Note that when backing up the active copy, the exchange server was getting loaded and the end users were nno longer able to send and receive emails during the backup. So i changed the backup job to take a backup of the passive copy instead. The issue got solved and the backups became faster. However the excchange jobof the passive copy is now failing with the following error:
Final error: 0xe000037b - Using the job settings, Backup Exec attempted to back up the passive copy of the Exchange database. However, the passive copy was not available after the Microsoft Volume Shadow Copy Service (VSS) snapshot was performed. Try to run the job again. Final error category: Resource Errors For additional information regarding this error refer to link V-79-57344-891

I enabled the AOFO and enabledthe VSS service and microsoft shadow copy provider and set them to manual but the job failed as well. Then i disabled the AOFO but the job failed as well. I tried rebooting the server but the job failed as well. What could be the reason for the failures?
How can I solve the issue?
Check the VSS Writers on your exchange server (Open CMD Prompt window as an Administrator and type vssadmin list writers) and verify if they are stable with no errors.
