Data backup is archiving or copying folders and files for the purpose of restoring them when data loss occurs. Data loss can be as a result of many things such as hardware failures, file corruption, computer viruses among others. For people responsible for enterprise data, a loss can involve critical customer, financial, and company data. When data is on a personal computer, one can lose key files such as music, pictures, movies and many others.
Data to Back Up
You should back up all data or work that cannot be replaced with ease. Such data includes word processing documents, databases, spreadsheets, personal files, and customer data. One should, however, avoid backing up system or program folders. Programs need to be reinstalled before running them while system folders are restored from the operating system install disc. For any downloaded applications, their files should be saved for re-installation when needed.
Frequency of Running Backups
The frequency of backing up your data depends on how often you alter it. Business data, for example changes every now and then and should be backed up daily or hourly. Data that changes after few days may require monthly or weekly backup. WinZip Job Wizard, for example, allows one to schedule backups and run them automatically. One does not need to remember to do it manually because they backup at specified times. Follow this link for more information.
Methods of Backing up Data
