Transfer data between Dropbox and S3
Hi, I have a newbie question:
* Is it possible to transfer data from S3 to Dropbox and vice versa, ideally programmatically in Python. It would be great, if possible, to achieve it without the ...
We can't provide support for S3 itself, but if you can get a link to a file on S3, you could then pass that link to /2/files/save_url to save the linked file to Dropbox, without downloading it locally. That's available as files_save_url in the official Dropbox API v2 Python SDK.
That can be used by any kind of Dropbox account, so any plan would be fine. You'd just need to consider how much storage space you need.

- I have a huge database (total size is more than 200T), which is stored on Amazon AWS S3, and I want to transfer that data from AWS S3 to Dropbox business. Is there any effective and efficient way to achieve it?

ygnmax We don't have anything built specifically for S3 like this, so if you're a programmer and want to write something to do this, the method in my previous comment would probably be a good option to use.
Hi. If you don't mind me asking, did you find a solution for this?
You can use the script below to transfer your data to DropBox.
