Backup Home Directories in Linux

Q. I would like to Backup all directories in /home to /dev/st0 tape drive. How do I use script to automate task and what commands do I need to use?

A. Use tar command to backup /home directory. The GNU version of the tar archiving utility included with all Linux distributions. Following tar command also works with Solaris/HP-UX UNIX and FreeBSD/*BSD oses.
For example tar command to backup /home should be as follows:
 

# tar -czf /dev/st0 /home


Where,

1. /dev/st0 : Linux SCSI Tape device name
2. /home : Home directory name
