V-79-57344-3844 - The media server was unable to connect to the Remote Agent on machine ADVENT03.
The media server will use the local agent to try to complete the operation.
WARNING: Media servers cannot completely protect remote Windows-based servers or workstations unless the Backup Exec Remote Agent is installed and running on each remote Windows-based server or workstation to be protected. Data loss can occur if the Remote Agent is not running while backing up remote Windows-based computers.

Changes for Streaming Backups in Exchange 2007 SP1
As part of the Microsoft continuing security initiatives, Microsoft Exchange Server 2007 Service Pack 1 (SP1) introduces a behavior change designed to reduce the attack surface of the system. This change directly affects remote streaming backups.

The release to manufacturing (RTM) version of Exchange Server 2007 has remote streaming backup enabled by default. This default configuration is less secure because it allows anyone in the domain with sufficient backup rights to back up a server that is running Exchange. Moreover, data that is backed up remotely is not encrypted, and the backup is often performed over a public (client-accessible) network.

To adhere to the Microsoft Secure by Default initiative, the remote streaming functionality disabled (server-wide) in Exchange 2007 SP1 is disabled by default. A manual override in the form of the following registry value must be enabled to restore this functionality:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeIS\ParametersSystem

Name: Enable Remote Streaming Backup

Type: DWORD

Value: 0 = default behavior (remote backup disabled); 1 = remote backup enabled

There are two cases where enabling remote streaming backups is required:

Cluster continuous replication (CCR) environments require remote streaming backup for seed operations (for example, when using the Update-StorageGroupCopy cmdlet).

Third-party applications may require remote streaming backup functionality. Check with your application vendor to see if your application requires remote streaming backup capabilities.

Hi.

My name is Fabian, im from Bs. As., Argentina.

I have an Exchange 2007 SP1 Server, and another computer running Symantec Backup Exec V12 (All is up to date).

In the Regedit of the Exchange 2007 Server theres not an DWORD registry called "Enable Remote Streaming Backup", and my Exchange Backups are not working.

I try creating that registry, but it didnt work. Is there a Solution to this?

Thanks!!
