  • data archiving

    Data archiving migrates infrequently used data to low-cost, high-capacity archive storage for long-term retention.

  • data backup software

    Backup software makes a duplicate copy of data to protect it and enable recovery if the data is lost or corrupted due to equipment failure or some other catastrophic event.

  • data deduplication hardware

    Data deduplication hardware is a storage product that eliminates redundant copies of data and retains one instance to be stored. Although these products are sold as appliances or disk libraries, they include software that performs the deduplication.

  • data deduplication ratio

    To calculate the deduplication ratio, divide the capacity of backed up data before dupliates are removed by the actual capacity used once the backup is complete.

  • data protection

    Data protection is the process of safeguarding important information from corruption, compromise or loss.

  • 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.

  • data restore

    Data restore is the process of copying backup data from secondary storage and restoring it to its original location or a new location.

  • data retention policy

    A data retention policy dictates the types of data to be retained and the duration for which that data must be stored in accordance with operational or regulatory requirements.

  • deduplication software

    Dedupe software eliminates unnecessary copies of data by redirecting new iterations of the data back to the original.

  • Dell EMC Avamar

    Dell EMC Avamar is a hardware and software data backup product.

  • differential backup

    A differential backup is a type of backup that copies all the data that has changed since the last full backup.

  • DLT (digital linear tape)

    Before the popular Linear Tape-Open Consortium came into existence, Quantum had its proprietary digital linear tape (DLT) format. Learn more about DLT technology here.
