How to Backup Home Folder on Linux With Tar
Subscribe to 22halomedia YouTube Channel
Introduction
Creating regular backups is always a wise decision and considered best practice. In this guide you will learn how to backup your home directory on Linux using the tar utility. Your home directory is where all your user’s files are. Typically the most important data will be found here.
Go to Your Home Directory
Use the below command to go to your home directory:
```
cd ~
```
Create Backup Directory
Before backing up your home directory you should have a good idea where you want to store your archived files. For the purposes of this guide, we will create a Backups directory in the home directory.
Make the Backups directory:
```
mkdir ~/Backups
```
Print Absolute Path of Home Directory
The absolute path of the home directory in this guide is /home/me.
Use the following command to print your home directory:
```
pwd
```
Backup Your Home Directory
Backup your home directory now that you know its absolute path:
```
tar -czxf /home/Backups/backup.tar.gz /home/me
```
Tar Flags Explained
The -c flag tells tar to create a new archive.
The -z flag directs tar to use gzip, which has the extension tar.gz
The -v flag instructs tar to use verbose output. This means when tar is ran it will output each file added to the archive to the terminal.
The -f flag specifies the file to use for the archive.
Conclusion
It is important to take regular backups to prevent data loss. Additionally, its a good idea to store these backups in several different places. For instance, an external drive and cloud storage (rather than just one).
