Hi,
seems the Backup problem with error code 0x80070002 struck me as well:
Backup fails with only 0x80070002 and no further information. I'm not doing a backup for the whole drive,
but for selected folders from several partitions (being on the same physical HDD).
I've read lots and lots of threads here, so here is what I tried so far and what I can give as information:
- System is Windows 7 Pro 64-bit
- trying to back up to 1.5 TB external HDD (Western Digital) connected via USB
- system has 8 GB RAM, but chipset is Intel P55 so I guess I don't have Nvidia-based USB
(device manager says "Intel(R) 5 Series/3400 Series Chipset Family USB Enhanced Host Controller - 3B34").
So I guess the Nvidia USB fix mentioned elsewhere does not apply as well
- concerning shadowcopy storage area:
Situation was that used/assigned/maximum size was nearly the same values, but I changed it to be the following (and it did not make any difference
after a reboot):
C:\Windows\system32>vssadmin list shadowstorage

- in another thread I found something about USN journal on system-reserved partition after having installed Acronis True Image Home 2010 (which I also tried and removed again). But my output for this is as follows:
C:\Windows\system32>fsutil usn queryjournal h:
Fehler: Das Datenträgeränderungsjournal ist nicht aktiviert.
- no dual boot configuration - system was a clean install of Windows 7-64-Pro, no other OS added afterwards
- I checked the registry for the paths for the profiles, seems to be alright (did not check this any more because of the workaround
I found (see below))
- did a chkdsk /R on all three source partitions (where I take data from for the backup) and on the target partition (on external HDD):
no errors found
What I finally found as a workaround the following:
If no drive letter is assigned to the small system-reserved partition (containing bcd), backup fails with the above
problem. Upon reboot, I also see error event 24620 from Bitlocker-Driver in the event log ("Überprüfung des verschlüsselten Volumes: Die Volumeinformationen auf "\\?\Volume{06d90073-b8bd-11de-be0f-806e6f6e6963}" können nicht gelesen werden.") where the volume id refers to the small
system-reserved partition (checked it in the registry when I (for testing) assigned a drive letter to that partition). Noteworthy that
I *NEVER* did anything with BitLocker (and remember, my version is Win7-64-PRO).
BUT if I assign a drive letter to the partition and reboot, I don't see the BitLocker error event in the log and backup works.
This behaviour can be reproduced (take away drive letter, reboot -> BitLocker error event, backup will fail. Reassign drive letter,
reboot -> no BitLocker error, backup works).
(Backup worked in the past when I tried it in order to compare it to more sophisticated tools, and I think at that time there also was no drive letter assigned to that partition, but I'm not 100% sure about this)
Can you please explain that? Of course I do not want to waste a drive letter for that partition only to make backup work.
Regards,
Mario
