NAME

zstream — manipulate zfs send streams

SYNOPSIS

DESCRIPTION

The zstream utility manipulates zfs send streams, which are the output of 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.

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.
