![]() Slower to back up compared to incremental backups.Takes up more space than incremental backups.Quicker to restore as it only has two backup sets.Faster to back up compared to full backups.This provides better data protection and a valid disaster recovery solution. As they only consist of two backup sets, their recovery time is much better. In this setup, the backup sets do not rely on each other, but rather on the full backup from which they originated. Differential backups only save changes made since the last full backup while incremental backups save all changes made since the last backup. However, it differs in the way these changes are saved. Risk of failed recovery if there is damage to a segment in the backup chain.Ī differential backup is similar to incremental as it relies on a full backup, followed by saving only the changes made on that source volume.Smaller backups take up less storage space.Having a larger number of backup sets also affects recovery time. Suggesting that any damage or loss on one of the sets may inflict incomplete data recovery. The downside is that each incremental backup depends on the one before it. Since the sets are smaller compared to the volume set, they take less time to back up. This method is more efficient as it takes up less space on the system. Next, on Wednesday, it will back up any changes made since Tuesday, and so on. Therefore, on Tuesday, it creates copies of any changes that have been made since Monday. ![]() Therefore, it exclusively saves data that has been modified or added to the existing data volume.Įxample: An administrator can arrange a full backup of the data set on Monday and then incremental backups between Tuesday and Friday. This setup is designed only to back up data that has changed since the previous backup.
