Exchange Disaster Recovery Fundamentals – Kind of toolish


Ha recovery options
HA + Recovery Options

  • Dialtone Recover

  • Setup / Bla

  • Legacy Exchange mailbox servers

    • Failover Cluster

  • Exchange 2007 Mailbox role

    • Single Copy Cluster (SCC)

    • Clustered Continuous Replication (CCR)

    • Local Continuous Replication (LCR)

    • Standby Continuous Replication (SCR)

  • Exchange 2010 Mailbox role

    • Database Availability Group (DAG)


Dialtone recovery
Dialtone Recovery

  • Purpose is to give you time to fix or repair a database

  • How to

    • Move the active database and log files to a temp location

    • Mount the databases and say yes when it asks you if you want to create a new database

    • Play all of the dialtone database information into the recovered database

  • Things to note

    • Users get new email but they cannot see old stuff in Outlook at the same time.

    • Users can see new email in OWA, and old email in Outlook at the same time


Setup bla
Setup / Bla

  • 2000 and 2003 setup /disasterrecovery will restore all of the settings from AD to a server

      • IIS metabase on the CAS server

      • UM prompts on the UM server

      • Registry and XML customizations
