Data Backup Digest

Some fundamental differences in file transfer affect how multiple users access networks or information systems. One of the biggest differences is between a file server, which facilitates file transfer over a network, and a File Transfer Protocol or FTP server which sets up effective data transmission over the Internet.

File Server and FTP Server Definitions

A file server is essentially a machine that acts as a data manager for other hardware devices or endpoints within a network. File servers handle file sharing in multiuser environments typically behind a company firewall. They can be stand-alone hardware components, or devices within a Storage Area Network setup.

FTP servers have the ability to enable files to be sent over the Internet. In many cases, these external file handling systems are set up for less sensitive types of data that may need to be accessed by suppliers, clients or others not directly connected to a business. Where a file server may be used in-house to keep a private network off of IP systems, FTP can allow managers to direct certain “more public” kinds of files out into the global web in order to reach a broader audience, albeit with the right kinds of security and authentication.

Options for FTP and Network Sharing

Aside from the essential difference between using a non-FTP file server or setting up FTP transfers, managers of IT systems also have additional options. Companies often use a technology like Virtual Private Network or VPN to set up an encrypted network connection in order to provide more security for data. It’s important to note, though, that tools like VPN typically only provide an “encryption tunnel” between two established end points that may not cover the entire “life cycle” of a file or data transmission.

By contrast, a simple FTP connection is not encrypted to provide comprehensive security. However, users can encrypt files for transmission over FTP or they can add something called Secure Shell or SSH, provided they have an established connection to the host. In addition, something called Secure FTP can provide encryption for the entire chain of transfer. This can also help to verify the identity of a client/server.

New Cloud Models and Other Advances

Many of those with an in-depth knowledge of various file transfer systems argue that FTP doesn’t really need to be used at all in most cases, considering it an “anachronism” in the face of new developments in cloud hosting and secure networking. The rise of new web-based data transfer models raise questions about the role of FTP technology in a world where virtual networks have created so many alternatives to the older IP connecting methodologies.

In the end, most corporate plans for file transfer rest on specific metrics and concerns about data access and security. Either a non-FTP file server or an FTP connection can make sense in different situations where file sharing is required. Professionals must look at what kinds of access need to be supported, and who will be utilizing connections on a regular basis.
