  • DDB physical pruning is increasing costs at AWS S3 Glacier library
    Posted: 05-28-2020, 10:48 AM

    Hi!

    I have an issue related to AWS and its S3 Glacier library. DDB pruning is making a big amount of requests every day to this library. Due to the data is not accessible, the DDB pruning process has no sense. Furthermore, that amount of requests to a Glacier library are increasing the monthly cost. To stop it, I decided to unckeck "physical pruning" at the Global Deduplication Policy. I would like that to occurs every 3 months. Does anybody know how to do it?

    Thanks in advanced!

    Please refer this planning document section for Glacier / Archive Cloud storage.  peridcially  Seal the DDB and disable Micro pruning .

    Deduplication Support

    Supported.

    Supported.

    Ensure that the following options are configured on these storage classes:

    • For deduplicated data, make sure to seal the DDB every 6 months, to make sure that the data is periodically pruned. This can be done by setting the value of Create new DDB every [] days option to 180 in the Storage Policy Copy Properties dialog box.

      In addition, as a DDB reconstruction will require all the data to be recalled, it will be very expensive. Hence, choose the Seal and Start new DDB automatically on detection of inconsistency option.

    • Micro-pruning is not supported. Hence, ensure that micro-pruning is disabled. For more information on disabling micro-pruning, see Configuring Micro Pruning.
