Skwish is a fast, simple, lightweight Java library for storing blobs on the file system. It allows multiple concurrent readers and writers, provides all-or-nothing write semantics, and is designed to survive abnormal, unclean shutdown. Skwish is a structured implementation of storing all blobs in a single file to save on file system I/O. Skwish is premised on the proposition that blob storage ought to be orthogonal to the task of indexing. It is meant to be a clean and simple store on which some other index can be built.
The dsnapshot script provides a high-level interface to the Linux Logical Volume Manager. It uses its block-level snapshot support to create directory snapshots. In contrast to block-level snapshots, directory snapshots resemble the file system layer. Thus, you can snapshot any directory that is on a logical volume without worrying about the actual logical volumes, mount points, and paths.
EXIficient is an implementation of the W3C Efficient XML Interchange (EXI) format specification written in the Java programming language. The EXI format is a very compact representation for the Extensible Markup Language (XML) Information Set that is intended to simultaneously optimize performance and the utilization of computational resources.
csync is a bidirectional file synchronizer for Linux. It allows the user to keep two copies of files and directories in sync. It uses uses widely adopted protocols like SMB or SFTP so that there is no need for a server component of csync. It is a user-level program which means there is no need to be a superuser. With pam_csync, it is possible to create roaming home directories.
Telemeta is a global audio archiving program which introduces useful and secure indexing methods to back up digitized audio files and metadata dictionaries. It is dedicated to backing up any digitized and documented sound from collections of vinyls, magnetic tapes, or audio CDs over a strong database in accordance with many standards. Export functions also encapsulate edited metadata into a compressed file. The object style architecture provides easy developed user-friendly interfaces and a plugin style audio processing.
CAN is a packaging program that uses a format similar to JAR, but with some improvements. CAN uses only existing, open source tools for its implementation. It packages any executable and libraries, supports executable CANs, and can even tweak environment variables before execution.
The epitome suite consists of several discrete pieces that provide storage deduplication services. Deduplication is defined as the elimination of redundant data. The idea behind epitome is to provide a WORM-based archive/backup mechanism that is lossless and offers permanent storage with inherent data protection properties. Additionally, it provides several metadata formats and back-ends to meet several usage models. It provides a number of services to enable three major archiving technologies: CAS, SIS, and DEDUP.
