The Data Management TechKNOWvatioN deals with the processes and practices involved with maintaining the integrity of the data in a technically complex environment over the life cycle of the data. This includes both protecting data from loss and managing the data and data storage devices effectively.
The Data Protection TechKNOWvatioN Service is the set of services that protect on-line and off-line data to ensure its availability in the event of loss or future need. On-line data is data stored on high speed or low speed devices as well as data that is logically on-line on lower speed devices. Off-line data is data stored on removable media that is not readily accessible without manual intervention.
The Backup and Restore Element is the service that provides protection of on-line data. Backup and Restore is concerned with periodically copying on-line data to an off-line data storage media. Should the on-line data be lost or corrupted, the goal of Backup and Restore is to bring the data back on-line to the state it was in at the time the last backup was performed.
The Archive Element is a service responsible for the retention of data for extended lengths of time by moving it to off-line storage. Archival is concerned with how data is moved from on-line to permanent off-line storage. Archival implies an intentional act (by the owner of the data) to move data from on-line to off-line, permanent storage.
The Data Migration Element is the service responsible for the retention of data for extended periods of time by moving it to lower speed, longer access storage. Migration is concerned with how data is moved from on-line, high speed storage to logically on-line, lower speed storage media. Migration implies no intentional act (by the owner of the data) to move data, but is accomplished automatically.
The On-line Storage Management TechKNOWvatioN Service is the set of services that manage on-line data and files to ensure availability of on-line data resources to users of a technically complex environment. These services include managing the on-line storage devices as well as the data on these devices.
The File Management Element is the service responsible for managing on-line data. File management is concerned with issues such as the size of files, the replication or duplication of files, and public or shared directories.
The Disk Management Element is the service responsible for managing on-line storage devices. Disk management is concerned with issues such as fault tolerance device management, disk quotas, public or shared disks, and temporary disk space management. Disk management deals with managing disks or areas of disks, knowing what those areas are used for, and how they are being used.
The Data Capacity Planning Element is the service that measures and tracks data capacity usage, and projects the data capacity requirements for a group or organization. Capacity planning is concerned with how data storage is currently being and will be used by the organization.
