# Snapshot overview

A snapshot is a point-in-time capture of the configured Microsoft tenant state for one tenant connection.

## What a snapshot contains

Each snapshot stores:

* snapshot metadata
* run status and timestamps
* item counts
* captured configuration data
* drift summaries
* optional comment

## Snapshot statuses

Typical statuses are:

* `running`
* `success`
* `error`

If a snapshot fails, the detail page surfaces the error message.

## Snapshot detail tabs

The snapshot detail page includes:

* **Overview**
  * high-level metadata and drift summary
* **Inventory**
  * detailed configuration inventory by category
* **Export**
  * JSON export of the full snapshot payload

## Baselines

A successful snapshot can be approved as a baseline. Baselines are used as a durable comparison target for future snapshots.

This is useful when:

* you want to compare against a known approved state
* you do not want each drift review to depend only on the immediately previous snapshot

## Previous vs baseline drift

Driftmark can compare a snapshot against:

* the previous snapshot
* the current approved baseline

## Comments

Snapshots support comments so reviewers can document:

* what changed
* whether changes were expected
* remediation notes
* evidence review context
