I use Windows 7 Backup & Restore on a weekly basis to back up my C-drive to an external drive. After working flawlessly for several years, suddenly I get the error message "Windows backup failed while trying to read from shadow copy on one of the volumes being backed up. Please check in the event log for any relevant errors."
I checked the event log but obviously don't know what I should be looking for. I am at a loss. Any help/guidance would be appreciated. Thanks in advance..........

First thing to do is scan the PC disk drive (source) for errors. Right click on the drive in Windows Explorer and check for errors. Reboot if needed to scan while not in use. Bad sectors can cause backup errors.

-steve Steve, I scanned the C drive for errors. Results were: 635,648 files processed 0 bad files 2 EA records processed 57 reparse records processed No bad sectors I do not understand what is meant by EA & reparse records. Are these problems I should worry about? Also, my virus detection program (AVG) tells me I have no files in quarantine, which I understand can cause backup problems. What do you suggest I do next? Thanks..........

Go into Disk Management and check the amount of Free Space is present for the System Reserved volume. Sometime if this gets too low, the backup will fail.

I could not find a System Reserved volume; further research indicated that this volume is generated when you do a clean install of Win 7. I did not do a clean install.....it was an upgrade from Vista Ultimate. However, I'm happy to report that I just finished a successful backup. This happened after I did the scan Steve mentioned and after I deleted the contents of the Java cache folder, as another user recommended. So for now my problem is solved........thanks to you and Steve for your prompt responses.

Thanks.......... EA records and reparse records are part of the scan -- these are file system items. Glad to read that you were able to resolve it. -steve _________________ stephen boots Microsoft MVP 2004 - 2020 "Life's always an adventure with computers!"

Each week before doing my Win 7 backup, I had to go in and once again delete the contents of the Java cache folder. So I finally just removed Java from my computer. The only difference I notice is that my automated weekly backups are now successful. Thanks again........

Removing Java - good call.
