Read the first 7 Backup and Disaster Recovery flashcards as text

  1. Which backup strategy copies only files that have changed since the last FULL backup, regardless of whether a previous incremental backup was taken?

    Answer: Differential backup

    A differential backup copies all data changed since the last full backup, making it independent of other differential backups.

  2. What is the primary purpose of a hot site in disaster recovery planning?

    Answer: To provide a fully operational duplicate environment with minimal failover time

    A hot site is a fully equipped, always-on duplicate facility that allows near-immediate failover during a disaster.

  3. An administrator needs to restore a single deleted file from three weeks ago. The organization uses weekly full and daily incremental backups. What is the minimum number of backup sets needed?

    Answer: Up to 3 (the full plus each incremental up to the deletion date)

    With incrementals, you need the last full backup plus every incremental from that point up to the day before deletion.

  4. What does the term 'journaling' refer to in the context of database backup and recovery?

    Answer: Recording all transactions so the database can be replayed to a consistent state

    Database journaling records every transaction, enabling point-in-time recovery by replaying or rolling back those transactions.

  5. Which RAID level provides disk striping with parity distributed across all drives, offering both performance and fault tolerance?

    Answer: RAID 5

    RAID 5 stripes data and distributes parity across all member drives, tolerating a single drive failure.

  6. A company's DR plan states that systems must be fully operational within 4 hours of a declared disaster. Which metric does this define?

    Answer: Recovery Time Objective (RTO)

    RTO defines the maximum acceptable time to restore systems and resume normal operations after a disaster.

  7. What is a 'bare-metal restore'?

    Answer: Recovering a complete system including OS, applications, and data to new or wiped hardware

    Bare-metal restore rebuilds an entire system from scratch onto hardware that has no existing OS or data.
