Snapshot

Definition

A snapshot is a point-in-time copy of your reservation state — OTB, ADR, occupancy, segment splits — captured on a specific date and preserved unchanged. Think of it as photographing a plant on your windowsill every day: today’s photo is today’s state, yesterday’s photo stays as it was, and the album lets you see the growth between any two days.

What it tells you

Without snapshots, you can’t reconstruct the past. “What did we know on April 15 about June?” requires that the April 15 OTB state be preserved. Most PMS reports — and most BI tools — just show you the current state. The growth story disappears with each overwrite.

How to track it

Some PMS retain limited history; most don’t. Dedicated BI tools snapshot daily as core infrastructure (Peaqplus does this by default). Manual snapshotting via daily PMS exports works but is brittle.

Where it fits

Foundational to pickup, pace, fill curve, MAPE-based forecast accuracy, and any analysis that compares ‘now’ to ‘then.’ Peaqplus’s Time Machine view replays the OTB state from any past day — the album, made browsable.
