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.
Vobcopy copies DVD .vob files to hard disk (thanks to libdvdread), decrypting them on the way (if libdvdcss is installed) and merges them into 2 GB files (or larger) with the name extracted from the DVD. It checks for enough free space on the destination drive and compares the copied size to the size on DVD (in case something went wrong during the copying). It can also mirror a whole DVD video part and copy single files.
SynchroDir is a backup and synchronization utility. Each backup is the subject of a recordable "backup project". This feature allows you to save projects corresponding to different computers, servers, external hard drives, USB keys, etc. You can also backup data of computer Y to computer Z from a controlling computer X. Each backup project includes an unlimited number of "jobs". At the end of the backup process, a log file is available. Each job has a source and a destination, each corresponding to a volume or a directory. The volume or directory must be "mounted", either locally or over the network.
backmeup is an easy-to-use curses backup script. It uses the simple concept of "backup destinations" (where files are backed up to) and "backup sources" (where files for backing up reside) which may be accessed either locally or remotely using URLs of the supported file-transfer protocols (eg. SSH, Samba, FTP). Once backup jobs have been configured using the interface, backmeup can be instructed to run in the background as a daemon, sending email reports on backup status as required.
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.
rdiff-backup backs up one directory to another. The target directory ends up a copy of the source directory, but extra reverse diffs are stored in a special directory so you can still recover files lost some time ago. The idea is to combine the best features of a mirror and an incremental backup. rdiff-backup can also operate in a bandwidth- efficient manner over a pipe, like rsync. Thus you can use rdiff-backup and ssh to securely back up to a remote location, and only the differences will be transmitted. It can also handle symlinks, device files, permissions, ownership, etc., so it can be used on the entire file system.
