Hi. Every time after a backup runs (using Backup Exec 11d) we get multiple of the following event IDs logged to the application log on our Exchange 2007 mailbox server. We are running a CCR cluster on 2 Windows 2003 x64 Enterprise machines. The CAS & Hub are on a separate 2003 x64 machine. We also have a mailbox/cas/hub server offsite and we use SCR to replicate the data to it from the CCR cluster.Event Type: WarningEvent Source: ESE BACKUPEvent Category: General Event ID: 915Date: 1/23/2008Time: 1:31:07 AMUser: N/AComputer: EX02Description:Information Store (4108) There were 1 log file(s) not found in the log range (E:\MailLogs\FourthDBLogs\E01000007CC.log - E:\MailLogs\FourthDBLogs\E01000007CC.log) that we attempted to truncate. For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.I haven't been able to find any information on this on microsoft.com, eventid.net and googling hasn't helped either. I thougt I'd post here to see if someone else might have seen this before. The backup logs look good, we are getting successful backups and the logs are truncating as expected (space is freeing up on the logs drive).Thanks in advance for any information you guys might be able to share on this.Lenny

I have this exact configuration and am receiving the same errors. Any resolution? I'm running Exch 2007 SP1 as well. Thanks!
