I have a query . If a storage library has 8 mount paths , all configured from different media agents and shared with each other .
Should we create DDB partition on all 8 media agents or only on 1 media agent ?
What will help to increase performance of backup jobs , DDB is hosted only on 1 media agent or distributed across multiple media agents ? I am thinking that if DDB is hosted only on 1 MA backup job has to look only on 1 MA everytime for duplicate blocks and signatures , if the DDB is distributed wouldn't it make the backup job slower as the backup job will check for duplicate blocks and signatures across multiple configured DDB partitions .
Let me know if my understanding is incorrect ?
