Yes, that sounds like a good start, DilapidatedDucks58 can you open a github issue with the feature request ?
I want to make sure we do not forget

I was thinking mainly about AWS.

Meaning S3?

yeah, I was thinking mainly about AWS. we use force to make sure we are using the correct latest checkpoint, but this increases costs when we are running a lot of experiments

will do

Thank you!

any chance StorageManager could re-download files only if their size is different from file in cache (as an option)?

I think there is force argument, to force download.
I think the main issue is getting the size from different backends (i.e. s3 /https / etc.)
Maybe we should add it as a GitHub feature request issue?
The main limitation is that the driver "list()" does not return file size.
For example it might be an issue with the default http files-server.
wdyt?

yes
