Frequently Asked Questions (Database Administration & Maintenance)
Why is access control auditing critical for database compliance?
Regulations like POPIA and GDPR mandate that personal data access is restricted exclusively to authorized personnel with logged audit trails.
What is Point-In-Time Recovery (PITR)?
PITR uses transaction log backups to restore a database to an exact microsecond timestamp right before a data corruption event occurred.
How do you protect database backups at rest?
Backup files must be encrypted using AES-256 encryption before being transferred over the network or saved to storage media.
