Hello,
From the event id (7034) it seems that this error might be produced in case you are running a job type of "Archive - delete files after successful copy backup" with three or more partitions selected , then Backup Exec Remote Agent for Windows Servers service terminates.
If this is the case then please refer the following technote:
