1) Questions and Answers : Windows : What to do after a power cut (Message 35103)
Posted 25 Sep 2008 by Profile Kevin Rigotti
Post:
My part of town had a power cut today at 1126. I do have a backup from 0630 this morning.

Should I restore anyway, even though everything seems to be running normally, just in case something was corrupted?

Or, is the software resilient enough to untidy shutdowns that I should leave it alone?

Is there a way of telling if any data has been damaged?

If you make big automated backups of everything while BOINC + model are running there\'s no guarantee that the BOINC folder contents (or BOINC6 Data folder contents) will be restorable after a crash. I think that ghosted backups made with BOINC running are more likely to be restorable.

To be certain of restorability it\'s worth stopping the model and exiting from BOINC every couple of days, then backing up the contents of the BOINC (or BOINC Data) folder. The READMEs linked in my signature contain a collection about backups.

I apologise if you already know all this!


Vista\'s built in backup does a shadow copy so should be OK (?)
I admit I hadn\'t read the README\'s (thanks for the reminder).
It was only 3 days in, so I wasn\'t too attached to it.

Another computer with the same characteristics as yours (i.e. Intel/Windows) has gone further in that work unit: 7605224, so it probably isn\'t an ice world. That isn\'t, of course, to say that the graphics aren\'t icy blue! A normal crash will do that as well - the Defender crash may have done for the model.

If you have a backup, it would be worth giving that a go.


Sadly, I have only ever done a weekly backup at home - now that I\'m doing this it might be a good point at which to change to daily - so as it\'s probably broken I\'ll abort the stuck task now and free up a chunk of CPU for a new one.

Possible iceworld, but may be more broken than that. Had a Windows Defender crash yesterday evening and a subsequent boot problem until full power off and repairs by chkdsk, so the data files may have been compromised.

Model time and date shown as 00/00/0000 00:00 ?!

Result ID:http://climateapps2.oucs.ox.ac.uk/cpdnboinc/result.php?resultid=7605217
Timestep: 154081
s/TS: 1.43
Colour: Blue
CPU: Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz [x86 Family 6 Model 15 Stepping 11]
No overclocking.

I\'m happy to let it continue over the week-end to see what happens. If it still looks stuck on Monday I\'ll abort it.
