Preventing Exchange Server downtime

Preventing Exchange Server downtime
Adesh Rampat

For many organizations Exchange services are an essential aspect of the business. If the Exchange server shuts down the business operations can be severely affected. The following list provides ways in which to reduce downtime in the event of an Exchange Server failure.

  • Have more than one Exchange server to allow for replication. If your backup Exchange server is not the same configuration as the primary Exchange server then you can implement a Failover system which provides data replication continuously so that in the event of a failure control is passed in its entirety to the secondary Exchange server.

  • Make sure that anti-virus services are updated on both Exchange servers.

  • Do not make the Exchange server the Primary Domain Controller.

  • If the Exchange Server is configured as a member server make sure there is at least one Backup Domain Controller in the domain.

  • Check event logs daily.

  • Have the transaction logs on separate disks.

  • Disable circular logging.

  • Take full online backups every day.

  • Run RDISK /s on the Exchange server regularly.

  • Keep all backups in a fireproof vault if possible.

  • Have the Information Store database on disks set for RAID 5.

  • Check disk-space usage on a regular basis.

  • Connect your Exchange servers to UPS systems to prevent sudden power loss.
