How to Use Tar Command Effectively in Linux For Good Backup Solution
The Linux tar command stands for tap archive, is not a compressed file and commonly called as a collection (which contains the contents of many files) of a single file.
Tar is the most commonly used command in Linux for creating a archive file. It saves multiple files, folders & other file formats (zip, gzip, bzip2 & tar) into a single archive file. Many of us very frequently uses three operations create, list & extract & two options file & verbose with tar to dealing the backups and restore.
Additionally we can use gzip & bzip2 commands for further compressing the tar archive. Mainly tar command used to performing backup (full and incremental) from the server by server administrator, other famous backup applications are using tar command for backup.
All the files and folders can be restore from the archive file whenever you want, every server administrator need to know the tar command and it’s usage for better backup solution.
By default tar command included into most of the distribution, so we can easily install from distribution official repository.
We are going to show you in this article, how we can use the tar command effectively for different purpose.
[Install Tar on RHEL/CentOS/Fedora] $ sudo yum install tar [Install Tar on Fedora] 22 and later] $ sudo dnf install tar [Install Tar on Debian/Linux Mint/Ubuntu] $ sudo apt-get install tar [Install Tar on openSUSE] $ sudo zypper in tar [Install Tar on Mageia] $ sudo urpmi tar [Install Tar on Arch based distro] $ sudo pacman -S tar
Syntax : Common Syntax for tar command
Options : Commonly used options in tar command are listed below
- z : Compress the backup file with ‘gzip’ to make it into small size.
- c : Create a new backup archive
- v : verbosely list files which are processed
- p : Preserves the permissions of the files put in the archive for restoration later.
- f : following is the archive file name
- x : To extract a archive file
- t : To viewing content of archive file
- j : Archive the file with bzip2
- r : To add new file or folder in existing archive file
- W : To verify a archive file content
- p : Compress the backup file with ‘present umask’.
- C : To mention the path to extract the archive file
- wildcards : Extract the group of file from archive file
1) How to create tar Archive File
The following example, backup the entire 2daygeek directory content into 2daygeek-backup-17-Dec-2013.tar file and store the backup file at /backup/site-backup/ directory.
# tar -cvf /backup/site-backup/2daygeek-backup-17-Dec-2013.tar /home/2daygeek /home/2daygeek/ /home/2daygeek/etc/ /home/2daygeek/.bashrc /home/2daygeekc/public_html/ /home/2daygeekc/public_html/captca/CaptchaSecurityImages.php /home/2daygeekc/public_html/captca/form.php /home/2daygeekc/public_html/captca/monofont.ttf /home/2daygeekc/public_html/captca/error_log /home/2daygeekc/public_html/colorlover.php /home/2daygeekc/public_html/userfunctions.php /home/2daygeekc/public_html/.htaccess
2) To create tar.gz Archive File
The following example, backup the entire 2daygeek directory content with .gzip compressed format (It uses z option which makes the tar into small size) into 2daygeek-backup-17-Dec-2013.tar.gz file and store the backup file at /backup/site-backup/ directory.
# tar -zcvf /backup/site-backup/2daygeek-backup-17-Dec-2013.tar.gz /home/2daygeek /home/2daygeek/ /home/2daygeek/etc/ /home/2daygeek/.bashrc /home/2daygeekc/public_html/ /home/2daygeekc/public_html/captca/CaptchaSecurityImages.php /home/2daygeekc/public_html/captca/form.php /home/2daygeekc/public_html/captca/monofont.ttf /home/2daygeekc/public_html/captca/error_log /home/2daygeekc/public_html/colorlover.php /home/2daygeekc/public_html/userfunctions.php /home/2daygeekc/public_html/.htaccess
3) To create tar.bz2 Archive File
The following example, backup the entire 2daygeek directory content with bzip2 compressed format (It uses j option which makes the tar into small size. This method is much better compared to gzip compression) into 2daygeek-backup-17-Dec-2013.tar.gz file and store the backup file at /backup/site-backup/ directory.
# tar -jcvf /backup/site-backup/2daygeek-backup-17-Dec-2013.tar.bz2 /home/2daygeek /home/2daygeek/ /home/2daygeek/etc/ /home/2daygeek/.bashrc /home/2daygeekc/public_html/ /home/2daygeekc/public_html/2nd_feb usernameCheck.php /home/2daygeekc/public_html/captca/ /home/2daygeekc/public_html/captca/CaptchaSecurityImages.php /home/2daygeekc/public_html/captca/form.php /home/2daygeekc/public_html/captca/monofont.ttf /home/2daygeekc/public_html/captca/error_log /home/2daygeekc/public_html/colorlover.php /home/2daygeekc/public_html/userfunctions.php /home/2daygeekc/public_html/.htaccess
Output:
As of now, i have created three archive format tar, tar.gz & tar.bz2 and located at /backup/site-backup/. See the below output for better understanding.
Here, i can see the much different on .tar.bz2 archive format compared with others. bzip2 is the high-quality data compressor method. It typically compresses files to within 10% to 15% of the best available technique (the PPM family of statistical compressors).

13) Extract Single file from .tar archive File
For some reason, you want to extract or untar only particular file from the tar archive, use the following example and replace your file name instead of us magesh.html.
# tar -xvf 2daygeek-backup-17-Dec-2013.tar magesh.html
Output:
See below magesh.html file has been extracted from tar archive and stored in the same location.
# ll -h total 81M drwxr-xr-x 2 root root 4.0K Dec 17 07:22 ./ drwxr-xr-x 3 root root 4.0K Dec 17 05:28 ../ -rw-r--r-- 1 root root 58M Dec 17 06:33 2daygeek-backup-17-Dec-2013.tar -rw-r--r-- 1 root root 7.4M Dec 17 05:57 2daygeek-backup-17-Dec-2013.tar.bz2 -rw-r--r-- 1 root root 8.3M Dec 17 05:48 2daygeek-backup-17-Dec-2013.tar.gz -rw-r--r-- 1 root root 7.4M Dec 17 06:09 2daygeek-backup-17-Dec-2013.tbz -rw-r--r-- 1 magesh magesh 53 Dec 17 06:29 magesh.html
14) Extract Single file from the sub-directory of tar archive File
The same way, you want to extract or untar only particular file from the tar archive, use the following example and replace your file name instead of us index.html.
# tar --extract --file=2daygeek-backup-17-Dec-2013.tar /home/2daygeek/tmp/webalizerftp/index.html
15) Extract Multiple file from tar archive File
Alternatively we can extract or untar more then one files from the tar archive. use the following example and replace your file name instead of us "magesh.html" "ramesh.html".
The below example will be extract the magesh.html & ramesh.html file from the .tar archive file.
# tar -xvf 2daygeek-backup-17-Dec-2013.tar "magesh.html" "ramesh.html" magesh.html ramesh.html
Output:
See below magesh.html & ramesh.html file has been extracted from tar archive and stored in the same location.
# ll -h total 81M drwxr-xr-x 2 root root 4.0K Dec 17 08:35 ./ drwxr-xr-x 3 root root 4.0K Dec 17 05:28 ../ -rw-r--r-- 1 root root 58M Dec 17 08:33 2daygeek-backup-17-Dec-2013.tar -rw-r--r-- 1 root root 7.4M Dec 17 05:57 2daygeek-backup-17-Dec-2013.tar.bz2 -rw-r--r-- 1 root root 8.3M Dec 17 05:48 2daygeek-backup-17-Dec-2013.tar.gz -rw-r--r-- 1 root root 7.4M Dec 17 06:09 2daygeek-backup-17-Dec-2013.tbz -rw-r--r-- 1 magesh magesh 53 Dec 17 06:29 magesh.html -rw-r--r-- 1 magesh magesh 17 Dec 17 08:32 ramesh.html
16) Extract Group of Files using Wildcard
For some special requirement, you want to extract or untar group of files from the tar archive, use the following example and replace required file extension instead of us .html.
In below example, we are going to extract group of file which is matched with the pattern .html from tar archive.
# tar -xvf 2daygeek-backup-17-Dec-2013.tar --wildcards '*.html' home/2daygeekc/public_html/37.99.html home/2daygeekc/public_html/57.99.html home/2daygeek/tmp/analog/11.html home/2daygeek/tmp/analog/5.html home/2daygeek/tmp/analog/12.html home/2daygeek/tmp/analog/9.html home/2daygeek/tmp/analog/10.html magesh.html ramesh.html
17) To create tar.gz Archive File and Exclude particular directory
We can exclude any directory, if we don’t want to take backup (like, if it’s holding video files). Mention the particular directory which you want to exclude with help of --exclude option and replace yours instead of us /home/2daygeek/demo then add required info too.
The below example, we are going to exclude the entire demo directory then archive rest of the files and folders.
# tar --exclude=’/home/2daygeek/demo’ -zcvpf /backup/site-backup/2daygeek-backup-17-Dec-2013.tar.gz /home/2daygeek /home/2daygeek/ /home/2daygeek/etc/ /home/2daygeek/.bashrc /home/2daygeekc/public_html/ /home/2daygeekc/public_html/2nd_feb usernameCheck.php /home/2daygeekc/public_html/captca/ /home/2daygeekc/public_html/captca/CaptchaSecurityImages.php /home/2daygeekc/public_html/captca/form.php /home/2daygeekc/public_html/captca/monofont.ttf /home/2daygeekc/public_html/captca/error_log /home/2daygeekc/public_html/colorlover.php /home/2daygeekc/public_html/userfunctions.php /home/2daygeekc/public_html/.htaccess
18) To create tar.gz Archive File and Exclude group of files
Alternatively, we can exclude group of files from any directory, if we don’t want to take backup like .mp3 & .avi files.
