Currently, ClearML says we use around 40GB (metrics storage), but if i analyze each task, and calculate the size of all metrics / logs it comes to around 2GB. Is this possible?

Not necessarily, since the data is parked inside databases. In theory, if done perfectly, then a new deployment will have the volume as the databases.

Thanks for the reply, should the export size (total GB) match the reported size in the UI?

Hi @<1884048732937261056:profile|StraightCrab57> , not automatically from the PRO. You would need to export everything manually via the API (Task details + events (scalars/logs/debug samples))

I would assume that your analysis is incomplete
