+## How to Backup a specific user's home directory?
+
+Use the following command to take a backup of a user's home directory:
+
+In this example, we will backup our test user – **`'2daygeek`**'s home directory, and the output file will be saved in the ** `'/backup'`** directory.
+
+```
+# tar -zcvpf /backup/2daygeek-backup-$(date +%d-%m-%Y).tar.gz /home/2daygeek
+```
+Due to some reason, if you would like to exclude some folders from backing up, then use the following format:
+
+Note: The below example will exclude the entire ** `'demo'`** directory and archive the rest of the files and folders.
+
+```
+tar --exclude='/home/2daygeek/demo' -zcvpf /backup/2daygeek-backup-$(date +%d-%m-%Y).tar.gz /home/2daygeek
+```
+
+Similarly, if you would like to exclude some of the pattern files or group of files, then use the following format:
+
+Note: The below example will exclude the ** `'.mp3 & .avi'`** files from ** `'demo'`** directory and archive the rest of the files.
+
+```
+tar -- **exclude**={'*.mp3','*.avi'} '/home/2daygeek/ **demo**/' -zcvpf /backup/2daygeek-backup-$(date +%d-%m-%Y).tar.gz /home/2daygeek
+```
+
+## How to Backup a single user's home directory using shell script?
+
+This shell script allows you to backup the given user's home directory.
+
+To do so, add the following shell script in a file:
+
+```
+#!/bin/bash
+DATE=$(date +%d-%m-%Y)
+BACKUP_DIR="/backup"
+
+#To backup 2daygeek's home directory
+tar -zcvpf $BACKUP_DIR/$USER-$DATE.tar.gz /home/$USER
+
+#To delete files older than 10 days
+find $BACKUP_DIR/* -mtime +10 -exec rm {} \;
+```

 ## `tar` commands
 
+```bash
+tar -zcvpf /[Backup_File_Location]/[Backup_Filename] /[User's_Home_Directory_Location]
+
+z : Compress the backup file with ‘gzip’ to make it 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 later restoration.
+f : use archive file or device ARCHIVE.
+```
+
 To extract an uncompressed archive:
 `tar -xvf /path/to/foo.tar`
