Space Reclamation Operation on Air Gap Protect:
Do not perform space reclamation operation on Air Gap Protect on a regular basis. You must consult Commvault Support before you perform a space reclamation operation on Air Gap Protect.
Consider the following options for Air Gap Protect storage:
-
Option 1: Set the Don’t dedupe objects older than x days option based on the following retention on the DDB.
- Retention 0 to 7 days - 90 days
- Retention 8 to 30 days - 120 days
- Retention 31 to 180 days - 180 days
If Extended Retention is configured, split the copy in to two copies to separate extended retention.
Copy 1 with 30 days retention and Copy 2 (selective copy with monthly fulls) with 365 days retention - On copy 1 storage pool, set Don’t dedupe objects older than x days with 60 days. - On copy 2 storage pool, set Don’t dedupe objects older than x days with 365 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 Air Gap Protect.
-
Option 3: If option 2 is not possible to provision MediaAgent, then purchase additional storage capacity to cover the bloat.
