[[System-administration::backup]]

Backupninja: Backupninja allows you to coordinate system backup by dropping a few simple configuration files into /etc/backup.d/. Most programs you might use for making backups don't have their own configuration file format. Backupninja provides a centralized way to configure and schedule many different backup utilities. It allows for secure, remote, incremental filesytem backup (via rdiff-backup), compressed incremental data, backup system and hardware info, encrypted remote backups (via duplicity), safe backup of MySQL/PostgreSQL databases, subversion or trac repositories, burn CD/DVDs or create ISOs, incremental rsync with hardlinking.

Backuppc: BackupPC is a high-performance, enterprise-grade system for backing up GNU/Linux machines and laptops to a server's disk. Its features include clever pooling of identical files, no client-side software, optional compression for using even less storage, support for a full set of restore options, and a powerful Apache/CGI user interface.

Bacula: Bacula is a set of programs that allow you to manage the backup, recovery, and verification of computer data across a network of different computers. It is based on a client/server architecture and is efficient and relatively easy to use, while offering many advanced storage management features that make it easy to find and recover lost or damaged files.

Bar: bar stands for Backup And Restore. This programme has been designed for a user who desires to backup his Home folder each week or day using cron or a similar programme and transferring those backups at the end each month to another medium for safer storage.

Barman: Barman (backup and recovery manager) is an administration tool for disaster recovery of PostgreSQL servers written in Python. It allows one to perform remote backups of multiple servers in business critical environments and help DBAs during the recovery phase. Barman's most wanted features include backup catalogs, retention policies, remote recovery, archiving and compression of WAL files and backups. Barman is written and maintained by PostgreSQL professionals 2ndQuadrant.

Bloat: 'Bloat' is a Perl script which analyses an archive's filename, and extracts it using a suitable extractor. It also supports several other features, such as "subdirectory detection", MIME-type checking (via 'file'), and extraction of non-trivial archive types.

Bluraybackup: bluraybackup makes a decrypted copy of the whole Blu-ray Disc Movie or it extracts a decrypted version of a specific BDMV stream. Inspired by dvdbackup, developed in C99 following the suckless philosophy.

CacheIt: This is a candidate for deletion: I cannot confirm any facts about this project. The URLs on this page link to web pages which do not work without running JavaScript which does not have any licence notice. I have been unable to download the program, suggesting it might be dead. Drw (talk) 09:37, 18 July 2018 (EDT) CacheIt is a PHP class to facilitate caching. You subclass Cachable and implement the get method of Cachable, and you instantiate it as well as instantiate CacheIt with arguments of the instance of your subclass of Cachable. Then both the path (ending in a trailing slash) to the directory that cached data will be kept, and the number of seconds that a cached entry can be kept before expiring. Then, just call the get method of the instance of CacheIt and caching happens automatically. CacheIt doesn't do LRU--if you're concerned about the cache directory getting too large, have a cron job scan it occasionally and delete the oldest files.

Ccd2cue: The program ccd2cue is a CCD sheet to CUE sheet converter for the GNU Operating System. It supports the full extent of CUE sheet format expressiveness, including mixed-mode discs and CD-Text meta-data. It plays an important role for those who need to use optical disc data which is only available in the proprietary sheet format CCD, but don’t want to surrender their freedom. It fills an important gap in the free software world because before its conception it was impossible to use complex forms of optical disc data laid out by CCD sheets in a whole/holy free operating system.

Ccollect: ccollect does (pseudo) incremental full backups with different exclude lists, using hard links and rsync.

Cedar Backup: 'Cedar Backup' supports backups of files on local and remote hosts to CD-R or CD-RW media over a secure network connection. It also includes extensions that understand how to back up MySQL databases and Subversion repositories, and can be easily extended to support other data sources. It is focused around weekly backups to a single disc, with the expectation that the disc will be changed or overwritten at the beginning of each week. With appropriate hardware, Cedar Backup can also write multisession discs.

Chpox: 'chpox' provides transparent checkpointing and restarting of processes on GNU/Linux clusters. It was originally designed for recovery of jobs with a long execution time in case of system crashes, power failures, etc. It works with openMosix, is SMP safe, works as a kernel module, does not require kernel patches or program recompiling/relinking, and supports virtual memory, regular open files, pipes, *nix domain sockets, current directory, termios, and child processes.

Confstore: 'confstore' is a configuration backup utility. It scans a system for all recognised configuration files and then stores them in a simple archive. It knows what to scan for by reading a definitions file. Confstore can also restore configuration from backup archives it has previously created, upload them to a FTP server, and mail them to an email account.

Core-restart: 'core-restart' is a process checkpointing and restarting system. It does not require the executables to be linked with a library, so processes can be checkpointed without being changed. Also, the restarted process and the restoration code are in independent address spaces which simplifies the mechanism of restoring the stack and register state of the checkpointed process. The system runs only on user-level code and requires no modifications to the kernel.

Cpio: Cpio copies files into or out of a cpio or tar archive. The archive can be another file on the disk, a magnetic tape, or a pipe. GNU cpio supports the following archive formats: binary, old ASCII, new ASCII, crc, HPUX binary, HPUX old ASCII, old tar, and POSIX.1 tar. The tar format is provided for compatibility with the tar program. By default, cpio creates binary format archives for compatibility with older cpio programs. When extracting from archives, cpio automatically recognizes which kind of archive it is reading and can read archives created on machines with a different byte-order.

DACT: 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.

DIAP: DIAP (Distributed Internet Archiving Protocol) is a set of Bash shell scripts to set up a system using three backup nodes either between sites (e.g. between offices and homes) or over WANs. The application provides a decentralized, self-contained and managed storage utility. The emergence of a DVTL (Distributed Virtual Tape Library) is the end result. Nodes can be dedicated to storage or used for existing services over unused bandwidth. The scripts are a toolkit to help users set up their own project, and to help the writer improve the system and work in user space over SSH.

DIBS: DIBS is a backup system that protects your data by giving your files to peers (and in return, you store their files) so that if a catastrophe strikes your area, you can recover data from surviving peers. This solves the problem of mirroring your data by adding more disks to your own computer only ot have a fire, flood, power surge, etc. wiping out your local data center. Note that DIBS is a backup system, *not* a file sharing system like Napster, Gnutella, Kazaa, etc. In fact, DIBS encrypts all data transmissions so that the peers you trade files with can not access your data.

Dar: 'dar' is a shell command that makes backups of a directory tree and files. Its features include splitting archives over several files, CDs, ZIPs, or floppies, compression, full or differential backups, proper saving and restoration of hard links and extended attributes, remote backup using pipes and external command (such as ssh), and rearrangement of the "slices" of an existing archive. It can now run commands between slices, scramble archives, and retrieve individual files from differential and full backups.

Ddrescue: Ddrescue is a data recovery tool. It copies data from one file or block device (hard disc, cdrom, etc) to another, trying hard to rescue data in case of read errors. The basic operation of ddrescue is fully automatic. That is, you don't have to wait for an error, stop the program, read the log, run it in reverse mode, etc. If you use the logfile feature of ddrescue, the data is rescued very efficiently (only the needed blocks are read). Also you can interrupt the rescue at any time and resume it later at the same point.

Dkopp: Dkopp is a program used to copy or back-up disk files to DVD or BD (Blue-ray) media. Full or incremental backups can be done, with full or incremental media verification. A GUI is used to navigate through directories to select or de-select files or directories at any level. Backup jobs can be saved for later re-use. New, deleted, and updated disk files are handled automatically, without re-editing the backup job. An incremental backup updates the same DVD/BD media used for a prior full backup. Files can be restored to the same or another location on disk. Large backup jobs can be done using multiple DVD media.

Dobackup.pl: 'dobackup.pl' is a script to run unattended incremental backups of multiple servers. It handles multiple media sets with automatic media preparation and rotation, configurable 'what-to-backup', global per-host exclusion patterns, and user settable 'don't-back-this-up' metafiles. Its design goal is zero-maintenance, ideally leaving the user with nothing to do except change the media when told.

Dtrx: 'dtrx' intelligently extracts many different archive types. It will get the contents from tar, zip, rpm, deb, and cpio archives, as well as compressed files, with one simple command. It helps keep your filesystem sane by putting every file's contents into a dedicated directory, and making sure the owner can read and write whatever's extracted. It can even recursively extract archives. To use dtrx you'll need the usual tools for the archive types you want to extract: for example, if you're extracting zip files, you'll need zipinfo and unzip. See the INSTALL file included with dtrx for a complete list.

Dump Restore: This package contains both 'dump' and 'restore'. 'Dump' examines files in a filesystem, determines which ones need to be backed up, and copies those files to a specified storage medium. 'Restore' performs the inverse function; it can restore a full backup of a filesystem. It can also layer subsequent incremental backups on top of the full backup, and restore single files and directory subtrees from full or partial backups.

DupeFinder: ' DupeFinder' locates, moves, renames, and deletes duplicate files in a directory structure. It's good both for users who haven't kept their hard drives very well organized and need to do some cleaning to free space, and for users who like to keep lots of backup copies of important data "just in case" something bad should happen.

Duplicity: 'duplicity' is an incremental backup tool that backs up files and directories by building tar-format volumes and uploading them to a file server. By default, these volumes will be GPG encrypted, although simple gzipping is also supported. It supports local, FTP, and ssh/scp back-ends. Because it uses librsync, archives only record the parts of files that have changed since the last backup. It supports deleted files, full Unix permissions, directories, symbolic links, and fifos, but currently not hard links.

Dvdisaster: 'dvdisaster provides a margin of safety against data loss on CDs and DVDs caused by scratches or aging. It creates error correction codes to compensate read errors which are not correctable in the CD/DVD drive. It also reads as much data as possible from defective media; typically, it handles up to 10% unreadable sectors (relative to the overall medium capacity) using its error correction code. Hardware requirements for running 'dvdisaster' include:
-x86 compatible hardware in 32bit mode -an up-to-date CD or DVD drive with ATAPI or SCSI interface -at least a P4 at 2Ghz or comparable processor -file system without the 2GB size limit for handling DVD images

E

The program e is a command line utility that extracts lots of different archives. It is very simple and can be extended very easily.
It is inspired by how firewall use their rulesets, and works like this:

For each file that has to be extracted, the rules are matched one after the other.
When a rule matches (either by the filetype or filename), the command is executed.
If the command does not return an error code the extraction is considered successful, otherwise the next rules are matched.
It currently has rules for zip, rar, 7zip, gzip, bzip2, rpm, cab, arj, ace, ppmd, lzo, tar.bz2, tar.gz, ar, cpio, dar, uharc, zzip, and many more.

EMirror: 'EMirror' is an ftp-mirror script that can produce HTML, PHP, or text logfiles. It supports most kinds of FTP daemons (including EFTP), and re-get. Other features include the ability to download just the latest version of a file, mechanisms that will keep from downloading very old files, support of regular expressions for including/excluding files, special watermarks for deleting files, and multi-threading. This package was formerly known as the ECLiPt Mirroring Tool.

Easy Backup: Easy Backup is a simple backup utility in Python designed to make backing up the same set of files over and over again fairly easy. To accomplish this, Easy Backup reads a tasks file that can define several backup tasks and what files are part of those tasks. Making a backup is then simply a matter of executing the program from the command line and telling it what task to backup and where to back it up to.

Ebiso: ebiso is simple tool for creating bootable ISO images for UEFI based systems running GNU/Linux. It can be however used as standard ISO image creator as well.

Electric Sheep IO: ElectricSheep.IO is an (hopefully) simple tool to execute backup tasks and copy archives offsite. It's designed to operate from a single utility machine over the network or the Internet using SSH.

Ext2hide: ext2hide allows the user to save and restore an arbitrary number of files to and from the reserved space in an ext2/3 filesystem's primary and backup superblocks. Using ext2hide, you can use this reserved section to store an arbitrary number of files, where they will be completely invisible to normal filesystem utilities, but still residing in permanent storage on disk. This can be useful for passwords, public keys, anything you like.

Fileprune: 'Fileprune' deletes files from a collection, targeting a given distribution of the file timestamps within time as well as size, number, and age constraints. It is meant to keep a set of periodically-created backup files to a manageable size while still providing reasonable access to older versions. The algorithm used for pruning is based on an exponential, Gaussian (normal), or Fibonacci distribution, and provides fine control of the files to delete and allows the retention of recent copies and increasingly aggressive pruning of older files. The retention schedule specifies the age intervals for which files will be retained.

Filewatcher: 'filewatcher' maintains a local file archive repository. A configuration file details which files and directories to monitor and to whom reports should be delivered. It is useful in situations where there are multiple sysadmins, each of whom should know as soon as possible what changes the other have made. Correcting or rolling back to the previous version is trivial.

Flexbackup: 'flexbackup' is a configurable and easy to use Perl-based backup tool, that can backup local files as well as remote machines (using ssh). It allows the backup itself to be made with afio, cpio, tar, dump, star, or pax. It can work with tape drives, or can easily archive to on-disk files.

G4L: G4L is a hard disk and partition imaging and cloning tool similar to Norton Ghost and (tm) by Symantec. The created images are optionally compressed, and they can be stored on a local hard drive or transferred to an anonymous FTP server. A drive can be cloned using the Click'n'Clone; function. g4l supports file splitting if the local filesystem does not support writing files 2GB. The included kernel supports ATA, serial-ATA, and SCSI drives. Common network cards are supported. It is packaged as a bootable CD image with an ncurses GUI for easy use.

G4u: g4u ("ghost for unix") is a boot-floppy/CD that lets users clone hard disks by using FTP. This is often done to deploy a common setup on a number of PCs. The floppy/CD uploads the compressed image of a local hard disk to an FTP server, and then retrieves that image via FTP, uncompresses it, and writes it back to disk. Network configuration is fetched via DHCP. The hard disk is processed as an image, so g4u can deploy any filesystem/operating system. Users can clone local disks as well as partitions.

GMail Archiver: GMail Archiver is a tool for archiving IMAP, mbox files, or Mailman archives to a GMail account.

GNOME Schedule: GNOME Schedule is a system schedule maintenance tool. It has support for the cron and at scheduling systems. It aims to be as HIG compatible as possible. The target is to provide any sane desktop user with a tool to maintain the scheduling of his or her desktop tasks, while not requiring an understanding of the cron or at subsystems.

GPRename: 'GPRename' is a GUI batch file renamer based on Gtk-Perl. It can rename files numerically, insert/delete characters at/between specified position(s), replace strings (either using regular express or not), and change case.

Gfslicer: 'gfslicer' slices and then deslices large files, mainly for use with removable storage media. Files can be sliced to any arbitrary size and then transferred using floppies, etc. The sliced files can then be desliced to the original form with the same name and extension. A checking mechanism helps avoid errors. You can tar folders and then slice them within gfslicer and the same in reverse (i.e., deslice and untar not slice and tar). Tar and untar can be used separately. A log file facility is also included to cross-check what happened already. You can also can drag and drop any file into gfs window and get it sliced.

Gitenc: Gitenc is a simple shell script that works as a placeholder for git add and will parse filenames for sensitive names from git diff and apply GPG encryption as needed (filenames matching config, connection or sqlbackup) while handing everything off to git.

Glastree: The poor man's daily snapshot, 'glastree' builds live backup trees, with branches for each day. Users directly browse the past to recover older documents or retrieve lost files. Hard links compress out unchanged files; modified files are copied verbatim. A prune utility effects a constant, sliding window.

Gnetic: Gnetic is a tool for creating and restoring backups. Also lets you clone computers over the network. You can make computer copies using a direct connection between two machines (Point-2-Point), or using the "link mode", which creates a chain of nodes that sends information like a bus-topology net. With this method, theoretically you can clone up to 64 computers (or as many as you specify) in the same time that 1 or 2 take.

Gnochive: gnochive is a GNOME frontend for all common archivers under GNU/Linux. It supports gzip, tar, bzip2, zip, and compress.

Gofoss.net: gofoss.net is a beginners guide to free software, privacy, data ownership and durable tech. Learn how to: safely browse the Internet; keep your conversations private; protect your data; unlock your computer's full potential; stay mobile and free; own your cloud; avoid filter bubbles, surveillance & censorship.

Greenclone: greenclone copies windows hierarchies, handling hard and soft links, permissions, afs, VSS shadows and very long filenames. It was written to get round problems with programs like robocopy, and/or ports of unix programs like rsync. It can optionally store permissions and afs information in an auxiliary file so backups don't lose information even if the destination is not an NTFS partition.

Grsync: Grsync is a GUI for rsync, the command line directory synchronization tool. While it can work with remote hosts, its focus is to synchronize local directories.
