NetCache news..... Network Appliance and Zack Network Enhance Delivery of Personalized, Real-Time Content iCAP-enabled Application Provides Rapid Web Content Retrieval and Reduced Latency in Enterprise Environments SUNNYVALE, Calif. & SAN MATEO, Calif.--(BUSINESS WIRE)--Aug. 29, 2000--Network Appliance, Inc. (NASDAQ: NTAP - news), the leading provider of network-attached data access and content management solutions, and Zack Network, the Internet's leading server-side infomediary company, today announced that the two companies will develop a new enterprise solution enabling companies to mobilize their corporate intranets and distribute other content to company employees easily and efficiently. Network Appliance and Zack will use the open standards Internet Content Adaptation Protocol (iCAP) to integrate Zack's applications and services with Network Appliance(TM) caching devices. Zack's applications will be stored at the edge of the network, better enabling the delivery of personalized, real-time content and functionality to enterprise environments. Because traffic data is stored and updated on the NetCache(TM) C1100 solution, users can access customized content quickly and reliably. With this approach, enterprise employees can access valuable corporate information such as stock updates or company-wide messages by simply clicking on a logo at the bottom of their screens. There is no need to navigate a corporate intranet - the information is cached and delivered to users directly from the network layer. iCAP is an open protocol that enables communication between edge content devices, such as Web caches, and application servers that modify content for the edge device. Companies that use these scalable, content-aware, intelligent applications will be able to create new revenue opportunities by delivering value-added services such as family-friendly online services and prioritized traffic management. These solutions are built primarily for large ISPs, online advertising networks, enterprise and corporate networks, portals, and Web sites. ``By using iCAP to integrate Zack's services and applications with the NetCache solution, we can empower enterprises with a persistent communications tool, supplying users with unprecedented reliability and accessibility to information,'' said Amit Pandey, senior director of NetCache marketing at Network Appliance. ``The iCAP-enabled solution mobilizes customized corporate content and offers a single-click solution for retrieving information.'' ``Our integration with NetCache and iCAP allows enterprise customers unparalled access to value-added applications on the Zack platform,'' said Jason Campbell, chief technology officer at Zack Network, Inc. ``Zack's applications conveniently gather and deliver customized content, such as human resources information, the company directory, announcements or stock quotes, with the simple click of an icon, increasing employee efficiency and productivity.''

I am guessing that with WAFL, these root inodes are not changed to point to new data until a much later date, thereby allowing the operating system to access these old root inodes (which point to previously changed / deleted data)... Very close, Justin. Actually what ONTAP does is copy the INODE to disk at the time of SNAPSHOT (controlled by sys admin). (This takes milliseconds) and in effect preserves the file system image at that point in time. All blocks being pointed to by an INODE remain unchanged and undeleted until no INODE (SNAPSHOT) points to them. Then they are returned to the pool of free blocks for re-use. SNAPSHOT is useful for: Perform a SNAPSHOT of a database, then perform a backup of that database, which results in a consistent backup with no interruption of production, or run reports against that SNAPSHOT, which results in consistent reports with no interruption of production. End users can retrieve old versions of their files from the SNAPSHOT directory without asking sys admin to mount a backup tape for restore. ...and more.
