säilituskoopiast

Säilituskoopia, commonly referred to as backup in English, is a process of copying and archiving data so that it may be restored in the event of data loss. Data loss can occur due to hardware failure, human error, corruption, or natural disaster. Säilituskoopiad are crucial for ensuring business continuity and data recovery.

There are various types of säilituskoopiad, including full backups, incremental backups, and differential backups. A full backup copies all data. An incremental backup copies only the data that has changed since the last backup, regardless of whether it was a full or incremental backup. A differential backup copies only the data that has changed since the last full backup.

Säilituskoopiad can be stored in different locations, such as on-site, off-site, or in the cloud. On-site storage involves keeping copies of data within the same physical location as the original data. Off-site storage involves storing copies in a different geographical location to protect against site-specific disasters. Cloud storage utilizes remote servers maintained by a third-party provider.

The frequency of säilituskoopiad depends on the criticality of the data and the acceptable amount of data loss. Regular testing of säilituskoopiad is essential to verify their integrity and ensure that data can be successfully restored when needed. Implementing a robust säilituskoopia strategy is a fundamental aspect of data management and disaster recovery planning.
