Backup & Recovery in NewSQL

Backup and recovery are critical components in the management of NewSQL databases. With their ability to handle high transaction volumes and provide ACID compliance, ensuring data integrity through robust backup and recovery strategies is essential.

• Backup: The process of creating a copy of the database to protect against data loss.
• Recovery: The process of restoring the database from a backup to recover lost or corrupted data.
• Point-in-Time Recovery: The ability to restore the database to a specific moment in time.
• Incremental Backup: Backing up only the data that has changed since the last backup.
• Full Backup: Creating a complete copy of the database at a specific point in time.

NewSQL databases offer various backup strategies:

1. Full Backup: Execute a complete backup of your database.
2. Incremental Backup: Create backups that only include changes made since the last backup.
3. Snapshot Backup: Utilize filesystem snapshots for quick backups without impacting performance.

Recovery methods can vary based on the backup strategy used:

1. Full Recovery: Restore the database from the last full backup.
2. Point-in-Time Recovery: Use transaction logs to restore the database to a specific point.
3. Rolling Recovery: Apply incremental backups sequentially to reach the desired state.

• Regularly schedule backups based on data volatility.
• Test recovery procedures periodically to ensure functionality.
• Store backups in multiple locations (onsite and offsite).
• Use encryption for backup files to protect sensitive data.
• Monitor backup processes and alert for failures.
