An administrator is designing and implementing a server backup system that minimizes the capacity of storage used. Which of the following is the best backup approach to use in conjunction with…

Differential backups store all changes since the last full backup, meaning they grow in size with each passing day until a new full backup is performed, thus not minimizing storage capacity as effectively as incremental backups.

Open file backup refers to the ability to back up files that are currently in use, not a specific backup strategy that minimizes storage capacity.

Archive backups are typically used for long-term storage of inactive data and do not describe a strategy for minimizing daily operational backup storage capacity.

Incremental backups capture only the data that has changed since the last any type of backup (full or incremental), making them the smallest in size and thus minimizing storage capacity for daily changes. When combined with synthetic full backups, incremental backups are highly efficient because the synthetic full can be generated quickly from the last full and the subsequent incremental changes, without requiring a resource-intensive new full backup from the source.
