Thanks for your reply and the hint to use MinIO, John!

However, you're advicing me to use --output-uri ? ClearML explicitly states the following deprecation warning when I tried that earlier:

> clearml-data create --project first_project_data --name project1  --output-uri S:\Unfinished_Learning_Data\clearml-storage
clearml-data - Dataset Management & Versioning CLI
Creating a new dataset:
Warning: '--output-uri' is deprecated, use '--storage' instead
...

Also note that the clearml-data create command accepts the --storage parameter even though it's not listed as a parameter in the documentation you linked.

I'm getting the feeling the documentation (and possibly code?) isn't entirely on par for the deprecation of --output_uri in favor of the --storage parameter. What's your thoughts?

Hi @<1864479785686667264:profile|GrittyAnt2> , for that you would need to specify --output-uri in the create command - None

This will point all previews also to the storage of your choice. Note, however as a NAS is considered part of your local disks, the browser cannot access local disk and therefor previews will not work.

For local storage solutions I suggest using something like MinIO

To iterate and fill you in with some more info:

• The data is successfully uploaded to S:\Unfinished_Learning_Data\clearml-storage - I can see it in the file system.
• I am able to download the data with a clearml-data get --id xxxxxx command.
• When changing name of the NAS folder to S:\Unfinished_Learning_Data\clearml-storage-tempchanged, it is not possible to download data anymore - I get Error: Could not load Dataset id=xxxxxx state . This is good and expected.
• However, with the NAS folder name changed to S:\Unfinished_Learning_Data\clearml-storage-tempchanged, it is still possible to see a preview of the PNGs in the dataset in the ClearML app interface! Cache is disabled. This is very confusing to me. It makes me worried that I don't have control of my data.
