Data backup strategies – UGC NET Question

Statements A, B, C and E capture key aspects of reliable backup strategies, whereas D and F are unsafe. Regular and documented backups to separate locations, along with test restorations, help institutions recover from failures or disasters. Keeping only one copy is not a backup at all, and performing backups only once a year ignores day-to-day data changes. Thus the correct set excludes D and F and includes A, B, C and E.

Option A:
Option A is incorrect because it omits A, which stresses regular backups to reduce loss, and it includes F, which wrongly suggests backups only once a year are sufficient. Therefore this set is not correct.

Option B:
Option B is incorrect because it includes F and omits C. Adding F suggests that annual backups are sufficient, which is inappropriate for dynamic institutional data. Leaving out C removes reference to documented schedules, so this option is not acceptable.

Option C:
Option C is correct because it encompasses regular backups, off-site storage, clear schedules and test restorations as a coherent strategy. It properly rejects D’s and F’s oversimplified approaches that expose data to unnecessary risk.

Option D:
Option D is incorrect because it includes F and omits B. Without B, there is no protection against local disasters, and including F implies very infrequent backups, so this combination cannot be correct.
