Types of Backups
- Full Backup: Full backup ensures that all data is preserved. It is time-consuming and requires significant storage space. Full backups are commonly done less often because they consume a lot of resources.
- Incremental Backup: Incremental backup is a type of backup that only backs up data in the last session or the one that was already done on the computer. It is more efficient in terms of storage space and speed, but it needs many other backups to perfectly restore all the data.
- Differential Backup: A differential backup copies all data that has changed since the last full backup. Unlike incremental backups, differential backups do not depend on each other, hence they can be restored faster, however,, they require more storage compared to incremental backups over time.
- Mirror Backup: A mirror backup is an exact copy of the source data at a given point in time. Mirror backups, which do not compress the data, are faster to make compared to other backup forms but need more storage space. Although they are good for immediate recovery purposes, they lack historical versions of the data.
- Cloud Backup: Storing data on remote servers managed by a third-party service provider is what is termed as cloud backup. Also, this method provides scalability, automated backups as well as offsite storage hence it is appealing to numerous users and enterprises. Depending on the service plan chosen, cloud backups are usually complete, and incremental because of differential.
What is Backup?
The process of duplication of data in order to achieve data preservation in case of loss is known as backup. These duplicates can be used in place of the first data copy if it is destroyed, damaged, or missing. It is aimed at preventing data loss that may be caused by hardware failure, software breakdown, human-made mistakes, and natural disasters including cybercrime.
