Managing elastic cluster snapshots

Manual snapshots can be taken after an elastic cluster has been created. Automated backups are created the moment the elastic cluster snapshot is created.

Note

Your elastic cluster must be in the Available state for a manual snapshot to be taken.

This section explains how you can create, view, restore from, and delete elastic cluster snapshots.

The following topics show how to perform various tasks when working with Amazon DocumentDB elastic cluster snapshots.

Creating a manual elastic cluster snapshot

In this section we explain how to create a manual elastic cluster snapshot, using either the Amazon Web Services Management Console or Amazon CLI with the following instructions.

Using the Amazon Web Services Management Console

To create a manual elastic cluster snapshot using the Amazon Web Services Management Console:

  1. Sign into the Amazon Web Services Management Console and open the Amazon DocumentDB console.

  2. In the navigation pane, choose Snapshots.

    Tip

    If you don't see the navigation pane on the left side of your screen, choose the menu icon in the upper-left corner of the navigation pane.

  3. On the Snapshots page, choose Create.

  4. On the Create cluster snapshot page, in the Cluster identifier field, choose your elastic cluster from the drop down list.

    In the Snapshot identifier field, enter a unique identifier for your elastic cluster.

    Choose Create.

    Diagram: elastic cluster create snapshot
Note

Alternatively, you can access the Create cluster snapshot dialog by going to the Clusters page, checking the box next to your cluster, then choosing Actions, then Take snapshot.

Your elastic cluster snapshot is now provisioning. This can take up to a few minutes to finish. You can view and restore from your snapshot when the status shows as Available in the Snapshots list.

Using the Amazon CLI

To create a manual elastic cluster snapshot using the Amazon CLI, use the create-cluster-snapshot operation with the following parameters:

  • --snapshot-name—Required. The name of the cluster snapshot you want to create.

  • --cluster-arn—Required. The ARN identifier of the cluster of which you want to create a snapshot.

In the following example, replace each user input placeholder with your own information.

For Linux, macOS, or Unix:

aws docdb-elastic create-cluster-snapshot \
    --snapshot-name sample-snapshot-1 \
    --cluster-arn arn:aws-cn:docdb:us-west-2:123456789012:sharded-cluster:sample-cluster

For Windows:

aws docdb-elastic create-cluster-snapshot ^
    --snapshot-name sample-snapshot-1 ^
    --cluster-arn arn:aws-cn:docdb:us-west-2:123456789012:sharded-cluster:sample-cluster

Viewing an elastic cluster snapshot

In this section we explain how to view elastic cluster snapshot information, using either the Amazon Web Services Management Console or Amazon CLI with the following instructions.

Using the Amazon CLI

To view information about a specific elastic cluster snapshot using the Amazon CLI, use the get-cluster-snapshot operation with the following parameters:

  • --snapshot-arn—Required. The ARN identifier of the snapshot for which you want information.

In the following example, replace each user input placeholder with your own information.

For Linux, macOS, or Unix:

aws docdb-elastic get-cluster-snapshot \
    --snapshot-arn sampleResourceName

For Windows:

aws docdb-elastic get-cluster-snapshot ^
    --snapshot-arn sampleResourceName

To view information about a specific elastic cluster snapshot using the Amazon CLI, use the get-cluster-snapshot operation with the following parameters:

  • --snapshot-arn—Required. The ARN identifier of the snapshot for which you want information.

In the following example, replace each user input placeholder with your own information.

For Linux, macOS, or Unix:

aws docdb-elastic get-cluster-snapshot \
    --snapshot-arn sampleResourceName

For Windows:

aws docdb-elastic get-cluster-snapshot ^
    --snapshot-arn sampleResourceName

To view information about all elastic cluster snapshots using the Amazon CLI, use the list-cluster-snapshots operation with the following parameters:

  • --snapshot-type—Optional. The type of cluster snapshots to be returned. You can specify one of the following values:

    • automated - Return all cluster snapshots that Amazon DocumentDB has automatically created for your Amazon account.

    • manual - Return all cluster snapshots that you have manually created for your Amazon account.

    • shared - Return all manual cluster snapshots that have been shared to your Amazon account.

    • public - Return all cluster snapshots that have been marked as public.

  • --next-token—Optional. An optional pagination token provided by a previous request. If this parameter is specified, the response includes only records beyond the this token, up to the value specified by max-results.

  • --max-results—Optional. The maximum number of results to include in the response. If more results exist than the specified max-results value, a pagination token (next-token) is included in the response so that the remaining results can be retrieved.

    • Default: 100

    • Minimum 20, maximum 100

In the following example, replace each user input placeholder with your own information.

For Linux, macOS, or Unix:

aws docdb-elastic list-cluster-snapshots \
    --snapshot-type  value \

Restoring an elastic cluster from a snapshot

In this section we explain how to restore an elastic cluster from a snapshot, using either the Amazon Web Services Management Console or Amazon CLI with the following instructions.

Using the Amazon Web Services Management Console

To restore an elastic cluster from a snapshot using the Amazon Web Services Management Console:

  1. Sign into the Amazon Web Services Management Console and open the Amazon DocumentDB console.

  2. In the navigation pane, choose Snapshots.

    Tip

    If you don't see the navigation pane on the left side of your screen, choose the menu icon in the upper-left corner of the navigation pane.

  3. Choose the button to the left of the snapshot, that you want to use to restore a cluster, in the Snapshot identifier column.

  4. Choose Actions, then Restore.

    Diagram: elastic cluster restore from snapshot

  5. On the Restore snapshot page, enter a name for the new cluster in the Cluster identifier field.

    Note

    For any manual snapshot restoration, you must create a new cluster.

  6. In the Virtual Private Cloud (VPC) field, choose a VPC from the drop-down list.

  7. For Subnets and VPC security groups, you can use the defaults or select three subnets of your choice and upto three VPC security groups (minimum one).

  8. If you are satisfied with the cluster configuration, choose Restore cluster and wait while your cluster is restored.

Using the Amazon CLI

To restore an elastic cluster from a snapshot using the Amazon CLI, use the restore-cluster-from-snapshot operation with the following parameters:

  • --cluster-name—Required. The current name of the elastic cluster as entered during creation or last modified.

  • --snapshot-arn—Required. The ARN identifier of the snapshot being used to restore the cluster.

  • --vpc-security-group-ids—Optional. One or more Amazon EC2 and Amazon Virtual Private Cloud (VPC) security groups to associate with the cluster.

  • --kms-key-id—Optional. Configure the KMS key identifier for an encrypted cluster.

    The KMS key identifier is the Amazon Resource Name (ARN) for the Amazon KMS encryption key. If you are creating a cluster using the same Amazon Web Services account that owns the KMS encryption key that is used to encrypt the new cluster, you can use the KMS key alias instead of the ARN for the KMS encryption key.

    If an encryption key is not specified in KmsKeyId and if the StorageEncrypted parameter is true, Amazon DocumentDB uses your default encryption key.

  • --subnet-ids—Optional. Network subnet Ids.

In the following example, replace each user input placeholder with your own information..

For Linux, macOS, or Unix:

aws docdb-elastic restore-cluster-from-snapshot \
     --cluster-name elastic-sample-cluster \
     --snapshot-arn sampleResourceName \
     --vpc-security-group-ids value ec-65f40350 \
     --kms-key-id arn:aws:docdb-elastic:us-east-1:477568257630:cluster/b9f1d489-6c3e-4764-bb42-da62ceb7bda2 \
     --subnet-ids subnet-9253c6a3, subnet-9f1b5af9

For Windows:

aws docdb-elastic restore-cluster-from-snapshot ^
     --cluster-name elastic-sample-cluster ^
     --snapshot-arn sampleResourceName ^
     --vpc-security-group-ids value ec-65f40350 ^
     --kms-key-id arn:aws-cn:docdb-elastic:us-east-1:477568257630:cluster/b9f1d489-6c3e-4764-bb42-da62ceb7bda2 ^
     --subnet-ids subnet-9253c6a3, subnet-9f1b5af9
