With the open-source file synchronization tool Unison, you can easily keep files synchronized in multiple places locally and on remote machines.

By Max Hetrick

The cardinal rule of IT is to keep backups of your files. But how can you easily manage multiple locations of working copies of files? Here's where file synchronization comes into play at your desktops and servers.

The importance of preserving data combined with the inconvenience inherent in most backup solutions leaves room for new contenders.

I've chronicled my frustrations with backup software, but there's a new kid on the block. You'll like the kid's cache, too, when I explain the opportunity (deal) we have arranged for readers of MC TNT Tips 'N Techniques.

It's one thing to access SQL Server data from the System i, but it's another thing to access System i data from SQL Server.

By Joe Pluta

Heterogeneous data is one of the hallmarks of today's IT. Whether due to disparities in disk price or processing power, data in many shops has become fragmented across not only multiple physical machines, but multiple platforms and databases. One of the primary jobs of any IT department is allowing seamless access to those different databases.

Forget that proprietary network hardware.

Ask a thousand computing professionals what company name is synonymous with networking, and I'd wager that the vast majority would reply "Cisco." That Cisco has that kind of mind share must be very gratifying to its marketing department. While I can't argue that Cisco makes some very fine networking equipment--it obviously does--I'm not as enthused about the licensing under which the equipment is delivered. I can re-sell the hardware, but the embedded software is licensed, thus making the resale value of the equipment relatively worthless. To me, the cachet of the Cisco name is not worth the price, particularly if you keep in mind that the protocols used to deliver packets from one network to another are standard stuff. Because of the cost, building a Cisco-equipped lab with which you can study networking is outside the budget of most IT professionals.
