jtdavies Posted May 5, 2002 Report Share Posted May 5, 2002 I've been using Retrospect with my VXA-1 drive quite well for the last month. Today I tried backing up some very big video files - 6-8 gig apiece. For the biggest files I get compare errors. This happened for 5 files. I then tried backing up again and I got the errors on 4 files. Both the hard disk and the tape drive are on Firewire. I guess that I could keep trying to backup and maybe get lucky after a few more tries but I'm going through alot of tape. Is there something else that I can do to be more successful?

lv2ski Posted May 8, 2002 Report Share Posted May 8, 2002 What are the exact compare errors if you go to your operations log? This log can be found under the Window menu at the top of your screen in Retrospect, and then click on Log. Quote Link to comment Share on other sites More sharing options...

jtdavies Posted May 15, 2002 Author Report Share Posted May 15, 2002 Well... I tried duplicating the file from one drive to another drive five times tonight. The first time it failed on compare with the same type of error message. The next four times it worked without a problem. Quote Link to comment Share on other sites More sharing options...
