  • Hi All,

    Could someone explain the criteria DPM considers on using the tapes for protection groups configured for short/long term on tapes.

    Is it based on.

    1.Protection Groups Name

    2.The Configured Data retention 

    3.Data Selection on Protection Groups

    4.Application Type selected.

    Appreciate a detailed explanation or a link that provides more info.

    Thanks in advance.

  • Co-Locating Data on Tape
    System Center Data Protection Manager (DPM) allows you to co-locate protection groups on a tape. Using this feature, you can group recovery points of multiple protection groups on a single tape. This optimizes the tape usage in case you have many small protection groups.


    The following restrictions apply to using data co-location in DPM:

    • You cannot apply co-location selectively. If enabled, it applies to all protection groups.

    • Only protection groups with the same retention period can be co-located on the same tape.

    • Encrypted and non-encrypted datasets cannot be co-located on the same tape.

    • Datasets from short-term backup to tape and long-term backup to tape cannot be collocated.
