You could boot into safe mode and try copy/paste. Sometimes it will work from safe mode.
Do you have the Windows Home cd? By default, Home doesn't install the back-up utility. You have to install it manually.
1.After inserting the CD-ROM, open Control Panel's "Add or Remove Programs" utility. In the "Add or Remove Programs" utility", click on the "Add New Programs" button, then click on the "CD or Floppy" button.
2. In the "Run Installation Program" dialog box that appears, navigate to the VALUEAD/MSFT/NTBACKUP folder on the CD-ROM and select the file NTBACKUP.MSI. Click on the "Finish" button. The Backup utility will be installed.
