Deduplicator is a simple and efficient data deduplicator that works by hard linking files that have the same content. It is ideal for reducing the size of backups. It can save and restore intermediate results, so you can run it in a few short intervals, and allows you to review changes before they are committed to disk.
Gfarm is a distributed filesystem, generally used for large scale cluster computing. It's implemented in userland, and can be mounted by FUSE. It utilizes locality of a file to access a data node, and supports Globus GSI for Wide Area Network. Users can explicitly control file replica location on Gfarm. Gfarm can be used as an alternative storage system to HDFS for Hadoop, Samba, MPI-IO, and GridFTP. Monitoring via ZABBIX and Ganglia is also supported.
Chnorm is a simple command line utility for setting the owner, group, and the mode of given files and directories on a per file/per directory basis, recursively. It is especially useful if you often copy files with brain-dead permissions from filesystems not supporting the Unix permission scheme. It detects executables based on their contents and sets their permissions accordingly.
sortsamples is a utility that solves the problem of having many sample CD/sample library directories with each having kick, hi-hat, snare, etc. folders (leading to sampledirectorychaosmadness). With many sample directories, you ll be slapped around many directories hunting for kicks/hi-hats etc. This utility creates symbolic links to directories which are similar. This way, you can have all your kick. It was made because external Sample organizing utilities can also become a pain, because usually your DAW also has a sample browser in it. It would be nice to have structure at the source: the filesystem. This is a crazy effort to combine similar folders and categorize automatically.
losetup-utils are three bash scripts that attempt to make the use of losetup a bit easier and faster. losetup can be fast, easy, and practical if you need to transport sensitive information over the Internet or in CD's, DVD's, or a pendrive. Also, if you want to store private data on your hard disk or in the cloud, an encrypted volume can be a convenient choice. The types of encryption can be any installed on the system.
fswalker is an indexer and query tool for large filesystems. On large filesystems it is impossible to run tools such as du and obtain results in a reasonable time. fswalker crawls over a filesystem and populates a SQLite database containing information about each file. The fsq utility can then be used to query the database and obtain information much faster. It is intended that fswalk be run in a periodic manner so the sysadmin can monitor changes in the filesystem and produce reports.
