Data collection and Input

Backup

I will use Databases so I can back up my data, as it is small businesses I will Use only one hard drive on 500GB Memory to back up. The idea is that the company would have all information saved on one hard drive ..the hard drive will also operate 24hours a day. And the company will Install Antivirus Program as it reduces the risks of Data-loses. And in addition to that the company will Install Norton Ghost As it will help to prevent data loses in system crashes.
