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.
