Thats expected behavior, now you dont need to select CAR/CDR
CSCsj17740 CDR_CAR component shown as different feature on DRS
Symptom:
CDR_CAR is still listed or registered as a standalone DRS component, although its functionality has been bundled with CCMDB DRS component.
Conditions:
Go to DRS config page.
Workaround:
Simply don't use CDR_CAR to do backup/restore, and use CCMDB instead. It will backup/restore all CCMDB related items and CDR_CAR related items together (i.e. CCM db, CAR db, CAR pre-generated reports, and unprocessed CDR/CMR flat files, etc).
