# Accelerating Backups to Cloud Storage Libraries

Storage Accelerator can be used on clients to directly send the backup data to a configured cloud storage library. (Without the Storage Accelerator, backups send the client data to the MediaAgent first, and then the MediaAgent stores the data in the cloud storage library.) Storage Accelerator has the following advantages:

- Speeds up backup and restore process by directly backing up and restoring from the cloud storage library and avoiding additional network transmission.

- Reduces the load on the cloud MediaAgent by eliminating the need for processing backup data. (Pruning, Data Verification, and defrag operations would continue to be processed by the destination MediaAgent.)

Note

Support:

- Storage Accelerator can be installed on Windows (x64, ARM64), Linux (x64, ARM64, PPC64), and Darwin x64 Unix clients. (All agents supported on Windows and Linux clients are supported.) However, you can back up data directly to the cloud on all the platforms that support MediaAgent.

- Storage Accelerator is not supported on 32-bit operating systems.

- Storage Accelerator is not supported for Edge Endpoint offline backups.

- To enable automatic installation of the Storage Accelerator package, use the Auto Push Install Storage Accelerator Package additional setting. If the Storage Accelerator package is not installed on a client, the first job schedules the package for installation 4 hours later. Once the package is installed, any subsequent resumed job automatically uses the Storage Accelerator.

## Before You Begin

- Ensure that the client has network connectivity to the cloud server. The client must be able to reach the service host endpoint, when there is a firewall.

- Optionally, create a secondary cloud storage credential for the Storage Accelerator in the mount path. For more information, see Adding a Secondary Cloud Storage Credential for Storage Accelerator.

## Procedure

1. Enable the Storage Accelerator feature at the CommCell level. Set the value for the Config parameter to enable the storage accelerator feature configuration parameter to 1 in the Media Management Configuration.

2. Configure a cloud storage using an appropriate MediaAgent. For instructions, see Configuring Cloud Storage.

3. Create a backup plan and associate the subclients with the copy in the plan. For instructions, see Creating a Backup Plan and Associating CommCell Entities With a Copy.

4. Run a backup from the subclient.

## Result

- View the backup job information. For instructions, see Viewing Jobs.

- When the client computer cannot connect to the cloud storage library, the client computer sends backup data to the MediaAgent, and then the MediaAgent stores the data in the library.

## Additional Information

- Accelerated backups may not work in the following cases:

  - When the Client is behind firewall and hence unable to connect to the cloud.

  - The MediaAgents attached to the library use a credential that works only from that specific MediaAgent. For example, IAM Role.

- If necessary you can disable the Storage Accelerator on a client. For more information, see Enabling or Disabling Storage Accelerator.

- Maximum read, write throughputs to cloud storage can be throttled during certain periods, like the peak business hours. For more information, see Throttling Throughput to Cloud Storage.

- Cloud Test tool is included in the Storage Accelerator package, and will be available on computers where the storage accelerator is installed. For more information, see Tools - Cloud Test Tool.
