Hey xiwen, 

  1. The DDB and the Index are automatically backed up and automatically restored / reconstructed if required. 
  2. If you need immediate Media Agent recoverability, then deploy two - if you lose one the other can carry on.

Better still spread your DR over two sites with a Media Agent at each site and a copy of the data at each site too!.

Please note that the DDB is not needed for restore, just the Index is (for browsing the backup and restoring single files). The Index will be automatically recovered from the backup media when browsing the backup.

Having that said, you just need an “empty” MediaAgent that has access to the backup media (i.e. disk library or tape library) to be able to restore the data.
