Which backup type does PowerProtect Data Manager use to capture only the changes since the last full backup?

Question

Options

• AFull backup
• BIncremental backup
• CDifferential backup
• DSnapshot backup

• A
  2% (1)
• B
  6% (3)
• C
  89% (47)
• D
  4% (2)

Explanation

Differential backup captures all changes made since the last full backup - not since the last backup of any type - making option C correct for this scenario. Option A (Full backup) is wrong because it copies all data every time, not just changes. Option B (Incremental backup) is the close distractor: it captures changes since the last backup of any kind (full or incremental), so each incremental is smaller but restore requires chaining multiple backups together. Option D (Snapshot backup) creates a point-in-time copy of data at the block/volume level and is a separate mechanism, not defined by its relationship to a full backup.

Memory tip: Think "Differential = Delta from Full" - the D in both words links them. Incremental links to itself (last backup), while Differential always looks back to the Full.
