- A
That the backup files exist in storage.
Why wrong: File existence alone does not prove the backup can be used to restore business operations. A backup must also be restorable and usable.
- B
That the data can be restored and is usable after recovery.
The real purpose of a backup is successful recovery. During testing, the team should verify that the data restores correctly and that applications or users can actually use it afterward. This confirms the backup supports business continuity and is not merely sitting in storage as an unreadable copy.
- C
That the backup system uses encryption.
Why wrong: Encryption is important for protection, but it does not prove the backup will restore correctly during an outage. Recoverability is the key test here.
- D
That the backup is stored on tape instead of disk.
Why wrong: The storage medium is not the main concern in a restore test. What matters is whether the backup can be successfully recovered and used.
Quick Answer
The answer is that the most important thing to confirm about a backup is that the data can be restored and is usable after recovery. This is because backup validation goes far beyond simply checking that backup files exist; it requires a full restore test to verify data integrity and completeness, ensuring the backup is free from corruption and that the restoration process itself functions correctly. On the Security+ SY0-701 exam, this concept tests your understanding of disaster recovery principles, specifically how a valid backup directly supports meeting the recovery point objective (RPO) and recovery time objective (RTO). A common trap is assuming that a successful backup log or file listing is sufficient, when in reality only a successful restore proves the backup is viable. Remember the memory tip: “Backup is a guess, restore is the proof.”

Correct answer & explanation
That the data can be restored and is usable after recovery.
The most important thing to confirm about a backup during a disaster recovery test is that the data can be restored and is usable after recovery. This validates the integrity and completeness of the backup, ensuring that the recovery point objective (RPO) and recovery time objective (RTO) can be met. Simply verifying that backup files exist does not guarantee they are not corrupted or that the restoration process will succeed, which is why a full restore test is critical.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
That the backup files exist in storage.
Why it's wrong here
File existence alone does not prove the backup can be used to restore business operations. A backup must also be restorable and usable.
- ✓
That the data can be restored and is usable after recovery.
Why this is correct
The real purpose of a backup is successful recovery. During testing, the team should verify that the data restores correctly and that applications or users can actually use it afterward. This confirms the backup supports business continuity and is not merely sitting in storage as an unreadable copy.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse backup existence with backup usability, assuming that if the backup file is present and encrypted, it must be restorable, but CompTIA emphasizes that only a successful restore test confirms recoverability.
Detailed technical explanation
How to think about this question
A proper disaster recovery test should include a full restore of the backup to a separate environment, followed by application-level validation (e.g., running database consistency checks like DBCC CHECKDB for SQL Server or fsck for file systems). This ensures that not only are the files readable, but the data is logically consistent and the application can function correctly, which is the true measure of a successful backup. In real-world scenarios, a backup that appears valid but fails during a restore due to silent corruption or missing dependencies can lead to extended downtime and data loss.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A developer is choosing between AES-256 (symmetric) and RSA-2048 (asymmetric) for encrypting a large file that will be sent to a partner. Symmetric encryption is fast but requires key exchange; asymmetric is slower but solves the key distribution problem. A hybrid approach — encrypt the file with AES, encrypt the AES key with RSA — is standard. Questions like this test whether you understand when each approach applies.
