All files are being missed. The files ranges from simple text files to autocad drawings.
Like I said this only happens on certaion directories, but nothings on the server has changed sonce upgrading to V12.5
if multiple file types other that database files are randomly being skipped (is it different files each time, or the same ones over and over?) I'd try a repair install of BackupExec followed by the latest service pack
if that doesn't fix it, I'd open an incident at Symantec
