I know that Insync is for synchronising local and remote copies of files on Google Drive, however I'm interested in an alternative use case: using the Gdrive as an external disk, i.e. not syncing local files but simply storing them remotely. I currently have 1TB on Gdrive and using it via Insync means I have to dedicate 1TB locally as well, often for files I only refer to very occasionally. I understand the performance penalty of doing this, and of course the occasional availability issues that might arise, but that's a cost I would be happy with in certain situations.
As a possible variation: let the user dedicate up to X amount of local space and simply use it as a write-through cache, deleting the least recently used files when it fills up.
Is there some combination of options that will allow me to do this with Insync? Would there be any point is requesting it as a feature?
