Sorry for setting off some of your spam alarms....but this concept of autosynchronizing file systems is VERY cool....and quite a few of those in this list have asked me questions on how you would be able to achieve just such an action....I also apologize if some of you got more than one copy....
I've been playing with some new systems that do fileserver (CIF aka microsoft networking, and NFS) file system aggregation. The concept is that a device (software or hardware) will front end multiple file systems and then present them to users via a CIF or NFS interface. So that's the aggregation portion....but these new systems also provide a way to have a multitide of such aggregation servers (they don't have to front end another server...you can also just present the local file system on the aggregation server) that will auto synchronize those file systems. So the scenario is that Radiant Data Systems has a linux system that allows you to synchronize a file system across a wide area network. After the initial synchronization, it only sends the changes to lower your overall bandwidth utilization. In addition this secure communication provides a way to apply rules on how fast/often/etc these file systems need to be sync'd and provides a simple way to keep your file systems sync'd, no matter how many systems you may have. Sooooo....I've arranged for a presentation: When: June 26th, 6pm to 8pm Where: Kuykendall rm 303 Who: Anyone interested...no rsvp necessary What: Presentation on the technology and product How: Just come on down, invite friends..... http://www.radiantdata.com/ /brian chee University of Hawaii ICS Dept Advanced Network Computing Lab 1680 East West Road, POST rm 311 Honolulu, HI 96822 808-956-5797 voice, 808-956-5175 fax
