Operational efficiency is the ability to store and manage data that consumes the least amount of space with little to no impact on performance; resulting in a lower total operational cost. Efficiency addresses the real-world demands of managing costs, reducing complexity and limiting risk. The efficiency of an empty enterprise level system is commonly in the 40–70% range, depending on what combination of RAID, mirroring and other data protection technologies are deployed, and may be even lower for highly redundant remotely mirrored systems. As data is stored on the system, technologies such as de-duplication and compression may store data at a greater than 1-to-1 data size-to-space consumed ratio, and efficiency rises, often to over 100% for primary data, and thousands of per cent for backup data.
Snapshot technology known formally as delta snapshot technology gives the ability to use the same dataset multiple times for multiple reasons, while storing only the changes between each dataset. Dodid integrates their snapshot capabilities at the operating system and/or application level, enabling access to the data the snapshots are holding at the system and/or application management layers. Data de-duplication technology can be used to very efficiently track and remove duplicate blocks of data inside a storage unit. There are a multitude of implementations, each with their separate advantages and disadvantages. De-duplication is most efficient at the shared storage layer, thin provisioning technology is a technique employed to prevent under-utilization by sharing the allocated, but not yet utilized capacity where every account has a large amount of allocated capacity. Because most users only use a fraction of the allocated capacity, this free space is shared among all users. Actively increasing storage efficiency using these techniques enables time used for both backup and restore can be minimized. This can greatly reduce cost, and reduce hours of downtime to seconds of downtime.
