Demand by Mid-Sized Organizations for New Approaches to Storing and Managing Unstructured Data

· Utilization of replication and archiving solutions using disk-based technologies. In order to obtain greater availability and protection of their unstructured data, organizations are replacing tape and optical-based backup systems with SATA disk-based replication and archiving solutions. Many organizations find it important to replicate data to protect their information from various threats and disasters. Replication helps ensure that an organization will be able to access its data from a secondary source in case of data loss or corruption. The purpose of an archive is to store file-based information in a secure and cost-effective manner for the long-term while enabling the retrieval of specific files more quickly and easily than a tape-based or optical-based archive. The Enterprise Strategy Group estimates that the capacity of external disk storage dedicated to archiving will grow from approximately 9,700 petabytes in 2010 to over 106,800 petabytes in 2015, representing a CAGR of 62%.
