A Backup software is not to be used only for emergencies. Its good practice to backup you data regularly. A backup can be considered an insurance for your data. Computer data can be easily lost: your hard drive can suddenly fail, a virus can wipe files from your computer or your computer/laptop may get stolen. You're protected against such distasters only if you have a backup of your files.
When an incident happens it's a simple matter of restoring that data and you are back in business.
I tried it out an found that Titan Backup software is an easy-to-use and complete solution.
Its wizard-driven interface helps you backup all your important documents, photos, music, emails and program settings,
including your Windows settings, Registry, etc. For a list of its complete features go

Titan Backup 2.3 is a very recent release and is shareware.
But its earlier version will soon be offered to members of WinVistaClub FREE.
Stay tuned.
