shidewa Posted August 16, 2002 Report Share Posted August 16, 2002 We use Retropect Workgroup 5.5 on a Win2000 server machine. The clients are Win2000 professionnal computers and macintosh computers. The problem is that the log file show this error : Sample of the Retrospect log file : + Recycle backup using Network minimum (Documents) at 2002-08-12 17:00 To backup set Backup Set Monday... 2002-08-12 17:00:00: Recycle backup: The backup set was reset - 2002-08-12 17:00:00: Copying BackupDirectory on TELECHARGEMENT 2002-08-12 17:00:00: Connected to TELECHARGEMENT 2002-08-12 20:01:24: Snapshot stored, 998 KB 2002-08-12 20:01:30: Comparing BackupDirectory on TELECHARGEMENT File "C:\BackupDirectory\ file1.wav": didn't compare at offset 2 899 352 in stream "Data" File "C:\BackupDirectory\ file2.wav": didn't compare at offset 2 915 736 in stream "Data" File "C:\BackupDirectory\ file3.wav": didn't compare at offset 269 720 in stream "Data" File "C:\BackupDirectory\ file4.wav": didn't compare at offset 679 320 in stream "Data" And so on… It happens on one machine only. The computer is a Win2000 professionnal machine. I backup only one folder on that computer. And it's not all the files in the folder that have this error. All of the others clients works ok with no errors. What does the error “didn't compare at offset’’ usually means ? Thanks Link to comment Share on other sites More sharing options...
lv2ski Posted August 16, 2002 Report Share Posted August 16, 2002 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. Verification errors which mention data or resource offsets (such as "File 'Bore Dimensions': didn't compare at data offset 263 078" or "File 'Port Flow specs': didn't compare at resource offset 731 429") usually indicate problems with the communications bus. See SCSI Issues in the user's guide or error 102 in the knowledgbase for more troubleshooting steps. If you have a G3 upgrade card in an older Macintosh it may be the cause of errors mentioning an offset. Link to comment Share on other sites More sharing options...
