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.

   optional arguments
       --tar-filter
              filter program to pipe data through

       -s, --stats
              print statistics for the created archive

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

       --filter STATUSCHARS

       -c SECONDS, --checkpoint-interval SECONDS
              write checkpoint every SECONDS seconds (Default: 1800)

       --chunker-params PARAMS
              specify the chunker parameters (ALGO, CHUNK_MIN_EXP, CHUNK_MAX_EXP, HASH_MASK_BITS,
              HASH_WINDOW_SIZE). default: buzhash,19,23,21,4095

       -C COMPRESSION, --compression COMPRESSION
              select compression algorithm, see the output of the "borg help compression" command
