Is it possible to upload a file to a website, but save it on a different computer?
I have a podcast site that I am working, but the host is starting to charge us extra for the backups due to MBs. So I was thinking of storing the audio files on a local computer, but have the information (mySQL data) on the main site.
You could certainly store files on a different server, just as long as you can access that server from your web server.
The files would still need to transit via your web server though, and you would presumably need some kind of security/authentication system on your file server to allow your web server to identify itself whilst preventing unauthorised access.
On the whole I would have thought that this is only really viable if you control the web server, otherwise it’s probably better to change provider.
