Many organizations are struggling to meet escalating backup and recovery service-level requirements.
Rapid growth of information in the production environment is the root cause. The prime concern, and the real driver for most of the challenges in this space, is the continued fast growth of information in the enterprise.
Most Industry Analysts believe the growth rate is approximately 60% per year. As IT budgets are basically flat, this immediately suggests that businesses need to start thinking differently about how they deal with enterprise information growth. Not only is new information entering the enterprise more quickly, but more of it is accumulating over time in response to corporate policies and governmental regulations around data retention. This has multiplied the amount of information IT needs to care for in the environment.
The current methods that many rely on for backup and data retention simply cannot keep up. Backup-infrastructure size and growth is tied directly to the size and growth of the production environment. As production capacities grow, so does the backup.
We have also found that many customers are relying on periodic backup images as their solution for long-term data retention. This causes a management headache for information retrievals and further swells the backup environment.
