An Error Happened When I tried to back up my computer onto a portable hardrive?

I was using the backup wizard/program in the control Panel on Windows XP when this error occurred.
“Error returned while creating the volume shadow copy:800423f1
Aborting Backup.”
What can I do about this??

-UPDATE 4/6/2011- COMMON PROBLEMS: “THE DATA COULD NOT BE READ. PLEASE TURN OFF THE POWER, THEN REMOVE AND REINSERT THE DS GAME CARD.” The solution for the problem: (Go to Options, Emulation Setup, NDS Cartridge Back up Media and change it to FRAM 32KBytes to get all games to work on No$ GBA Remember to go to options, save options and then press OK. This saves the setting you’ve made.) CAN’T SAVE? Check your BATTERY folder with all your game saves. Make sure after you’re done saving in the game that sav files appear in the BATTERY folder. I have a No$ GBA folder with everything in one folder and have a shortcut to No$ GBA.exe. Also make sure your No$ GBA.INP file is not manipulated. If anything is not working properly after that, just download No$ GBA and start again. GAME CRASHING? Check out the latest version of No$ GBA (version 2.6a), that is your best bet. I have found a link to No$ GBA 2.6a through a Google search below for you to use. The developer(s) seem to have halted development for No$ GBA, so your donations towards 2.6a would be unnecessary. I forgot to mention but No$ GBA also plays regular GBA games, you can find those roms in emuparadise too. Here are links to everything though.
