Data corrupts over time - corrupt data synced back to cloud?

Report · Jan 03, 2022

Hello all,

I have a catalog spanning around 10 years of pictures, around 70k pictures.

From time to time I see damaged pictures which have been definitely clean before.

I see strange color distortions or colored lines/bars across the picture, or sometime even white areas across the whole picture.

It looks like some of the pictures are even stored as such in the cloud 😮

Q1: Is it possible, if a original changes on disk locally (e.g. due to corruption in filesystem) that this "change" is the synced back to the cloud?

Q2: How can I selectively fetch a file from cloud to overwrite local original?

Thanks! Marco

UPDATE:

I have "simulated" such a local manipulation of an original inside the catalog under ../originals.

Such change is not synced back to cloud, which is good, as we can assume at any time that the cloud file remains clean.

But Lr does not notify that a file is damaged locally and does not refresh it from the cloud back to the local catalog.

Means: if you at any time export such files from the catalog to put it somewhere else, you export the damaged file.

It would be an easy improvement, if Lr just tracks the checksums of the local files agasinst the clean file in the cloud to notify the user that local data corruption happened. A possibility to refresh the local file would be nice. Or is that already possible today and I did not find it?
