Error backing up data; dual boot related?
First, apologies if this is the wrong forum for this; Backup & Recovery seems like Maintenance, so I put it here.
I have been using the built in Windows 7 backup feature for several months without any problem. My last successful backup was on March 6th. The last attempted backup on March 13th (set on weekly schedule) failed for the following reason: "The volume for a file has been externally altered so that the opened file is no longer valid." The details show an error code of 0x800703EE. Every attempt to manually back up fails within a minute for this reason.
My backups all go to a big external hard drive connected by USB. I haven't had any problems like this in the past. Searching on Google reveals very little concrete info about what this means or how to fix it, although quite a few people seem to have come across it. The most informative post on the subject was this, which has the following solution:
Issue is resolved. The root cause was error in bcd, bcdedit was giving "The volume for a file has been externally altered so that the opened file is no longer valid" when trying to /enumerate active. Fixed it manually by building new BCD and doing a import followed by reboot. I guess windows backup internally tries to enumerate BCD and fails without correct log/message when enumeration is not successful.
Backup is running fine now.
Will reproduce specs from my profile below:
System Manufacturer/Model Number
Asus K50ID Notebook
Windows 7 Home Premium 64 bit
Pentium Dual-Core T4400
NVIDIA GeForce GT 320M
15.6" laptop screen
1x 320 GB internal (Samsung HM321HI SCSI) with a 17 GB recovery partition, 75 GB Windows 7 system partition, 192 GB data partition, and 36 GB Ubuntu 10.10 partition.
1x 500 GB external (Western Digital 5000AAK "MyBook") connected by USB.

I have independently come upon what may be a fix. I had a related problem with hibernation after setting up dual boot that required me to set the Windows OS partition to active. After that, I tried backing up, and it created a brand new backup... the old ones are gone, but that's OK.
This might be a fix for this issue. Just putting it out there in case someone runs across this topic while looking for a solution to this problem.
