Data Storage Definition

  • Frequently Misused Term (some initiatives are scoped to what should be considered “Information Storage”)
  • Sub-Discipline of “Data Management”
  • Information Types: Structured

Data storage can refer to any electronic storage of structured data. The term is often used in reference to archival or tiered storage, or data that is set aside for non-critical purposes. Data storage techniques often focus on cost reduction and may be related to backup activities. Data Storage is a frequently misused term and should be replaced with “Information Storage” where it matches the reality of the practice.

Data Storage Key Points

  1. Data storage is focused on structured data.
  2. Data storage relates to optimization and availability of resources.
  3. Data storage is often established in conjunction with data backup capabilities.
  4. Data storage is often the label utilized for readily accessible data, whereas data backup and tiered storage are terms for less frequently utilized data.
  5. Tiered storage is often leveraged as a strategy for data storage where data can be categorized as online, nearline, and offline.
  6. Online data is readily accessible and available.
  7. Nearline data is accessible but may take slightly longer to retrieve or have longer load times than online data.
  8. Offline data is often inaccessible to most, with availability to a select few but may take some time.
  9. Data categorization of online, nearline, and offline should be established and tiered based on organizational requirements.

Data Storage Overview

Data Storage Tiering

Data Storage is the tiered management of stored data to reduce cost and maximize efficiency. While often partnering with Backup capabilities and practices, Data Storage should ensure that data is available in as timely a manner matching its’ value to the organization. Some data may be stored off-site depending on organizational requirements.

Information Professionals executing on Data Storage initiatives should ensure they are taking guidance from the business, especially in making determinations of the value of particular repositories of data. Data access is often used as a substitute for data importance. However, this is an incorrect assumption. How quickly the data needs to be accessed is not directly proportional to how often the data is accessed. This is a common mistake in Data Storage efforts.

Some data may have a high business value, but not have an immediate access requirement. Conversely, data with a lower value may need immediate access. This is what makes Data Storage efforts complex and what differentiates it from Backup and Business Continuity efforts. Although they are different practices, they should definitely confer and discuss their assessment findings with one another in regards to data importance and access requirements.
