The dump command is a program on Unix and Unix-like operating systems used to back up file systems. It operates on blocks, below filesystem abstractions such as files and directories. Dump can back up a file system to a tape or another disk. It is often used across a network by piping its output through bzip2 then SSH.
Some backup software looks at the date of the file and compares it with the last backup to determine whether the file was changed. Versioning file system: A versioning filesystem tracks all changes to a file. The NILFS versioning filesystem for Linux is an example. [49]
Copy backup. backs up the selected files, but does not mark the files as backed up (reset the archive bit). This is found in the backup with Windows 2003. Daily backup. incremental backup of files that have changed today. Data salvaging/recovery. the process of recovering data from storage devices when the normal operational methods are impossible.
pax is an archiving utility available for various operating systems and defined since 1995. [1] Rather than sort out the incompatible options that have crept up between tar and cpio, along with their implementations across various versions of Unix, the IEEE designed a new archive utility pax that could support various archive formats with useful options from both archivers.
In CP/M, the meaning is inverted: creating or modifying a file clears the archive bit, and the bit is set when the file is backed up. Backup software may provide the option to do a full backup while clearing archive bits – that is, to back up all files regardless of their archive bit status, and to clear the archive bit for all 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.

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. The Borg project has created extensive ...
