SYNOPSIS

borg [common options] import−tar [options] ARCHIVE TARFILE

DESCRIPTION

This command creates a backup archive from a tarball.

When giving '−' as path, Borg will read a tar stream from standard input.

By default (−−tar−filter=auto) Borg will detect whether the file is compressed based on its file extension and pipe the file through an appropriate filter:

.tar.gz or .tgz: gzip −d

.tar.bz2 or .tbz: bzip2 −d

.tar.xz or .txz: xz −d

.tar.zstd: zstd −d

.tar.lz4: lz4 −d

Alternatively, a −−tar−filter program may be explicitly specified. It should read compressed data from stdin and output an uncompressed tar stream on stdout.

Most documentation of borg create applies. Note that this command does not support excluding files.

import−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 create) is not supported.

import−tar reads POSIX.1−1988 (ustar), POSIX.1−2001 (pax), GNU tar, UNIX V7 tar and SunOS tar with extended attributes.

OPTIONS

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