Backup Windows 7 not possible, error code 0x81000101

Question

Backing up Windows 7 impossible, it stops at 7% and after a while  a time out message will be shown with code 0x81000101. I tried everething as specified by cdobbs on earlier questions, no result. The external  backup disk, usb connected,  is 150 Gb, clean and formatted.  Backing up mine laptop, (Windows XP ) no problem at all. To copy C to the backup drive will not succeed either due to open system files, e.g. hiberfile.sys, pagefile.sys, ntuer.date etc. Any solution ? 

Answer 1

This error can occur if the Shadow Copy services are not running. The backup applications and System Restore depend on these services.
Perform the following.
Open Control Panel.
Click the Classic View in the Tasks pane.
Double click Administrative Tools.
Double click Services.
Scroll down and double click the Microsoft Software Shadow Copy Provider.
In the Startup Type menu, select Automatic.
Click the Start button.
Click Apply / OK.
Next, scroll down to the Volume Shadow Copy service and perform the same steps.
Exit everything and reboot the computer.
IF that doesn't work
Did your computer come with a Recovery Partition on the drive? (Check the computers documentation)
If it did, you cannot have any backup software or System Restore set to backup or monitor that drive.
Go to Control Panel.
Click on Classic View in the Task Pane.
Double click System.
Select Advanced System Settings in the Tasks Pane.
Click the System Protection Tab.
In the Available Disks section, make sure that the backup partition is not selected. If it is, remove the check mark.
After this is done or if this does not work, go to Start/All Programs/Accessories/System Tools and click on Disk Cleanup.
In the Options dialog, select 'Files from all users on this computer'. Click the C: system drive. When the scan is completed, click the 'More Options' Tab. In the 'System Restore and Shadow Copies' section, click the 'Cleanup' button. In the 'Are you sure......' popup, click Delete. Click OK.
Wait for the Disk Cleanup to complete.
Now, go back into Disk Cleanup and follow the same procedure for any other drives that appear in the drop down menu where you selected the C: drive the first time.
Exit everything and reboot the computer.
After the computer reboots, check System Restore again. If System Restore is still not working, go back into System Protection and turn off System Restore for all drives and reboot the computer again. This will delete all restore points on all drives.
After the reboot, go back and enable System Restore for the C: volume only. Create a new restore point for that drive.
Let me know the results.
