The differences between backup and archiving are not stressed here to discredit either approach, but rather to emphasise the importance of both.
This is why Protected DLM is fundamentally different to both traditional HSM utilities and data classification products. Protected DLM integrates data protection, business continuance, and disaster recovery strategies into the long-term retention and management of data as its lifecycle requirements cause it to be copied into and subsequently repositioned entirely to a secondary storage archive. It does this by allowing archives to be defined as multiple copies on multiple media types and it uses a distributed architecture to allow these copies to be written and managed at different network locations. Protected DLM represents the full integration of archiving with other vital storage management processes into a single enterprise-wide facility for ensuring that data is available for both operational and disaster recovery, that it is protected and compliantly retained for suitable periods, and that the most cost effective storage technology can be leveraged to minimise storage and storage management costs.
