Question: I recently uploaded my personal photos to google photos but it seems it did not upload all my photos. I have around 20k photos so manual checking is not feasible.
I tried removing the data folder under the AppData for Google Photos Backup app to rescan the local folder but it hasn’t helped.
Then I did following:
I can’t just try to find missing files by name because the local files were in many different folders with same names i.e. different photos but same name due to reset of the camera sequence number.Also, the md5checksum retrieved from Google Drive is different than the local checksum (checked on few known files), I guess this is because Google Photos does not store the original version with unlimited free storage settings.
So how do I find these missing 4k files which are not uploaded.
Some other things. When I reset the Google Photos Backup desktop uploader application by removing its data folder from AppDate/Local/Google/Photos/…, it triggered a long rescan of the current folder. In the application log, I also found lines like these..
[98000] id 9: Stream summary:POST request: https://www.googleapis.com/plus/v1whitelisted/media/batchSearch (200)Post data size: 603[98000] Local Hash Dedupping: ?D:OneDrivePicturesCamera Roll20150706_022055815_iOS.jpg ?: Media exists ?D:OneDrivePicturesCamera Roll20150706_022416250_iOS.jpg ?: Media exists
and there were around 19k files with status “Media exists” but my program listed only 16k files so that’s a huge difference.
Also, the above log statements suggests that there is some form of hash comparison being performed by the google photos desktop application to detect what files have been uploaded or missed. But then google drive checksum is different than local checksum so how can google photos application can use this checksum?
I know there are around 400 small files that have been filtered but this still does not explain the difference of 600 or 3600 files.
So I have the following numbers…
Can somebody help.
Answer: Google Photos automatically removes duplicates (same name doesn’t count), perhaps use “Duplicate File Finder” to check your photos for duplicates with 100% match.
Also, are you sure that you only have 400 small files? I had a similar problem but it turned out I had a lot more small files than I thought.
I did a bit of testing and found that the smallest file that can be uploaded with the Desktop Uploader has a minimum resolution of 512px in either width or height.
Eg:
- 511 x 511 – Will not upload with Desktop Uploader* ?
- 512 x 1 – Will upload ?
- 1 x 512 – Will upload
*Workaround: upload using web-browser
