.SH NAME
|
|
borg-import-tar \- Create a backup archive from a tarball
|
|
.SH SYNOPSIS
|
|
.sp
|
|
borg [common options] import\-tar [options] ARCHIVE TARFILE
|
|
.SH DESCRIPTION
|
|
.sp
|
|
This command creates a backup archive from a tarball.
|
|
.sp
|
|
When giving \(aq\-\(aq as path, Borg will read a tar stream from standard input.
|
|
.sp
|
|
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:
|
|
.INDENT 0.0
|
|
.IP \(bu 2
|
|
\&.tar.gz or .tgz: gzip \-d
|
|
.IP \(bu 2
|
|
\&.tar.bz2 or .tbz: bzip2 \-d
|
|
.IP \(bu 2
|
|
\&.tar.xz or .txz: xz \-d
|
|
.IP \(bu 2
|
|
\&.tar.zstd: zstd \-d
|
|
.IP \(bu 2
|
|
\&.tar.lz4: lz4 \-d
|
|
.UNINDENT
|
|
.sp
|
|
Alternatively, a \-\-tar\-filter program may be explicitly specified. It should
|
|
read compressed data from stdin and output an uncompressed tar stream on
|
|
stdout.
|
|
.sp
|
|
Most documentation of borg create applies. Note that this command does not
|
|
support excluding files.
|
|
.sp
|
|
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.
|
|
.sp
|
|
A \fB\-\-sparse\fP option (as found in borg create) is not supported.
|
|
.sp
|
|
import\-tar reads POSIX.1\-1988 (ustar), POSIX.1\-2001 (pax), GNU tar, UNIX V7 tar
|
|
and SunOS tar with extended attributes.
