Snapshots are performed on a per-collection basis and consist in a `tar` archive file containing the necessary data to restore the collection at the time of the snapshot.
Snapshots are created individually for each node in a collection, resulting in a `tar` archive file that holds the data needed to restore that collection at the snapshot time. In a distributed setup, when you have multiple nodes in your cluster, you must create snapshots for each node separately when dealing with a single collection.
Therefore, in a distributed deployment, a snapshot of a collection consists of multiple `tar` archive files, with one file for each collection node.
This feature can be used to archive data or easily replicate an existing deployment.

## Store snapshots
The target directory used to store generated snapshots is controlled through the [configuration](../../guides/configuration) or using the ENV variable: `QDRANT__STORAGE__SNAPSHOTS_PATH=./snapshots`.
You can set the snapshots storage directory from the [config.yaml](https://github.com/qdrant/qdrant/blob/master/config/config.yaml) file. If no value is given, default is `./snapshots`.

Single deployment is simpler, you can recover any collection on the start-up and it will be immediately available in the service.
Restoring snapshots is done through the Qdrant CLI at startup time.
