Securely Backing Up Syracuse University
9/1/2004
The capabilities of the university’s new backup and recovery system were recently tested during a domain controller upgrade, one Friday afternoon, when the server suddenly became inoperable. Syracuse’s fallback plan simply takes a snapshot image of the operating system volume right before applying a patch. If the patch causes problems, the server can be rolled back to the exact state it was in before. Within 15 to 30 minutes, servers can be up and running.
Moving forward, Syracuse is building an off-site location for disaster recovery to allow the system to be more encompassing. It also plans to look at how to further integrate security and storage/backup systems to improve response times during virus outbreaks. The sooner a malicious threat can be identified by security technologies, the better the chance of making clean backups of mission-critical servers and patching the vulnerability without being exploited by the threat.
