A company recently deployed an MS SharePoint farm that consists of three Web Front End (WFE) servers, three application servers and two database servers. Avamar backup software setup and configuration was completed according to EMC best practices and one of the WFE servers was designated as "owner" of the backup.
Federated backups of this farm were running successfully for the past 30 days, but last night's backup of the entire farm failed. Quick investigation with the server team revealed that the main system board failed on the WFE server where the front-end plug-in was installed. This server cannot be repaired fast enough to meet the backup SLA.
What should be done to resume backups as soon as possible?
