i think you confuse with filestorage which is what most hosts forbid, plainly storing files on public_html with no webhosting content for purposes like backup or fileshosting service etc.
i dont think andy claimed theres unlimited storage, only unlimited database, if he said unlimited webspace then thats a different story. Andy probably want a host that offers non restrictive amount of database instead of restrictive since andy probably has several database and assuming increasing too and dont want such limitation.
Andy: if you are looking for shared host i dont think ive seen non overselling host that offers 100gb space.
While it may or may not violate their terms of service, if you have a limited number of developers accessing it via IP then that might work.
If/when the host complains or takes your site down then you could go to a different host and re-upload.
Or an uber cheap dedicated server, then the host would not complain.
Thanks everyone. I google "unlimited database hosting" but most of the hosts I have never heard of.
I know most hosts link the database to their disk space that's why it's a bit tricky to find it.
I ask this because I have a problem I want to solve. I want to share a huge database with a group of people. So instead of asking each one to download the 1oo+ GB of data and install a local server on their machine, put it online would make coding much easier.
