Parameters:

snapshot Object name The name of the
snapshot to
duplicate.

name Object name Name of the new
snapshot to be
generated.
N Automatically
generated name.
This command duplicates an existing snapshot. The newly created snapshot is
initially locked for changes and is associated with the master volume of the
existing snapshot. The content of the newly created snapshot is identical to the
content of the source snapshot.
It is useful to duplicate a snapshot before unlocking it for write operations. The
duplicate snapshot can be used as a logical backup of the data in case the write
operation caused logical data corruption.
Upon successful completion of the command, a new duplicate snapshot is created.
The duplicated snapshot is identical to the source snapshot. It has the same
creation time and behaves as if it was created at the exact same moment that the
source snapshot was created from the same master volume.
The duplicate snapshot's name is either automatically generated from its master
volume's name or provided as a parameter. It can later be changed without
altering its modification state.
A snapshot can be duplicated multiple times. A duplicated snapshot can be the
source for further duplications.
Example:
snapshot_duplicate snapshot=DBVolume.snapshot1 name=DBVolume.snapshot1.copy
