# Consul Snapshot Decode

Command: `consul snapshot decode`

The `snapshot decode` command is used to decode an atomic, point-in-time
snapshot of the state of the Consul servers which includes key/value entries,
service catalog, prepared queries, sessions, and ACLs. The snapshot is read
from the given file and decode to `stdout` as JSON data for interpretation and
review.

-> Typically this is used with Consul self-contained Snapshot files obtained
using the [`consul snapshot`](/consul/commands/snapshot) command or [Snapshot
API](/consul/api-docs/snapshot#generate-snapshot).

The JSON stream information format:

```json
  {"Type": "SnapshotHeader", "Data": {"<json encoded snapshot header>"}}
  {"Type": "<type name>","Data": {<json encoded data>}}
  {"Type": "<type name>","Data": {<json encoded data>}}
  ...
```

## Usage

Usage: `consul snapshot decode FILE`

## Examples

To decode a snapshot from the file "backup.snap":

```shell-session
$ consul snapshot decode backup.snap
