Disabling Deduplication Database (DDB) Activity

Disable DDB activity on the production CommServe host.

Before You Begin

Login to CommCell Console as user with CommCell level Administrative Management capability.

About This Task

When you restore the CommServe database using a disaster recovery backup, the database restores to an older point-in-time. If Deduplication is enabled for any storage policy on the production CommServe, the Deduplication database (DDB) and CommServe database may not be in-sync. To avoid the inconsistency between DDB and CommServe database, disable DDB activity on the production CommServe before performing the disaster recovery backup.

If you do not disable DDB activity before performing the disaster recovery backup, you must resynchronize the Deduplication database when you move CommCell operations back to the production CommServe host.
