Storage Acceleration (also known as Client-Direct Mode) can be set up on clients to directly send the back up data to a configured Data Domain Boost Client storage library. (Without Storage Acceleration, clients send the back up data to the MediaAgent first, and then the MediaAgent writes the data into the Data Domain Boost Client storage library.)
Storage Acceleration has the following advantages:
- Speeds up back up and restore process by directly backing up and restoring from the Data Domain
- Boost Client library and avoiding additional network transmission.
- Clients would have the Dell DD Boost SDK module on it which allows it to perform client-side deduplication and compression of the data before sending to the Data Domain device. Reduces the load on the MediaAgent by eliminating the need for processing back up data. (Metadata and Indexing operations would continue to be processed by the MediaAgent)
The data flow diagram for the storage acceleration feature is given below:
Normally the Storage Accelerator package is used for this use case, but for Dell DD Boost library types, the MediaAgent package is installed instead. This is due to the size of the package required by the Dell DD Boost SDK and dependencies. In this configuration the MediaAgent package will function similar to the Storage Accelerator package, and the client does not need any additional resources. It will not be carrying out any of the typical MediaAgent functions other than direct data movement to the Data Domain Boost library via the included Boost SDK.
- The MediaAgent package can be installed on 64-bit Windows and Linux clients. (All the agents supported on Windows and Linux clients is supported.) However, you can back up data directly to the cloud on all the platforms that support MediaAgent.
- The MediaAgent package is not supported on 32-bit operating systems.
- The MediaAgent package is not supported for Edge Endpoint offline back ups.
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.
- Configure a Data Domain Boost Client Storage library using an appropriate MediaAgent as described in Data Domain Boost Client.
- Create a Storage Policy using the MediaAgent or the Data Domain Boost Client Storage library as the data path in the storage library. For more information, see Creating Storage Policy.
- Install the MediaAgent package MediaAgent Package on all clients that you want to back up directly to the Data Domain.
- Associate the Storage Policy with the sub-client used to back up data from the client.
- Run a back up from the subclient.
The software sends the back up data directly to the Data Domain Boost Client storage library. The name of the client appears as the MediaAgent in the Streams tab of the Job Details dialog box of the running back up job.
For instructions about viewing the job details of a running back up job, see View Job Details.
For information about the Streams tab, see Backup/Information Management Job Details (Streams) section in Job Controller Online Help.
Accelerated back ups may not work when the client is behind firewall and hence unable to connect to the Data Domain Boost Client storage library.
If necessary, you can disable the Storage Accelerator mode on a client which will cause it to send back up data to the MediaAgent, and then the MediaAgent will write the data to the library. For more information, see Enabling or Disabling Storage Accelerator.
