Exchange 2003 Disaster Recovery: Planning and Strategies

Hello! today to learn how to perform a disaster recovery of Exchange Server 2003 or in Exchange 2003 Disaster Recovery . This procedure should be performed when an Exchange server collapses or has a hardware failure which can not continue working. This post I devider in three parts.

Part I: Making a backup or backup of the Exchange database using ntbackup.exe.

Part II: Installing Exchange Server Disaster Recovery mode.

Part III: recover or restore an Exchange database.

NOTE: For the Disaster Recovery mode installation must comply with the versions of Exchange and
Operating System for the Disaster Recovery procedure a success. Tambipén we must respect the structure
storage units, rather if there were three drives C:, D: and E: and C: was
the Exchange installation folder in D: Database (*. edb and *. stm) and E: the logs, should
retained this structure in the new Exchange server.

Part I Backup or Backup the Exchange using Ntbackup.exe BD. I recommend scheduling a task for the backup of the database is done on a schedule of less demand and did not cross with online defragmentation. In Exchange 2003 the default is used to support Shadow Copy the database and there is no need to remove the database.

Steps:

1. Login to ntbackup.exe and make a backup of the Storage Group, which includes the mailbox store and public store. The backup is performed without removing the mailbox database, Windows 2003 makes use of the Shadow Copies allowing the backup is online.
2. remember that we can set up scheduled tasks to perform backups or backup the Storage Groups. Tebemos two options: full backups every day of the week or a day full backup weekly and incremental backups six days.
