Which type of backup is typically the fastest in PowerProtect Data Manager?

Question

Options

• AFull backup
• BIncremental backup
• CDifferential backup
• DMirror backup

• A
  2% (1)
• B
  91% (51)
• C
  2% (1)
• D
  5% (3)

Explanation

Incremental backup is the fastest because it only captures data that has changed since the last backup of any kind (full or incremental), making the data set as small as possible. Full backup (A) is the slowest - it copies everything every time, regardless of what changed. Differential backup (C) copies all changes since the last full backup, so it grows larger over time and is slower than incremental but faster than full. Mirror backup (D) is essentially a real-time clone of the source, which is resource-intensive and not the fastest in terms of backup job execution.

Memory tip: Think of the "I" in Incremental as "I only grab the little bits" - it has the smallest scope of any backup type, which is exactly why it's fastest.
