Cloud Tier is a native feature of DDOS 6.0 (or later) for moving data from the Active Tier to low-cost, high-capacity object storage in the public, private, or hybrid cloud for long-term retention. Cloud Tier is best suited for long-term storage of infrequently accessed data that is being held for compliance, regulatory, and governance reasons. The ideal data for Cloud Tier is data that is past its normal recovery window.
Cloud Tier is managed using a single protection system namespace. There is no separate cloud gateway or virtual appliance required. Data movement is supported by the native policy management framework. Conceptually, the cloud storage is treated as an additional storage tier (Cloud Tier) attached to the system, and data is moved between tiers as needed. File system metadata associated with the data stored in the cloud is maintained in local storage and mirrored to the cloud. The metadata that resides in local storage facilitates operations such as deduplication, cleaning, Fast Copy, and replication. This local storage is divided into self-contained buckets, called cloud units, for ease of manageability.
Note:
— To configure Cloud Tier, add the license and enclosures, set a system passphrase, and create a file system with support for data movement to the cloud. For Cloud Tier, the cloud capacity license is required.
— To license Cloud Tier, see the applicable DDOS Release Notes for the most up-to-date information about product features, software updates, software compatibility guides, and information about protection products, licensing, and service.
— For information about Cloud Tier requirements, configuring Cloud Tier devices, and Cloud Tier data movement schedules, see the DDOS Administration Guide.
The Commvault integration with the Cloud Tier provides a data protection administrator with the ability to perform the following functions:
Commvault supports multiple cloud services. For information, see the Cloud Tier with Commvault compatibility matrix.
