What is a data backup?
Backups are copies of computer data, such as contracts, drawings, recipes, forecasts, quality data, compensation plans, and other contents stored on a hard drive. The verb backup means to make a copy of a computer file or other data to protect against accidental loss or corruption.
Types of Backups
There are many different types of backups, each serving their purpose.
- Standard backups focus on creating copies of files from one or multiple systems across a network.
- System backups are complete copies of a system, including the settings and preferences of the operating system. Depending on the need or capabilities of a business, many perform scheduled backups of files, while having system backups for baseline configurations when new machines join the network.
- Incremental and differential backups focus on the changes between files on a system but are different in the focus of the changes. A differential backup will only back up any files that have changed since the last backup. Incremental backups, on the other hand, only backs up the changed data found in files. Between these two types of backups, incremental backups are considerably faster than a differential backup.
