VxVM can take an image of a volume at a given point in time. This image is called a volume snapshot.

You can also take a snapshot of a volume set.

Snapshot creation using the vxsnap command is the preferred mechanism for implementing point-in-time copy solutions in VxVM. Support for traditional third-mirror snapshots that are created using the vxassist command may be removed in a future release.

To recover from the failure of instant snapshot commands, see the Veritas InfoScale Troubleshooting Guide.
