Error in trying to backup Exchange server

Some extra details - Base and Hyper V Exch server are both 2008 R2

Used the Administrator account for all permissions

Tried 2 different backup areas on local disk

Tried disabling the firewall to no effect

I installed the Windows Agent on the Exchange Server. This removed the ability to backup the Exchange server, as it was asking to backup drives etc.

I then uninstalled it again, leaving only the Agent for exchange.

When trying the backup, now it completes, but it ends with errors - the errors seem to happen only when the validations starts - as the validation completes in only about 10 seconds.

The management console still reports as the backup having never been successfully completed. I do get the right size of file in the backup location for the amount of data being backed up.

The errors are the following (Note that there is an Administrator email account.

I uninstalled ABR/Exchange from the exchange server. I re installed it with default options + a local console.

I can perform a backup from within the Exchange Server (ie locally - and the backup directs to a network drive).

If I try to perform the backup from the base server (the one with the management), the backup occurs without errors, but nothing is backed up (the whole process completes in 2 seconds). When I try to peek into what is backed up, it only says Disk 1 with no info, whereas from within the Exchange server locally - I see all the databases etc.

I created a schedule within the Exchange Server, and the backups occur from there, but I would prefer to be able to do it from the central location.

Any ideas

It's possible that you select wrong data type while creating centralized plan. There is a switch on a yellow background named 'data to back up' in 'Data to back up' above the tree. If you create centralized backup plan (what you call backup from the base server) is defaults to 'disks/volumes' no matter if there is agent to back up disks on selected machines. When you create local plan, there is no choice and the type is 'exchange' (databases or mailboxes, and fortunately the default is the first) and everything works. When backup plan with 'disks/volumes' type is sent to machine that can't do it, strange things happen.

The problem cause is not Acronis, it is the public folder:

•Perform one of the following actions:

If you are running a 32-bit version of Windows®, navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Messaging Subsystem\CDO.

If you are running a 64-bit version of Windows, navigate to HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows Messaging Subsystem.

•If the CDO registry key does not exist, create a registry key that you name CDO.
•In the CDO registry key, if the DWORD value does not exist, create a DWORD value that you name Ignore No PF.
•Change the DWORD value to 1.
•Click OK.
•Close Registry and restart the server.
