Back up your data on each computer used in your business. Your data includes (but is not limited to) word processing documents, electronic spreadsheets, databases, financial files, human resources files, accounts receivable/payable files, and other information used in or generated by your business. It is necessary to back up your data because computers die, hard disks fail, employees make mistakes, and malicious programs can destroy data on computers. Without data backups, you can easily get into a situation where you have to recreate your business data from paper copies and other manual files. .
