Data Backup

A data backup is the result of copying or archiving files and folders for the purpose of being able to restore them in case of data loss.

Data loss can be caused by many things ranging from computer viruses to hardware failures to file corruption to fire, flood, or theft (etc). If you are responsible for business data, a loss may involve critical financial, customer, and company data. If the data is on a personal computer, you could lose financial data and other key files, pictures, music, etc that would be hard to replace.

In the early days of personal computers (PC), the common data backup method was to download data from a computer’s hard drive onto a set of small floppy disks, which were stored in physical containers. Since then, the emergence of solid-state technologies, wireless systems and other innovations have led to situations where IT managers have the option of backing up data remotely or downloading huge amounts of data into small portable devices. Cloud services and related options facilitate easy remote data storage, so that data is secure if an entire facility or location is compromised, while RAID, or mirror, technologies provide automated backup options.
