metastore is a tool to store the metadata of files/directories/links in a file tree to a separate file and to later compare and apply the stored metadata to said file tree. It was originally written as a supplement to git, which does not store all metadata, making it unsuitable for e.g. storing /etc in a repository. metastore can also be helpful if you want to create a tarball of a file tree and make sure that "everything" (e.g. xattrs, mtime, owner, group) is stored along with the files.
cdrtools (formerly cdrecord) creates home-burned CDs/DVDs with a CDR/CDRW/DVD/BluRay recorder. It works as a burn engine for several applications. It supports CD/DVD/BD recorders from many different vendors; all SCSI-3/mmc- and ATAPI/mmc-compliant drives should also work. Supported features include IDE/ATAPI, parallel port, and SCSI drives; audio CDs, data CDs, and mixed CDs; full multi-session support; CD-RWs, DVD-R/-RW, DVD+R/+RW, BD-R/BD-RE; and TAO, DAO, RAW, and human-readable error message
Utility to help create backups more easily. The idea of the program is that all essential information for creating a backup is in a single file. It can use ‘tar’ for creating archives, has a command line interface, and supports incremental backups.
libzip is a C library for reading, creating, and modifying zip archives. Files can be added from data buffers, files, or compressed data copied directly from other zip archives. Changes made without closing the archive can be reverted. The API is documented by man pages. It includes a tool to modify zip archives from the command line.
Arkiv is a simple backup program that allows you to backup files and MySQL databases on the local disk drive, and to archive your data on Amazon S3 and Amazon Glacier. It's possible to backup at the pace you want, as often as each hour. Complex purge policies could be set to delete local files and files archived on Amazon S3. It's written in Bash shell script. Configuration process and log files are as user-friendly as possible.
Tomb is a system to make strong encryption easy for everyday use. A tomb is like a locked folder that can be safely transported and hidden in a filesystem. Its keys can be kept separate; for example, you can keep the tomb on your computer and its key on a USB stick. Tomb is written in code that is easy to review and links shared components: it consists of a ZShell script and desktop integration apps; it uses standard GNU tools and the crypto API of the Linux kernel (dm-crypt) via cryptsetup.
PeaZip is a cross-platform compression and archiving tool. It utilizes code from 7-Zip, Pea, FreeARC, PAQ, QUAD and UPX. Besides having full 7z, lzma, xzip, gzip, bzip2 and standard ZIP and TAR support, it can also read from APK, ZIPX, ARJ, CAB, CPIO, LZO, RAR, ISO, JAR, XAR, ACE, ARC, and various application or file system containers. AES256 encryption is further supported in some archive types, or splitting and merging, converting between formats, or secure archive content deletion, and creati
Lzip is a lossless data compressor with a user interface similar to the one of gzip or bzip2. Lzip is about as fast as gzip, compresses most files more than bzip2, and is better than both from a data recovery perspective. The lzip file format is designed for data sharing and long-term archiving, taking into account both data integrity and decoder availability.
Inno Setup is a tool to create installers for Microsoft Windows applications. innoextract allows to extract such installers under non-windows systems without running the actual installer using Wine. innoextract currently supports installers created by Inno Setup 1.2.10 to 5.5.6. innoextract is able to unpack (most) GOG.com installers, Wadjet Eye Games installers (to play with AGS), Arx Fatalis patches (for use with Arx Libertatis) as well as various other Inno Setup executables.
libburnia is a project comprised of libraries and binaries for reading, mastering, and writing optical discs. It provides libburn, a CD/DVD/BD burn library, libisofs, a manipulation library for ISO 9660 filesystems, and libisoburn, a ISO 9660 multi-session library. On top of them there is cdrskin, a cdrecord emulator, and xorriso, a all-in-one application for ISO 9660 multi-session operations which additionaly provides a limited emulation of mkisofs.
Barchive provides version control system functionality for binary data. It can deal with huge binary file blobs, partially supports git-like push and pull semantics, provides an immutable data store, which can be used in conjunction with rsync and other backup tools.
O2 is a flexible and encrypted archiving system for personal data like contacts, account and credit cards, Wi-Fi passwords, etc. It allows categorization of stored entities, regrouping, adding new meta info, object data relations, sorting and searching, import and export, or report/summary generation.
DACT is a compression tool designed to compress a file dynamically, choosing the algorithm that works best per block of input data to produce an overall smaller output file.
rsync is a replacement for rcp (and scp) that has many more features. It uses the "rsync algorithm" which provides a very fast method for remote files into sync. It does this by sending just the differences in the files across the link, without requiring that both sets of files are present at one of the ends of the link beforehand.
