Mirror backupĪ mirror backup (also known as an image backup or system image) is a complete copy of the entire system, including the operating system, applications, and all data.

Types of data backup in computer full#

However, to restore a differential backup, you need the full backup and the last differential backup. Differential backups are faster than full backups and require less storage space than incremental backups. However, compared to incremental backup, here not only the last incremental backup is backed up, but all changes since the last full backup. Differential backupĪ differential backup backs up all data that has been changed or added since the last full backup. However, to restore an incremental backup, you need the full backup and all incremental backups created since then. Incremental backups are faster and use less disk space than full backups because only changed or new data is backed up. In other words, only the changes that have been made since the last backup are backed up.

Incremental backup backs up only the data that has been changed or newly added since the last backup. Full backups are very time-consuming and require a lot of disk space, but they are the easiest type of backup to restore data. It backs up all data in a single backup operation, whether or not it has changed since the last backup.

Full backupĪ full backup (also known as a full backup) is a backup copy of all data that resides on a system. In the following we describe the different backup types. There are different backup types such as full backup, incremental backup, differential backup and mirror backup. The variety of backup methods: from full to incremental to differential and mirror backup.
