To backup the data in the snapshot, use an appropriate utility or operating
system command to copy the contents of the snapshot to tape, or to some
other backup medium.

You now have the following options:
■ Refresh the contents of the snapshot. This creates a new point-in-time
image of the original volume ready for another backup. If synchronization
was already in progress on the snapshot, this operation may result in large
portions of the snapshot having to be resynchronized.
See “Refreshing an instant snapshot” on page 385.
■ Reattach the snapshot volume with the original volume. This operation
is not possible if the linked volume and snapshot are in different disk
groups.
See “Reattaching a linked break-off snapshot volume” on page 386.
■ Dissociate the snapshot volume entirely from the original volume. This
may be useful if you want to use the copy for other purposes such as testing
or report generation. If desired, you can delete the dissociated volume.
See “Dissociating an instant snapshot” on page 388.
■ If the snapshot is part of a snapshot hierarchy, you can also choose to
split this hierarchy from its parent volumes.
See “Splitting an instant snapshot hierarchy” on page 389.
Creating multiple instant snapshots
To make it easier to create snapshots of several volumes at the same time, the
vxsnap make command accepts multiple tuples that define the source and snapshot
volumes names as their arguments. For example, to create three instant snapshots,
each with the same redundancy, from specified storage, the following form of the
command can be used:
# vxsnap [-g diskgroup] make source=vol1/snapvol=snapvol1\
source=vol2/snapvol=snapvol2 source=vol3/snapvol=snapvol3
The snapshot volumes (snapvol1, snapvol2 and so on) must have been prepared
in advance.
See “Creating a volume for use as a full-sized instant or linked break-off snapshot”
on page 370.
The specified source volumes (vol1, vol2 and so on) may be the same volume or
they can be different volumes.
If all the snapshots are to be space-optimized and to share the same cache, the
following form of the command can be used:
