Enhancements to the zfs send Command

Solaris 10 10/08 Release: This release includes the following enhancements to the zfs send command. Using this command, you can now perform the following tasks:

• Send all incremental streams from one snapshot to a cumulative snapshot. For example:

  # zfs list NAME USED AVAIL REFER MOUNTPOINT pool 428K 16.5G 20K /pool pool/fs 71K 16.5G 21K /pool/fs pool/fs@snapA 16K - 18.5K - pool/fs@snapB 17K - 20K - pool/fs@snapC 17K - 20.5K - pool/fs@snapD 0 - 21K - # zfs send -I pool/fs@snapA pool/fs@snapD > /snaps/fs@combo

  This syntax sends all incremental snapshots between fs@snapA to fs@snapD to fs@combo.

• Send an incremental stream from the original snapshot to create a clone. The original snapshot must already exist on the receiving side to accept the incremental stream. For example:

  # zfs send -I pool/fs@snap1 pool/clone@snapA > /snaps/fsclonesnap-I . . # zfs receive -F pool/clone < /snaps/fsclonesnap-I

• Send a replication stream of all descendent file systems, up to the named snapshots. When received, all properties, snapshots, descendent file systems, and clones are preserved. For example:

  # zfs send -R pool/fs@snap > snaps/fs-R

  For an extended example, see Example 7–1.

• Send an incremental replication stream. For example:

  # zfs send -R -[iI] @snapA pool/fs@snapD

  For an extended example, see Example 7–1.
