Recovering Exchange Databases

Recovering Exchange Databases

When your Exchange data becomes damaged or is lost in a disaster, you must recover it from backup. There are several cases in which restoring from backup may be necessary, including:

· Corruption of one or more databases in a storage group In this case, the native single-database restore functionality of Exchange can usually be used to restore the damaged databases without interrupting access to other databases on the same server.

· Hardware failure that causes loss of access to transaction logs or databases In this case, you may have to recover all storage groups, including their associated logs and database files.

· Failure or damage to a mailbox or public folder server that requires the server to be rebuilt In this case, disaster recovery frequently requires rebuilding the underlying server and its operating system.
