Why each option
Differential is a recognized and widely used backup strategy; the other three choices are not valid backup strategy classifications. This question tests familiarity with standard backup terminology.
A differential backup captures all data that has changed since the last full backup, growing cumulatively until the next full backup cycle runs. It balances storage use and restore speed - recovery requires only the most recent full backup plus the single latest differential set, making it faster to restore than incremental strategies while using less storage than repeated full backups.
'Integrational' is not a defined or recognized term in backup strategy taxonomy in any standard IT framework.
'Recursive' describes a method of directory traversal or algorithmic repetition and is not a classification of backup strategy.
'Supplemental' is not a standard backup strategy term; recognized types include full, incremental, and differential.
