Nightly county payroll backups must include every change since last Sunday’s full backup, not merely changes since last night’s job. Which backup type fits?
Select an answer to reveal the explanation.
Short Explanation
Differentials keep stacking everything since the big Sunday backup, like a growing pile of receipts since payday. They are not limited to what changed since last night. That is the key contrast with incrementals.
Full Explanation
Differential backups capture all changes since the last full backup, so each nightly differential stands relative to that full rather than to the prior differential or incremental. Incremental backups typically reference the last backup of any type and therefore miss the “since last full” requirement when used alone. Understanding this distinction drives restore chain length and storage growth.
