Not Backed Up, Corrupt original

  • February 15, 2018

I try to sync my raw files with the cloud, but every time I get a message that says "Not Backed Up, Corrupt original". I can open every every file that seems to be corrupt without any problems via Mac Finder and also work with them in Lightroom CC, but it won't sync with the cloud.

I already updated Lightroom cc to version 1.2 and I tried to solve it with the known issues https://helpx.adobe.com/lightroom-cc/kb/known-issues.html#SyncingLightroomphotos

I also have done a lot of work on my picture and I don't want to waste that time. Is there any way to fix these issue? The Raw files are on a external disk, connected to the Macbook.

Best regards,

Florian

Hi Shweta,

Just wondered if there was a fix for this that you can share or any tips for customers with similar issues?

Thanks


Hello,

Unfortunately at this time, there is no fix for the issue apart from deleting and reimporting the pictures.

We aim to prevent this from happening.

In this case, it was because the external drive was disconnected before sync finished.

Hi, I am having this same issue but it is now 2025. I have hundreds of photos that were fine and now suddenly are saying that they are not backed up, corrupt, or missing the original file. They were fine yesterday before I connected my external drive just for a routine sync. I am wondering if there were any resolutions or fixes that have come up in the last 7 years. Thanks, Lily

I am using Lightroom 8.5.1 if that helps

Launching the latest 1.4 build should automatically correct the corrupt images that were incorrectly marked corrupt.

The one thing to keep in mind is that the hard drive containing the supposedly corrupt originals must be connected when launching in order for the corrupt assets to resolve.

I am running Lightroom 1.4 and am having this same issue. I just migrated from Lightroom Classic, and all of these images were migrated from there.

I tried making a copy of one of the images (a 7 MB JPEG), and it's been trying to upload that for over an hour now. This image, along with a bunch of others, came in with no capture date. The image is fine, I can open the original without trouble. Additionally, for this particular image, when I deleted and re-imported it, it suddenly came in with a capture date.

My biggest concern here is this happening again. I had to let go of my file structure to get into Lightroom CC, so I'm now highly dependent upon albums to find my photos now. If this continues to happen, I will quickly lose track of my images because I can't figure out which albums they were in before they got corrupted.

This is a major issue, and unless there is a resolution, is a deal breaker for me.

UPDATE: I went through the photos little by little, trying to find them in their originating albums (the ones I use to organize all my photos). It was huge a pain, because I could not determine just from the image what album they all belonged to. I've taken hundreds of pictures of squirrels or a sunset. But I finally got them all fixed and the sync errors seem to be gone now. However, now I'm not sure I can trust Lightroom with my photos. I would still like to know if this issue is being worked on, or if I should leave Lightroom.

I had the same issue, when I migrated 11k photos. I disabled the GPU support and then it worked much better.

Hi Florian,

See you have posted in the ‘other‘ (photoshop.com/getsatisfaction) forum also.

It’s probably worth adding the extra info above also as Adobe engineers monitor it often.

Sounds strange as my understanding is that LrCC imports and then syncs when it can.

Out of interest can you see the photos at Photo Editor | Online Photoshop Lightroom ?

Also what happens when you try to reimport one into LrCC, does it see it as a duplicate?

Hello Selondon,

Thanks for taking the time for helping me.

If I look at Photo Online Editor I see that there should some pictures, but the Raw files are missing. It looks like this:

It looks like the Metadata exists but the picture does not.

When I try to import the same picture again, it will be recognized as a duplicate. If I try to import the picture from the Lightroom CC Catalogue folder where the original pictures are, it will be still corrupt. But if t take the same picture and copy it to a different folder and import it, its not corrupt anymore and is uploading to the cloud. So it seems there is a bug in the database, because these pictures are definitely not corrupt, they are ok.

Can anybody help me with this?

Best regards,

Florian

Just to clarify, your steps were

-Imported the pictures from a SD card

-Disconnected the SD card

-Waited for these pictures to sync, and when they did, this "Not Backed Up, Corrupt original" did not appear

-Made changes to these pictures when you did not have internet

-While you were connected to the internet again and the images started to sync, the "Not Backed Up, Corrupt original" did appear.

Does this sound about right?

Also, are you able to export the images with the changes?

Hi Florian, can you give a little extra background so others can help... how are you trying to import the Original RAW into LrCC? What is your workflow? How many photos does this affect? What format are they? Also, is it possible to import from a local disc?

Hello Selondon,

Usally I Import my Raw files from a the SD-Card to an external SSD-Disk (Mac OS Extended (journaled)) connected with my Macbook. The pictures are made with an EOS M3, so its a Canon RAW file. The database .libary is still on the default folder. After that I adjust the pictures, export some of these and (because I am still traveling) if I have a good internet connection I will sync them with the adobe cloud via Lightroom cc. After a while I try to sync my pictures I get this message

I read about a bug, that if you work with adobe Lightroom CC and an external disk, if you disconnect the disk before a complete sync of the pictures, it creates this message. But the originals are not corrupt.

Lightroom tells me that I have to re-import the pictures. But then all of my work on every single picture is gone and I don't want to waste that time. There are around 2000 pictures affected.

Thanks for your help!

Best regards,

Florian
