Windows XP Professional instillation: BOINC has been running slowly on my computer for a while (at least 8 months on two simultaneous projects, which are not yet half way through, on a reasonably high spec computer that runs 18 hours a day). And the BOINC manager icon appears twice in my system tray for some reason.

So I decided to back up the whole BOINC folder, delete the original, reinstall BOINC from scratch with a new BOINC application download, and then copy my original \'Projects\' folder back into the BOINC folder.

Lo and behold, but my projects were reset to zero.

So, I deleted the new BOINC folder, restored the entire BOINC folder.

And hey presto! after a restart, both projects are still at zero.

Then to top it of I accidentally aborted one of the projects.

Is there any solution to this?

Thanks

When you backup the BOINC folder, make sure that the project is not running at the time. If you did that, then restoring the BOINC folder should let you run the project from exactly the point (minus a few minutes) where it was backed up.

CPDN project slowing down may be caused by extreme fragmentation. I defragment and backup regularly, about once a week.

Craig, I\'m no expert but I think you did it the wrong way round - i.e. you should instal the new BOINC version into your existing folder, rather than the other way round. Personally, I\'m not brave enough to try doing that in the middle of a model though, I\'d wait till my model finished!

Hi Craig

If you have a properly made backup it should be possible to sort this out. Did you exit from boinc before you made the backup? If you did exit, the backup should be fine and restorable. If you backed up with boinc active (ie the icon still in the system tray bottom right of screen), the restore won\'t work.

Assuming your backup was a good one, you can attempt the restore as many times as you want. Have a look at Les Bayliss\'s easy manual method through the link in my sig. Go to the README about avoiding crashes and it\'s the first item.

Just to make sure we\'re talking about the same thing: cpdn is a project. The climate models are workunits.

Before you restore your backup into your new boinc download, you\'ll see from what Les says that you have to first empty out/delete all the contents of the new boinc folder. You then fill up the empty boinc folder with your backup (which consists of the contents of your old boinc folder).
