We are going to be moving to Exchange 2010. Basically we will have 14,000 users and will allow users to go up to 4 gig mailboxes. We will have 4 backends distributed between 2 on-site buildings for redundancy (power/network). We will also be deploying a DAG configuration with 2 copies per database. We are talking a ton of storage and the question keeps arising about backups. I've heard with the DAG deployment, a backup system isn't really required because of the database replication, but my mind keeps going back to the possibility of database corruption. Total data to be backed up could be 192 terabytes, so it's a large amount of data. I was wondering what other large shops are using for that type of data. Comments on backup strategies for 2010?
