System Backup

I need to backup my system, i mean entire system, not just a restore point. And i need to have this scheduled to be done at least once a week. I need something that will take an entire copy of my harddrive so that if my system crashes i can just load a copy and be back up and running. What programs are excellent in producing backups of this nature? I am thinking of buying a tape drive for these backup, does anyone have other ideas.

Thanks in advance.

Have a look at Symantec Ghost or Acronis True Image.

I would suggest Symantec Livestate Recovery:
Server and Desktop version. try full working evaluation:
