Problem
"A communications failure has occurred" (a000fe30 HEX or e000fe30 HEX) is reported during a failed backup job of an Exchange 2000 or Exchange 2003 Server's File System

Final Error Code: a000fe30 HEX (0xa000fe30 HEX) or e000fe30 HEX (0xe000fe30 HEX)
Final Error Description: "A communications failure has occurred."
Final Error Category: Server Errors
Error Text In Job Log:
Exchange Backups
The error "A communication failure has occurred" may occur as the final error description, followed by the error message: "The connection to target system has been lost. Backup set canceled" when backing up the M: drive on a Microsoft Exchange 2000/2003 server. (M: is the default drive letter used by Exchange.)
In Backup Exec (tm) for Windows Servers, each remote server's selections are made to look like the selections are local. Because of this, all drives that are present on the system are enumerated and thus can be selected to be backed up.
Microsoft Exchange 2000/2003 uses the Installable File System (IFS). This technology lays out mailboxes, mail messages, and public stores as files and folders, which show up as drive M:. With this, third-party applications like Microsoft Word and Internet Explorer can use file system application program interface (API) calls to request data, and interact with Microsoft Exchange 2000/2003.
This drive should not be selected under any circumstance, as backing up the data inside this drive can corrupt the Microsoft Exchange Information Store.
To resolve the error, modify the backup job from the Backup Set tab, and deselect the M: drive on all Exchange 2000/2003 servers for the environment (Figure 1).
