We have a server that backups locally to an external drive and to Azure. This has been working as expected for several months, but after a job was stopped before completion due to an emergency shutdown for a power outage Azure backups do not complete and give the error message "Job failed because another backup job was in progress." Windows Server backups to external disk still complete as expected, and there do not appear to be any jobs in progress for either Windows Server Backup or Azure Backup.
Restarting the Volume Shadow Copy does not have any affect - we still get the same error message.
Can you please suggest what can be done to clear out this error and try the job again?
