I require a small space online (free) where I can
upload/download few files automatically using a script.
Space requirement is around 50 MB.
This should be such that it could be automated so I can set
it to run without manual interaction i.e. No GUI
I have a dynamic ip & have no tech on setting up a server.
Any help would be appreciated. Thanks.
A number of online storage services provide 1-2 GB space for free. Several of those have command-line clients. E.g. SpiderOak that I use has a client that can run in a headless (non-GUI) mode to upload files, and there's even a way to download files from it by wget or curl.
You just set up things in GUI mode, then put files into the configured directory and run SpiderOak with right options; files get uploaded. Then you either download ('restore') all or some of the files via another SpiderOak call or get them via HTTP.
About the same applies to Dropbox, but I have no experience with that.
