welcome to the forum
summary:
-
cloud storage
rclone can do that. -
files encrypted before entering cloud storage, files decrypted and accessed locally
rclone can do that -
fast upload and download of small files
as per rclone docs, that is a limitation of google drive. not a limitation of rclone. -
sync/file streaming/mounting of cloud storage as a drive, (the same file in pc 1, pc 2 and cloud, so a change to the file in pc 1, pc 2 and cloud get the change to that file)
rclone can do that -
being able to make certain files and folders available for offline without losing folder structure, sync changes when going back online
if you download a files or folders to local, then it is available offline. rclone can keep folder structure.
afiak, the same would apply to rclone.
- rclone can do that
rclone mount is not desgined to emulate the offline feature of google drive desktop or microsoft onedrive desktop.
