Two weeks isn't really old in this forum, so it's alright.
Also, in mid-game you often get "Copy large database" missions. Yes, you would need a lot of back and forth trips, but once you've done it and got the precious cashmoneys, you can simply delete all of that stuff (just go to the console and use "cd usr" and "delete"). Of course, you only get console access with an admin account which will get you traced, but if you just use the normal file server thing, you should be able to delete all files manually. It just takes a bit longer. Your username for that mission will be valid forever.
Or you could, you know, abandon the mission and use the file server for your own means anyway.
If you need even more space, you can use both the target system and your employer's system. I'm sure they won't mind.
