Data Backup Resources Definitions

  • D

    dark backup

    A dark backup is one that can be run automatically without manual intervention.

  • data protection management (DPM)

    Data protection management (DPM) is the administration of backup processes to ensure that tasks run on schedule, and that data is securely backed up and recoverable. Good data protection management means having effective processes and methodologies in place to maintain data integrity.

  • data reduction

    Data reduction minimizes the amount of data an organization needs to store, usually by eliminating redundant information. The most common data reduction methods are deduplication and compression.

  • E

    encryption key management

    Encryption key management is the administration of tasks involved with protecting, storing, backing up and organizing encryption keys.

  • G

    global data deduplication

    Global data deduplication is a method of preventing redundant data when backing up data to multiple deduplication devices.

  • I

    inline deduplication

    Inline deduplication is the removal of redundancies from data before or as it is being written to a backup device.

  • L

    LAN-free backup

    LAN-free backup is the process of backing up server data to a centralized storage device rather than moving it across a local-area network (LAN).

  • LTO-5 (Linear Tape-Open 5)

    First released in 2010, LTO-5 is a tape format from the Linear Tape-Open Consortium. Though LTO-6 is available, LTO-5 remains popular among tape users.

  • N

    near-continuous data protection (near CDP)

    Near-continuous data protection, sometimes called near-continuous protection, is a general term for backup and recovery products that take snapshots at set intervals. The term evolved from a need to differentiate products that take snapshots on a pre-determined schedule (every fifteen minutes, for example) from those products that take snapshots each time new data is written (true CDP).

  • P

    post-processing deduplication (PPD)

    Post-processing deduplication (PPD), also known as asynchronous de-duplication, is the analysis and removal of redundant data after a backup is complete and data has been written to storage.

  • R

    remote replication

    Remote replication is the process of copying production data to a device at a remote location for data protection or disaster recovery purposes.

  • removable media

    Removable media is any type of storage device that can be removed from a computer while the system is running. Examples of removable media include CDs, DVDs and Blu-Ray disks, as well as diskettes and USB drives

  • ROBO backup (remote data backup)

    ROBO backup is the process of copying and archiving data created by remote and branch offices (ROBOs) and storing it securely.

  • S

    source deduplication

    Source deduplication is the removal of redundancies from data before transmission to the backup target.

  • T

    tape shoe-shining or back-hitching

    Tape shoe-shining (also known as tape back-hitching) refers to the back and forth motion a tape drive makes when the data stream to the drive is interrupted.
