Transferring large files (1GB+) over internet, securely, one time only [duplicate]

Possible Duplicates:
Best method of transferring files over internet?
Free way to share large files over the Internet?

I have been asked to design a system for transfering large files (1GB+) across the internet. These files are pdf documents that customers need to download from my website.

I have never built anything like this before, and I'm not sure what hardware or software would be best suited to this, or whether it would be best to host it internally or externally.

Any advice or recommendations for hosting would be much appreciated.

Solution 1:

We use LeapFile: http://www.leapfile.com/

It is not free, but it is very reliable, and it works great. Read the "Why LeapFile" web page for more info: http://www.leapfile.com/why-leapfile

Solution 2:

You may want to keep this all in house - I would not put anything confidential 'out there' to be managed by another entity. Zendto may fit the bill:

http://zend.to/

The safe, secure and completely free way to transfer large files around the Web. ZendTo is a completely free web-based system, which you can run on your own server with complete safety and security. It runs from any Linux or Unix server or virtualisation system and there is no size limit and it will send files one and a half times faster than by email. It will also integrate with any Active Directory, LDAP or IMAP system you already have in place.

Solution 3:

well if downloading from a website you set up a website with files and links to them. you transfer/upload to the website via FTP you need anybody offering web hosting with the multiple GB space on it. people downloading download via a web browser.

or you could upload it to mediaupload.com or rapidshare, you may want to subscribe, for example a subscription may ensure it stays up longer. you then send out links to the files.

if you want some security, then, If using a website then perhaps links not publicly advertised or with obvious/guessable names is enough.

if encrypting files beforehand, well, I think axcrypt might be pretty good.
