Backup software are computer programs used to perform backup; they create supplementary exact copies of files, databases or entire computers. These programs may later use the supplementary copies to restore the original contents in the event of data loss.


There are several features of backup software that make it more effective in backing up data.

Volumes :

Voluming allows the ability to compress and split backup data into separate parts for storage on smaller, removable media such as CDs. It was often used because CDs were easy to transport off-site and inexpensive compared to hard drives or servers. However, the recent increase in hard drive capacity and decrease in drive cost has made voluming a far less popular solution. The introduction of small, portable, durable USB drives, and the increase in broadband capacity has provided easier and more secure methods of transporting backup data off-site.

Data compression

Since hard drive space has cost, compressing the data will reduce the size allowing for less drive space to be used to save money.

Remote backup

Several factors have contributed to a surge in the use of remote or offsite backup of data to geographically distant sites.

  • The rapid growth of data and its importance to business.
  • The rapid adoption of high-speed broadband internet.
  • The falling price of disk drive technology.
  • The rise of risks such as hackers, natural disasters, fires, damage by power outages, malware attacks, terrorist attacks, hardware failure.

These structural changes present opportunities for young startups, which are serving this growing market with next-generation backup technologies that automatically back up data to offsite data centers (sometimes called vaults) via the Internet. Many banks, stock exchanges, and other large institutions often do this to ensure data integrity.
