i already read that. That does nto describe what to do if the DD database gets corrupted.

MSDP should not be your only backup. You should always have it duplicated somewhere else. Other MSDP or tape. Your biggest risk is not dedupe corruption as several protections is built into NBU 7.6. What if your hardware (disk) fails?

[Nicolai · Accepted solution]

Both MSDP (Symantec) and Data Domain (EMC) has in the design gone a lot to secure the integrity of the dedupe database.  In NBU 7.6, the index of the MSDP deduplication database has become self healing, but that does not protect you from corruption of deduplication database containers. 

duplicate data across MSDP pool to secure data.

Hi BTLOMS,

You can also read Symantec NetBackup deduplication Guide (page 58), Symantec recommends methods in protecting the deduplicated data. Below is the link
