To overcome the disadvantages of full backups, the concept of Incremental backups were introduced. You can carry this type of backup on a weekly/monthly basis. In this scenario, the backup and restore process will take a long time to complete and you will also need a larger storage resource. Initially, it is 2 TB and on the next day, if I add files or make changes, this will lead to the addition of 0.5 TB to the initial 2TB so now I have 2.5 TB. Here, 2TB of data can have changes happening in it on a daily basis. I can understand your question, if it is 2TB of backup data and storage is 10 TB then I must have logically 5 days of full backups. If I perform a full backup on a daily basis (for 5 days), then I can store only 3 or 4 full backups. But the firms can only periodically use this back up since it is more resource consuming.Ĭonsider you want to take a backup of 2TB data and store it in a 10 TB storage device. Apart from the above-said types, there are various types such as mirror backup, reverse incremental backup and continuous backup.Ĭontinue reading to know about these 5 different types, 3 variations of it and find out which one will suit your environment.Ī full backup is a complete copy of the data you’ve configured for backup.
In the above-listed types of backup, the full, incremental and differential backups are basic types that everyone must have heard about, but the synthetic and incremental forever backups are two new types to the data backup market. In this blog, I will explain the backup types/methods and their advantages. Data backup can ensure data protection and there are different methods of data backups. Data protection has turned to be of everyone’s concern, every day there are data losses happening around the world.ĭata backup is a process of taking a copy or duplicating the data to allow recovery of the duplicated set after an event of data loss.
