Which of the following backup technique is the most space efficient?

  By GK Planet Team       Monday, 22 January 2018
Q. Which of the following backup technique is the most space efficient?

(A) Full backup
(B) Differential backup
(C) Incremental backup
(D) None of these

Answer: Incremental backup

The term backup has become synonymous with data protection over the past several decades and may be accomplished via several methods. Backup software applications have been developed to reduce the complexity of performing backup and recovery operations.
Backup applications have long offered several types of backup operations. The most common backup types are a full backup, incremental backup and differential backup. Other backup types include synthetic full backups, mirroring, reverse incremental and continuous data protection (CDP).
An incremental backup is one in which successive copies of the data contain only that portion that has changed since the preceding backup copy was made. When a full recovery is needed, the restoration process would need the last full backup plus all the incremental backups until the point of restoration.
