compare errors you will get information on these errors.




More importantly, you do not have to worry. The file that got the error in the compare stage, still got copied, and will restore.




"C:\WINNT\system32\Perflib_Perfdata_334.dat" I do not know what this file is. If it's important - then close the file and try to back it up again (it sounds like a database that was open...but I cannot tell).

So it was live and running. That is why you got an error on it.




After making copies of all files to be backed up, Retrospect goes back to the source and rereads each file and compares it to the corresponding file read from the backup media. If they are not identical, Retrospect displays an error.Retrospect will try to copy any files that don't verify during the next normal backup to this backup set. If the error is a different modify date or time (such as "File 'Home.html': different modify date/time.") then the file was most likely modified or saved between the original backup pass and the compare pass. The file will be recopied at the next backup.
