Which of the following best describes this backup plan?

A DBA is reviewing the following logs to determine the current data backup plan for a primary data server:

Which of the following best describes this backup plan?
A . Monthly full, daily differential
B . Daily differential
C . Daily full
D . Weekly full, daily incremental

Answer: D

Explanation:

The backup plan that best describes the logs is weekly full, daily incremental. This means that a full backup of the entire database is performed once a week, and then only the changes made since the last backup are backed up every day. This can be inferred from the logs by looking at the size and duration of the backups. The full backups are larger and take longer than the incremental backups, and they occur every seven days. The other backup plans do not match the pattern of the logs.
