Deduplicated send streams can be generated by using the
|
|
.Nm zfs Cm send Fl D
|
|
command.
|
|
The ability to send deduplicated send streams is deprecated.
|
|
In the future, the ability to receive a deduplicated send stream with
|
|
.Nm zfs Cm receive
|
|
will be removed.
|
|
However, deduplicated send streams can still be received by utilizing
|
|
.Nm zstream Cm redup .
|
|
.Pp
|
|
The
|
|
.Nm zstream Cm redup
|
|
command is provided a
|
|
.Ar 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:
|
|
.Dl # Nm zstream Cm redup Pa DEDUP_STREAM_FILE | Nm zfs Cm receive No …
|
|
.Bl -tag -width "-D"
|
|
.It Fl v
|
|
Verbose.
|
|
Print summary of converted records.
