The rdiff-backup script maintains a backup mirror of a file or directory either locally or remotely over the network on another server. rdiff-backup stores incremental rdiff deltas with the backup, with which it is possible to recreate any backup point. [33] The librsync library used by rdiff is an independent implementation of the rsync algorithm.
Back In Time is a backup application for GNU/Linux with a graphical interface written in Qt and a command line interface. It is available directly from the repositories of many GNU/Linux distributions. Released under the terms of the GNU General Public License (GPL), it is free software.
dd is a command-line utility for Unix, Plan 9, Inferno, and Unix-like operating systems and beyond, the primary purpose of which is to convert and copy files. [1] On Unix, device drivers for hardware (such as hard disk drives) and special device files (such as /dev/zero and /dev/random) appear in the file system just like normal files; dd can also read and/or write from/to these files ...
In computing, tar is a computer software utility for collecting many files into one archive file, often referred to as a tarball, for distribution or backup purposes. The name is derived from "tape archive", as it was originally developed to write data to sequential I/O devices with no file system of their own, such as devices that use magnetic tape.
Bacula supports Linux, UNIX, Windows, and macOS backup clients, and a range of professional backup devices including tape libraries. Administrators and operators can configure the system via a command line, GUI or web interface; its back-end is a catalog of information stored by MySQL, PostgreSQL, or SQLite.
A backup includes metadata like owner/group, permissions, POSIX ACLs and Extended file attributes. It handles special files also - like hardlinks, symlinks, devices files, etc. Internally it represents the files in an archive as a stream of metadata, similar to tar and unlike tools such as git .
A shell script is a computer program designed to be run by a Unix shell, a command-line interpreter. [1] The various dialects of shell scripts are considered to be command languages . Typical operations performed by shell scripts include file manipulation, program execution, and printing text.
Bash can execute the vast majority of Bourne shell scripts without modification, with the exception of Bourne shell scripts stumbling into fringe syntax behavior interpreted differently in Bash or attempting to run a system command matching a newer Bash builtin, etc. Bash command syntax includes ideas drawn from the Korn Shell (ksh) and the C ...
