I am having trouble completing my backup. I am using ntbackup, which runs on schedule and had been running just fine. But it has now stopped working I get "The device reported an error on a request to write data to media" followed by "an inconsistency was encountered in the requested backup file". Now the drive is totally full of transaction logs and my mail has stopped. I tried a different disk, and got the same result. After searching through the solutions I found that there is a 36GB limitation for saving backups D2D. The problem is that the data is now so huge that I can't back it up, therefore can't clear out the log files, therefore the drive stays full. And of course any thing I try takes forever before it eventually fails. I have Exchange Server 2007 on Windows Server 2003 Standard x64. I need some help. I am not an expert at Exchange administration, but I need to get this resolved ASAP. Thanks everyone.
