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.
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.
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.
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.
Clone2fs copies an ext2/ext3 file system to another volume or an image file. Unlike dd, clone2fs does not copy the whole volume but only blocks that are actually in use. Therefore, it is usually faster. It's also faster than dump/restore, tar, or similar backup software because it accesses the source and destination volumes sequentially most of the time.
Manent is an algorithmically strong backup and archival program. It features efficient backup to anything that looks like storage. Currently it supports plain filesystems ("directories"), FTP, and SFTP. Planned are Amazon S3, optical disks, and email (SMTP and IMAP). It can work (making progress towards finishing a backup) over a slow and unreliable network. It can offer online access to the contents of the backup. Backed up storage is completely encrypted. Backup is incremental, including changed parts of large files. Moved, renamed, and duplicate files will not require additional storage. Several computers can use the same storage for backup, automatically sharing data. Both very large and very small files are supported efficiently. Manent does not rely on timestamps of the remote system to detect changes.
