Archiving is a strategy employed with the management of long-term retention of historical data.
In IT, this is the long-term retention and expiration of unstructured data (such as email or general file data) for compliance and governance, and hence can either point to disk, tape media or to the cloud as the archive target. In a number of instances, it has also been used to reduce the backup window and counter data growth by reclaiming space on expensive Tier 1 production storage.
Single instancing or deduplication is also included with most archive products to eliminate redundant data growth on the archive target. User-determined policies can automate the movement of data that meets a user's stipulated requirements to a tier defined as appropriate by the user.
Information Lifecycle Management (ILM) and Hierarchical Storage Management (HSM) are not new inventions. However, these terms are generically used today by vendors to generate more hype around archiving products. Both ILM and HSM play a critical part in the architecture of tiered storage designs. They are each different and if not used correctly can impact performance, end-user experience and the cost of tiered storage design.
Servnet design archiving solutions based on understanding the customer environment and customer requirements. We identify possible side effects and implications during the design phase to avoid challenges in the long run. There are many archiving vendors who offer choices of varying degrees, but our ability to architect vendor agnostic designs ensures that we build solutions that meet specific customer requirements.
