Add storage groups and databases

When adding a new storage group to a protected Microsoft Exchange server, you must add it to a protection group manually. When adding a new database to the storage group, a full backup is required, which can be accomplished by an express full backup or a consistency check. Incremental backups will fail until a full backup is completed.
In Exchange Server 2010, databases are grouped under database availability group (DAG). If a database in a DAG on which express full backup is configured goes down temporarily and returns back then you do not have to perform any action.
However if it goes down for a longer duration, then the backups will fail and Exchange Server will be unable to truncate log files for that database. Also the respective DAG node on which the database exists may run out of disk space.
To resolve this issue, you must manually reconfigure an express full backup on another copy of the database so that log truncation happens for that database.
