What are your Backup Exec & System Recovery backup schedules ?

If you disable System Recovery temporarily, do the backups complete ?

After the backup job failure, do restart the Symantec SymSnap VSS Provider and Volume Shadow Copy services via services.msc

Hi

Please also check if your maintainence for exchange databases is schedule during backup time window if that is the case please change the database maintainence schedule to run at some different time or else configure backup to run at some different time

Thanks
