Created: 08 May 2014 • Updated: 09 May 2014

Hello all Symantec experts,

We use Symantec Backup Exec 2012.

We get the errors of "Backup Exec Job Failed" for the backup job of "backup Exchange Server 2010's data into tapes"

We haven't installed Exchange Management Tool on our Symantec Backup Exec media server.

This "Backup Failed" alert message does not happen every day.

It only show up in a random range of days. The backup job always run properly except some random days.

Please help give some advices on our situation.

Thanks very much !
