Thanks again, @<1523701070390366208:profile|CostlyOstrich36> . I understand, but the copy is not a backup of ClearML .zip parts rather a single .zip file. Is there a way to re-create/upload from disk ClearML .zip parts? For example, trying to split the single .zip using ClearML .zip parts size? Could the HASH be an issue? Can dataset 'synchronize' help in this case?

ClearML only keeps links to the data, so if you simply put the copy you have in the same paths, everything will work as before

Hi @<1751777178984386560:profile|ConfusedGoat3> , is the data itself still accessible anywhere in it's entirety?

Hi @<1523701070390366208:profile|CostlyOstrich36> . It seems at least one artifact from the dataset task (i.e., a .zip part) is damaged on disk. I can access both the File Server storage and I do have a separate copy of the dataset outside ClearML that I could use to re-create/upload from disk. Do you know if there is a way to re-create/upload from disk using the backup copy I have outside ClearML? Thanks a lot in advance for your support!
