In this video, Brian Behlendorf from Lawrence Livermore National Laboratory presents: Sequoia's 55PB Lustre+ZFS Filesystem. Recorded at LUG 2012 in Austin.

CopyFS aims to solve a common problem : given a directory, especially one full of configuration files, or other files that one can modify, and which can affect the functionning of a system, or of programs, that may be important to other users (or to the user himself), how to be sure that a person modifying the files will do a backup of the working version first ? This filesystem solves the problem by making the whole process transparent, automatically keeping versionned copies of all the changes done to file under its control. It also allows a user to select an old version of the files, for example to repair a mistake, and allows him/her to continue edition from this point.

SoftNAS™ is business-class network attached storage (NAS) delivered as software as a service.  The NAS software virtual appliance runs within your cloud computing environment (e.g., Amazon EC2) or local virtual server environment (e.g., VMware vSphere) and manages the available raw disk storage, providing enterprise-grade storage capabilities. SoftNAS leverages a number of open source technologies, including ZFS on Linux.  ZFS on Linux is a port of the popular ZFS filesystem originally produced by Sun Microsystems and released with OpenSolaris.  SoftNAS builds on the robust, solid foundation of ZFS and its powerful, extensible Linux foundation.

Lsyncd watches a local directory trees event monitor interface (inotify or fsevents). It aggregates and combines events for a few seconds and then spawns one (or more) process(es) to synchronize the changes.
