Backup is the process of creating copies of data to protect it against loss or damage. Backups are a critical element of information security, allowing you to recover data in the event of a disaster, hacking, or physical damage to the media.
Types of backup
- Local backup. Data is copied to local storage media such as external hard disks or USB storage devices.
- Cloud backup. Data is stored in cloud services, allowing access from anywhere and automatic updates.
- Full backup. A complete copy of all data is created.
- Incremental backup. Only changes that have occurred since the last backup are copied.
Backups allow you to restore almost any data in case of disaster or destruction. Properly organized backup system allows you to quickly restore data and continue working without significant downtime.
