Data Backups - CompTIA Security +
Hola!
this topic is for me a bit enjoying, again one of those topics that resonates, I had experience and then when looking at say it out loud well...
Data Backups
A data backup involves creating duplicate copies of digital information to protect against data loss, corruption, or unavailability. It safeguards data from accidental deletion or system failures.
Types of Backups (Based on Storage Location):
- Onsite Backup: Storing data copies in the same location as the original data. These are convenient but vulnerable to physical disasters.
- Offsite Backup: Storing data copies in a geographically separate location. These protect against physical disasters that could affect the primary location.
Backup Frequency:
The frequency of backups is determined by the organization's Recovery Point Objective (RPO). The RPO (ohh dear "risk management" ...(・_・;) ) ensures that the backup plan will maintain the required amount of data to keep any data loss below the organization's RPO threshold. Considerations for frequency include:
- Data change rate
- Resource allocation
- Organizational needs
Related Concepts:
- Snapshots: Point-in-time copies of data that capture a consistent state. They only record changes since the previous snapshot, reducing storage requirements. They are valuable for systems where data consistency is critical, such as databases and file servers.
- Data Recovery: The process of restoring access to data in the event of loss or system failure. A well-defined and tested recovery plan is essential.
- Replication: Copying data in real-time or near real-time to maintain data continuity. It ensures seamless data continuity and is suitable for high-availability environments.
- Journaling: Maintaining a detailed log of data changes over time. It allows for granular data recovery, maintains an audit trail, and ensures data integrity and compliance.
Importance in Cyber Resilience and Recovery:
Backups are important elements for cyber resilience and recovery in security architecture.
- Cyber Resilience: The ability to provide outcomes despite adverse cyber events.
- Recovery: Assesses the system's ability to restore normal operation after a disruptive event.
Ok i HOPE next time my brain can reply 🧠 fluently as it follows:
Backups are a key part of a Business Continuity and Disaster Recovery Plan (BC/DR Plan), which ensures smooth business operations during unforeseen events. A Disaster Recovery Plan (DRP) specifically focuses on IT systems and data recovery after disasters and is a subset of the Business Continuity Plan (BC Plan).
An hopefully everyone will be happy enough to continue Business As usual. Hope my notes helps you for more just click here
Adiós! 👋
