TRIXER creates catalogs of transparent file indexes. A transparent file index is an exact mirror of a directory, except that each of its file is void, thus "taking no space", while apparently having the same size of its indexed counterpart so as to describe it fully. This is accomplished by combining sparse files support with fusecompress on-the-fly compression technology. This is useful for many purposes, e.g. creating a catalog of your CD/DVD-ROM library to browse its contents without having to physically access it. The advantage of this software is that a TRIXER catalog is a plain mountable ext2 filesystem, allowing enhanced interoperability with the huge lot of available software to handle the catalog in a number of ways.
vm-image-manage is a simple script for managing a small cluster of Xen virtual machines on a single host with one command. It's optimized for repeatedly restarting a virtual machine slot with an image. It features templates for Xen configuration files. It speeds the import and export of Xen images to tgz archives. It speeds frequent redeployment with rsync. It manages mounting domains when the VM is down and un-mounting when the domain is launched.
wget can be used to download a Web site, with all pages referenced by the originating one, but it saves all pages in a directory tree (or single directory). The intention of web-archive-creator is to join the power of wget and the usability of the .war format, which Konqueror is able to browse. The Web ARrchive format is simply a tarred and gzipped file containing the Web files. The web-archive-creator script performs the download with wget and writes an index.html linking to the starting pages/URLs wget fetched.
Lsyncd watches a local directory tree's event monitor interface (inotify). It aggregates and combines events for a few seconds and then spawns one (or more) process(es) to synchronize the changes. By default, this synchronization is done with rsync. Lsyncd is thus a lightweight live mirror solution that is comparatively easy to install. It does not require new filesystems or block devices and does not hamper local filesystem performance.
The Zumastor Linux storage project adds enterprise storage features to Linux, primarily improved snapshots and remote replication. Point-in-time, near zero-cost, block level snapshots can be added to any existing filesystem and performance does not degrade with multiple snapshots. Remote replication is achieved by sending minimal block level deltas between snapshots without having to traverse the entire filesystem like rsync does.
NexentaStor is a unified storage solution that installs on standard hardware and provides enterprise class storage at a fraction of the cost of legacy, proprietary storage solutions. NexentaStor is particularly well suited for virtualized environments thanks to the ability of NexentaStor to eliminate duplication of primary data storage, to manage the storage for virtual environments from one interface, and to leverage SSDs to address the random I/O and boot storm issues with virtual environments.
