An administrator wants to minimize the amount of time needed to perform backups during the week. It is also acceptable to the administrator for restoration to take an extended time frame. Which of…

Question

Options

• AFull backups on the weekend and incremental during the week
• BFull backups on the weekend and full backups every day
• CIncremental backups on the weekend and differential backups every day
• DDifferential backups on the weekend and full backups every day

• A
  74% (14)
• B
  5% (1)
• C
  16% (3)
• D
  5% (1)

Explanation

The key trade-off in backup strategies is between backup speed and restore speed. Incremental backups capture only data changed since the most recent backup of any type (full or incremental), making each daily backup as small and fast as possible - directly satisfying the requirement to minimize weekly backup time. The cost is that restoration requires the full backup plus every incremental set applied in sequence, which takes the longest time - acceptable per the scenario. Option B (full backups daily) takes the most time to back up. Option C (incremental on weekend, differential daily) is reversed; differentials grow larger each day relative to incrementals. Option D (differential on weekend, full daily) requires the longest daily backup time because full backups capture everything each day.
