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.
