Have you ever wished you could replicate non database files on your servers?

By Andrew Pollack on 08/01/2007 at 09:52 PM EDT

I've been using a tool called "unison" to keep the files on a pair of linux servers in synchronization. Its available for Windows as well though. This is a command line utility that works very much like Domino replication. A hash database is used and compared rather than a simple look at file dates and names, so renames, deletes, changes, and new files are all replicated effectively.

I'm using it at the file system level to keep not just the files in the domino/html directory in sync, but also several other directories on my linux machine including my /etc/asterisk files. This allows me to have a very up to date failover solution that includes not just Domino but also the PBX, echo server, and all the other things those machines do. Its really helpful for moving things from test into production as well.

For more information, Linux Journal has a good technical article on it.

IBM has made a deal under which the Notes & Domino software and intellectual property is now being developed and maintained by HCL America. HCL America is part of the very large "HCL Technologies" company that has grown from its roots in India to become an 8 Billion Dollar company with a global presence in the IT Industry.

If your company has ditched Notes and Domino, I feel sorry for you. For companies that do use Notes/Domino this is a game changer and Apple should be paying attention. Here's why: There are hundreds of little Notes client applications you'd never spend the time and money to build and deploy for your internal user base on IOS that we use Notes for all the time (those of us still using it). Now, those are suddenly ALL available on the iPad. ......
