- Disk to disk backup
- Long term storage of reference data
The use of data and its frequency of use changes over time. This can be roughly divided into "frequently accessed data" and "infrequently accessed data". Data having a high frequency profile will require to be fetched immediately and should be stored on high-performance storage devices. However, storing infrequently accessed data on high-performance storage devices generates unnecessary cost. To meet the growing demand for cost-effective high-capacity storage, for less frequently accessed data, Fujitsu provides high-capacity, highly-reliability, yet low-cost, Nearline disk drive options in its ETERNUS disk storage systems.
