what is the retention policy in NetBackup integrating with Data Domain?
Suppose I am using Data Domain as STU in NBU with Data Domain boost. What retention policy should be look like? I may not quite understand it conceptually, but is retention policy applicable if I using Data Domain? I read some documents, and retention policy seem not configured. I don't see any where to define how long I should keep daily, weekly or monthly backup. I must be missing something here.
Please shed some lights on this concept.
