Backup software is a computer program used to perform a complete back up of a file, data, database, system or server. The back up software enables you to make an exact duplicate of everything contained on the original source. This software must also be used to perform a recovery of the data or system in the event of a disaster.

Key features of backup software
There are several features of backup software that make it more effective in backing up data.
Volumes
main: Volume (compression) 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
main: 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
main: 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, hurricanes, viruses, hardware failure.
These structural changes present opportunities for young startups, which are serving this growing market with next-generation backup technologies that automatically backup 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.
Access to open files
main: File locking Many backup solutions offer a plug-in for access to exclusive, in use, and locked files.
Incremental backups
main: Backup rotation scheme Backup solutions generally support incremental backups in addition to full backups, so only material that is newer or changed compared to the backed up data is actually backed up, in order to dramatically increase the speed of the backup process.
Schedules
main: Job scheduler Backup schedules are usually supported to reduce maintenance of the backup tool and increase the reliability of the backups.
Encryption
main: Encryption To prevent data theft some backup software offers cryptography features to protect the backup.
