Enabling Amazon S3 Glacier Faster Restores

To enable Faster Restores for S3 Glacier, verify that your environment meets the prerequisites and enable faster restores in Commvault. Then you can begin running faster restores.

Prerequisites

Before you configure faster restores, verify that your Commvault environment meets the prerequisites.

Prerequisites for Amazon S3 Faster Restores
  • You must have a Commvault cloud storage location (an Amazon S3 bucket) configured with one of the following storage classes (with or without deduplication enabled):

    • Amazon S3 Glacier Flexible Retrieval

    • Amazon S3 Glacier Deep Archive

    • Amazon S3 Intelligent-Tiering with Archive Access Tier

    • Amazon S3 Intelligent-Tiering with Deep Archive Access Tier

    • Amazon S3 Intelligent-Tiering with Archive Access and Deep Archive Access Tier

    Commvault recommends that when S3 Glacier Flexible Retrieval or S3 Glacier Deep Archive storage class are used, the Use combined storage toggle key is enabled on the Cloud Storage location. (This setting is enabled by default when creating the Cloud storage in Commvault Command Center).

  • You must have a Server plan for protection and decommissioning of workloads.

  • You must have a workload configured and backed up to the configured cloud storage location.

    For example, you might have an Amazon EC2 VM group. For this VM group, you can use resource tagging rules, such as AWS Resource tags or Kubernetes Label selectors, to automatically discover compute and containerized workloads to protect at backup runtime. This approach simplifies cloud operations, and auto-adjusts as workloads are deployed and terminated.

You can also use the Commvault Command Line (CLI) or REST API to complete the preceding steps.

Enable Faster Restores

Set the following mandatory FeatureGates (called entity settings in the Command Center) to enable faster restores:

Name

Entity

Category

Type

Value

EnableS3BatchOperationsRestore

MediaAgent

MediaAgent

Boolean

True

Important

You must also configure the S3BatchOperationsRoleArn additional setting to use this feature.

S3BatchOperationsRoleArn

MediaAgent

MediaAgent

String

The name of the AWS IAM role that you created for faster restores

For example, arn:aws:iam:012345678910:role/CommvaultBackupAndRecoveryBatchRestores

Important

Do not specify the entire ARN. Specify only the role name.

Optionally, customize faster restores behaviour with the following optional FeatureGates (called entity settings):

Name

Entity

Category

Type

Value

nCloudChunkRecallSleepIntervalMins

MediaAgent

CommServe

Integer

Amount of time in minutes before Commvault starts polling for restore completion.

Default value is 20 minutes (with Batch Operations) or 540 minutes (without Batch Operations).

AutoCloudRecallExpireDays

CommServe

CommServDB.GxGlobalIParam

Integer

Set the number of days after which data recalled from archive storage class for cloud storage will expire.

Set to 1 for restores from S3 Glacier Flexible Retrieval.

Set to 1 (or greater) for restores from S3 Glacier Deep Archive.

Default: 7
