NAME

       zstream — manipulate ZFS send streams

SYNOPSIS

       zstream dump [-Cvd] [file]
       zstream redup [-v] file
       zstream token resume_token

DESCRIPTION

       The zstream utility manipulates ZFS send streams output by the zfs send command.

       zstream dump [-Cvd] [file]
         Print  information  about  the  specified  send  stream, including headers and record counts.  The send
         stream may either be in the specified file, or provided on standard input.

         -C  Suppress the validation of checksums.

         -v  Verbose.  Print metadata for each record.

         -d  Dump data contained in each record.  Implies verbose.

         The zstreamdump alias is provided for compatibility and is equivalent to running zstream dump.

       zstream token resume_token
         Dumps zfs resume token information

       zstream redup [-v] file
         Deduplicated send streams can be generated by using the zfs send  -D  command.   The  ability  to  send
         deduplicated  send  streams  is  deprecated.  In the future, the ability to receive a deduplicated send
         stream with zfs receive will be removed.  However, deduplicated send streams can still be  received  by
         utilizing zstream redup.

         The  zstream  redup  command  is  provided a file containing a deduplicated send stream, and outputs an
         equivalent non-deduplicated send stream on standard output.  Therefore, a deduplicated send stream  can
         be received by running:
               # zstream redup DEDUP_STREAM_FILE | zfs receive …

         -v  Verbose.  Print summary of converted records.
