VSS services must be running to do a Open File Backup process. It makes a shadow copy of the files while they are open (like many windows files) so that you can back everything up.
There are a couple of things you can do to fix this problem. Warning: do you have IE 7 installed? If you do you must uninstall it before running SFC /scannnow at the command prompt. SFC is a system file checker that will reinstall the system files from your Windows CD, but if you have installed IE7 and what is on your CD is IE6, you will end up with a mish mash of files that is hard to sort out. Nevertheless I did it. Best to uinstall IE7( IE6 comes back automatically), run SFC /scannow, then reinstall IE7
There is a really marvelous program to fixes a host of dll registration problems and starting services like the VSS and +DCOM and the "Insufficient Permissions Problems" that you might experience after doing a "Repair" of windows (not SFC, but a repair" If you are having any problems with Windows UPDATES or Explorer or Windows Installer, this is the place to go. Go to http://wiki.djlizard.net/Dial-a-fix (I was instructed to do this by a level two Microsoft Technician who said this is the tool to fix up all these issues) and download Dial-a-Fix and also the permissions repair tool secedit.exe. The program turns off services, reregisters all the dll's. then restarts the services. Just click the green button to have all registrations redone (but uncheck "adust time and date"). This takes about 10 minutes, program is free. The permissions repair tool took about 1 hour on my three drives, but after I ran that, all my VSS and "Insufficient Permissions" backup problems disappeared. I sent Djlizard the writer of Dial-a-fix $25. What a miracle program.
I have a Dell 4600 and upgraded from my failing original SATA 120GB to a Seagate SATA 300GB (ST3300631AS). I use Dantz Retrospect 7.5 to backup to a Maxtor external USB drive. I used Acronis Easy Migrate 7.0 to clone the drives. Every time I tried to backup, Retrospect would say "preparing backup" then I would get the blue screen of death (BSOD) error saying "Bad_Pool_Header Stop: 0x00000019".
1. Go to windows Device Manager 2. Click "view" and select "show hidden devices" 3. Scroll down to "storage volumes" 4. Click on the plus to expand. 5. Click on each one listed and right click and uninstall. (you will get a message on some staying to reboot before it takes effect. Select no until you do them all.) 6. Reboot. 7. Wait till windows automatically reinstalls devices. Will prompt to reboot again. 8 Reboot. Now it should work.
The problem was they got corrupted using DiscWizard and Acronis (which is the DiscWizard engine). There are other explaination at that site, but the above works WITHOUT A REINSTALL OF WINDOWS OS!!!!
Thank you, thank you, thank you! I didn't use your 'uninstall' scheme but I did go to the Wilder Security URL and used MBRFix to 'generatesignature' and that fixed the Shadow Volume problem. I suspect re-registering the drive would have worked as well but I was curious to see what else MBRFix could do.
