    Consider the following options for MRR storage:

      • Retention 0 to 7 days - 90 days
      • Retention 8 to 30 days - 120 days
      • Retention 31 to 180 days - 180 days

      For more information, see the Deduplication Database Properties - Settings section in Online Help

    • Option 2: If the defragmentation bloat (difference between the estimated media size and the size on disk) is higher than the 30%, then provision extra small and temporary MediaAgent in the same cloud region, and run the space reclamation job.

      Note

      Contact your Commvault Support for the authorization to perform space reclamation operation for MRR.

    • Option 3: If option 2 is not possible to provision MediaAgent, then purchase additional storage capacity to cover the bloat.
