Mac OS X & macOS names. As you can see from the list above, with the exception of the first OS X beta, all versions of the Mac operating system from 2001 to 2012 were all named after big cats.

Tar and Archive Utility also know how to convert the. files back to the native formats, but the. files are kept if the archive is extracted on another platform or on a non-HFS volume. You can usually just tell tar to remove the metadata by setting COPYFILEDISABLE to some value. Mac OS X Server 1.0 is a operating system developed by Apple Computer.Released on March 16, 1999, it was the first version of Mac OS X Server. It was Apple's first commercial product to be derived from 'Rhapsody'—an eventual replacement for the classic Mac OS derived from NeXTSTEP's architecture (acquired in 1997 as part of Apple's purchase of NeXT) and BSD-like Mach kernel. Tarmac virus - a trojan that targets macOS computers. Furthermore, there are many dangerous tasks that can be carried by Tarmac virus later on. This malware might slightly increase the power of your CPU and GPU, damage some files or software that is found on your macOS, install other viruses and infections, run multiple damaging processes in the background.

Terminal (Terminal.app) is the terminal emulator included in the macOSoperating system by Apple.^[1] Terminal originated in NeXTSTEP and OPENSTEP, the predecessor operating systems of macOS.^[2]

As a terminal emulator, the application provides text-based access to the operating system, in contrast to the mostly graphical nature of the user experience of macOS, by providing a command-line interface to the operating system when used in conjunction with a Unix shell, such as zsh (the default shell in macOS Catalina^[3]).^[4] The user can choose other shells available with macOS, such as the KornShell, tcsh, and bash.^[4][5]

The preferences dialog for Terminal.app in OS X 10.8 (Mountain Lion) and later offers choices for values of the TERM environment variable. Available options are ansi, dtterm, nsterm, rxvt, vt52, vt100, vt102, xterm, xterm-16color and xterm-256color, which differ from the OS X 10.5 (Leopard) choices by dropping the xterm-color and adding xterm-16color and xterm-256color. These settings do not alter the operation of Terminal, and the xterm settings do not match the behavior of xterm.^[6]

Terminal includes several features that specifically access macOS APIs and features. These include the ability to use the standard macOS Help search function to find manual pages and integration with Spotlight.^{[citation needed]} Terminal was used by Apple as a showcase for macOS graphics APIs in early advertising of Mac OS X,^{[citation needed]} offering a range of custom font and coloring options, including transparent backgrounds.

This article will show you how to do a full system backup with tar.

Backing up with tar has the advantages of using compression that can help save disk space, and simplicity. The process only requires several steps, they are:

1. Boot from a LiveCD
2. Change root to the Linux install
3. Mount additional (if any) partitions/drives
4. Add exclusions
5. Use the backup script to backup

To minimize downtime the backup can alternatively be performed on a running system using LVM snapshots,if all filesystems reside on LVM volumes.

Boot with LiveCD

Many Linux bootable CDs, USBs... have the ability to let you change root to your install. While changing root is not necessary to do a backup, it provides the ability to just run the script without need to transfer it to a temporary drive or having to locate it on the filesystem. The Live medium must be of the same architecture that your Linux install currently is (i.e. i686 or x86_64).

Changing root

First you should have a scripting environment set up on your current Linux install. If you do not know what that is, it means that you are able to execute any scripts that you may have as if they are regular programs. If you do not, see this article on how to do that. What you will need to do next is change root, to learn more about what changing root is, read this. When you change root, you do not need to mount any temporary file systems (/proc, /sys, and /dev). These temporary file systems get populated on boot and you actually do not want to backup them up because they can interfere with the normal (and necessary) population process which can change on any upgrade. To change root, you will need to mount your current Linux installs root partition. For example:

Use fdisk -l to discover you partitions and drives. Now chroot:

This example obviously uses bash but you can use other shells if available. Now you will be in your scripted environment (this is provided that you have your ~/.bashrc sourced on entry):

Mount other partitions

Other partitions that you use (if any) will need to be mounted in their proper places (e.g. if you have a separate /home partition).

Exclude file

tar has the ability to ignore specified files and directories. The syntax is one definition per line. tar also has the capability to understand regular expressions (regexps). For example:

Backup script

Backing up with tar is straight-forward process. Here is a basic script that can do it and provides a couple checks. You will need to modify this script to define your backup location, and exclude file (if you have one), and then just run this command after you have chrooted and mounted all your partitions.

Restoring

To restore from a previous backup, mount all relevant partitions, change the current working directory to the root directory, and execute

replacing backupfile with the backup archive. Removing all files that had been added since the backup was made must be done manually. Recreating the filesystem(s) is an easy way to do this.

Backup with parallel compression

To back up using parallel compression (SMP), use pbzip2 (Parallel bzip2):

Store etc-backup.tar.bz2 on one or more offline media, such as a USB stick, external hard drive, or CD-R. Occasionally verify the integrity of the backup process by comparing original files and directories with their backups. Possibly maintain a list of hashes of the backed up files to make the comparison quicker.

Restore corrupted /etc files by extracting the etc-backup.tar.bz2 file in a temporary working directory, and copying over individual files and directories as needed. To restore the entire /etc directory with all its contents execute the following command as root:
