# Restoring data from a snapshot into clusters
<a name="data-tiering-enabling-snapshots"></a>

You can restore a snapshot to a new cluster with data tiering enabled using the (Console), (Amazon CLI) or (MemoryDB API). When you create a cluster using node types in the r6gd family, data tiering is enabled. 

## Restoring data from a snapshot into clusters with data tiering enabled (console)
<a name="data-tiering-enabling-snapshots-console"></a>

To restore a snapshot to a new cluster with data tiering enabled (console), follow the steps at [Restoring from a snapshot (Console)](snapshots-restoring.md#snapshots-restoring-CON)

Note that to enable data-tiering, you need to select a node type from the r6gd family.

## Restoring data from a snapshot into clusters with data tiering enabled (Amazon CLI)
<a name="data-tiering-enabling-snapshots-cli"></a>

When creating a cluster using the Amazon CLI, data tiering is by default used by selecting a node type from the r6gd family, such as *db.r6gd.xlarge* and setting the `--data-tiering` parameter. 

You cannot opt out of data tiering when selecting a node type from the r6gd family. If you set the `--no-data-tiering` parameter, the operation will fail.

For Linux, OS X, or Unix:

```
aws memorydb create-cluster \
   --cluster-name my-cluster \
   --node-type db.r6gd.xlarge \
   --engine valkey 
   --acl-name my-acl \
   --subnet-group my-sg \
   --data-tiering \
   --snapshot-name my-snapshot
```

For Windows:

```
aws memorydb create-cluster ^
   --cluster-name my-cluster ^
   --node-type db.r6gd.xlarge ^
   --engine valkey ^
   --acl-name my-acl ^
   --subnet-group my-sg ^
   --data-tiering ^
   --snapshot-name my-snapshot
```

After running this operation, you will see a response similar to the following:
