Which of the following is true about backups?

• A. Backups should be created as a precaution against damage or loss of the original data
• B. Backups should be created on a regular basis
• C. Backups should be created only before loading new software
• D. Both A and B

Answer: (D)

Backups act as safeguards against data loss. They provide a recoverable copy if the original data is damaged, corrupted, accidentally deleted, or if hardware or software failures occur. Creating backups on a regular schedule keeps copies up to date, so you can restore to a recent version with minimal loss. Backing up only before loading new software is too narrow a practice; while you should back up before significant changes, you also need ongoing routine backups to protect everyday data. A solid approach combines precaution with regularity, and using a strategy like keeping multiple copies on different media and, ideally, offsite, helps ensure you can recover in various scenarios.
