Backup Gateways

Backup gateways handle important functions and use cases.

You don't need to protect backup gateways, and you can re-create them if they're deleted.

Functions

Backup gateways function as both access nodes and MediaAgents:

• As access nodes, backup gateways connect with, discover, back up, and restore your data source (which the Commvault Cloud control panel cannot access directly by the Commvault Cloud control plane).

• As MediaAgents, backup gateways move data to and from the access nodes to the storage targets. Backup gateways also perform deduplication operations before moving data to storage targets.

Use Cases

The following use cases require a backup gateway.

Protecting On-Premises Data Sources Using a Backup Gateway

If you want to protect on-premises data sources, and you require a local copy of the backup data, you can use a backup gateway. For more information, see System Requirements for On-Premises Backup Gateways.

To create an on-premises backup gateway, use the configuration wizard for the following on-premises workloads:

• File servers

• Hyper-V VMs

• Nutanix AHV VMs

• Oracle databases

• Oracle RAC databases

• SAP HANA databases

• SQL Server databases

• VMware VMs

Protecting Cloud Data Sources Using a Cloud Backup Gateway

If you want to protect cloud data sources that have restricted network access, you can use a cloud backup gateway. For more information, see the following pages:

• System Requirements for AWS Backup Gateways

• System Requirements for OCI Backup Gateways

• System Requirements for Azure Backup Gateways

Use the configuration wizard for the following cloud workloads to create a cloud backup gateway:

• Amazon EC2 instances

• AWS cloud databases

• Azure databases

• Amazon S3

• Azure Blob Storage

• Azure Files

• Azure Data Lake Storage Gen2

• OCI VMs

• OCI databases

• OCI Object Storage
