Note that users are required to login for data downloading, even to download public data.
When using an asynchronous request, the system stores the products for a period (~ 7 days) before deletion. This allows the final user to be able to resume a download process from an already existing request. This can be a useful functionality if the whole requested data to be downloaded has a large size and the internet connection is not very stable. Currently this functionality is only available by using Firefox browser or curl.
Every user has a disk quota of 60GB, if the maximum disk quota is reached, the download asynchronous requests will fail. Users may contact helpdesk for assistance.
