CreateFile() failed with 1920

my incremental backups are failing with the error message:

CreateFile() failed with 1920

how can I figure out what this means? Some other information: this only happens for files that live somewhere underneath a Dropbox folder. The full error line looks like this:

2019.05.01 21:34:29.027 (UTC-8) 3 7                             Context: \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy39\Users\peterldowns\Dropbox (MIT)\6008\.git\objects\4c\3d43fd19e44d5db5b82cb4ea7f59ee4c367747

If that file path looks scary, here's one for a more regular file

2019.05.01 21:34:28.596 (UTC-8) 2 5                     \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy39\Users\peterldowns\Dropbox (MIT)\2018-08-25 Aarons\2017-04-11 03.34.06-2.jpg

Hoping to fix this, please let me know how I can help.

Peter

Oh, interestingly, it looks like these are attempts to copy Dropbox "currently online but not offline" files. As in, they have little gray indicators on their icons showing that while Dropbox is showing them to me, they have not been synced to my device.

Error 1920 is "The file cannot be accessed by the system. " These being under Dropbox's control and offline would certainly explain it.

I'm getting this same error with Dropbox files. All of them are in a cache folder. Dropbox is not running.

The files are being copied from an external USB hard drive which used to be an internal drive. I upgraded in size, and am using Bvckup2 to restore the Dropbox contents to the new drive before I turn it back on again. (Avoiding unecessary bandwidth usage.)

I can only guess that Dropbox locked down the access to these files with restrictive privileges and, perhaps, assigning them to a custom user account. That is, they are owned by some other user AND they are set to be accessible to that user only. In this case accessing these files from any other account would require changing DAC/Owner on them, even if running with full admin privileges, and this is not something bvckup2 can do.

I'm getting these same errors all of a sudden. Nothing has changed with my Dropbox account, that I know of. Did you ever find a resolution?
