Cloud Storage - Overview
Cloud Storage enables you to configure and use online storage devices — cloud storage devices — as storage targets. Cloud Storage reduces the need to maintain hardware resources such as tape or disk storage devices at onsite locations. It also provides the ability to easily increase your storage capacity as and when it is required. Cloud Storage provides centralized data access, better failover capabilities and reduces the day-to-day storage administration tasks.
As the data gets transferred over the network, protecting the integrity of data is an important aspect of any cloud storage implementation. Cloud Storage protects the integrity of the data using the following features:
- By default, data is transferred through secured channels using HTTPS protocol.
HTTPS can be overridden to use HTTP during configuration , if it is required. For example , on premise object storage that support S3, SWIFT protocols which connects using HTTP.
- Data encryption feature further encrypts the data providing data protection during network transfer as well as storage.
The deduplication feature enables you to reduce cloud storage space usage and use network bandwidth efficiently. Deduplication identifies and eliminates redundant data in the backup, reducing not only the volume of data stored in cloud but also the bandwidth required for data transfer.
Purchase your cloud storage account and acquire the access credentials. A list of the supported cloud storage vendors and access to their website containing account purchase information can be accessed from Cloud Storage - Support. After purchase of the Cloud Storage account, the cloud storage can be configured in two ways:
Cloud as a Direct Storage Target
In the direct cloud setup, the client computers are connected to the cloud library through the MediaAgent computer. During a data protection operation, the MediaAgent sends the client data directly to the cloud storage.
To setup Cloud as a direct storage target, see Cloud Storage as direct cloud setup.
Cloud Using Proxy
In the Proxy cloud setup, the MediaAgent, which is connected to the cloud library through a proxy host. During a data protection operation, the MediaAgent sends the client data to the cloud storage through a proxy host.
To setup Cloud using Proxy, see Setup Cloud Using Proxy.
