We are having an issue with our SQL backups. This is only happening on large databases. I found a thread that talked about one of the errors in the log and I performed the suggestion for Server 2003 found in that forum (http://support.microsoft.com/kb/304101) and the back ups worked until about 2 AM last night. Now it is throwing errors again. The log contents are below:
