How does Traveller differ from Snapshots and Backups?
Most other solutions, even some that claim to be CDP, rely upon snapshots — point in time data captures at intervals within the continuum. The primary problems with relying upon snapshots (backups are a form of snapshot) are data loss and uncertainty. Because they capture only points within the continuum and not the continuum itself, states that existed between those points are lost and cannot be recovered. High risk guesswork ensues. The user must guess how many snapshots or backups to schedule and at what times to take them within any given time frame. This is akin to photographing a sporting event by setting your camera in advance of the event to automatically take photographs at specified intervals. You may be able to avoid taking a bunch of photographs during halftime, but for the most part you have got to hope you are lucky enough to capture the action you want. The gap problem is exacerbated because of the relationship between the growing volume of data and the time it takes to
