# Understanding TimeFinder SnapVX

TimeFinder SnapVX is a local replication solution that is designed to nondisruptively create point-in-time copies (snapshots) of critical data.

TimeFinder SnapVX creates snapshots by storing changed tracks (deltas) directly in the Storage Resource Pool of the source volume. With TimeFinder SnapVX, you do not need to specify a target volume and source/target pairs when you create a snapshot. If the application ever needs to use the point-in-time data, you can create links from the snapshot to one or more target volumes. If there are multiple snapshots and the application needs to find a particular point-in-time copy for host access, you can link and relink until the correct snapshot is located.
