Storage System Recovery Manager
The "System Configuration Database Recovery Manager" in QuantaStor serves the purpose of managing and recovering the system configuration database, which is crucial for maintaining the integrity and functionality of the storage system's configuration settings. The system database contains all of the configuration information for the system like hosts, users, user groups, network configuration, and replication schedules. You do not need to recover that internal database to recover volumes and network shares, those will recover automatically.
Here's why you might use it:
- Disaster Recovery: In the event of system failures, hardware malfunctions, or data corruption, the recovery manager can restore the configuration database from backups. This ensures that the storage system can quickly return to its operational state with minimal disruption.
- Configuration Integrity: The configuration database stores critical settings and information about the storage system, including network settings, storage pool configurations, and user permissions. The recovery manager helps maintain the integrity of this database by providing tools for backup and restoration.
- Backup Management: The recovery manager likely includes features for creating, managing, and scheduling backups of the configuration database. Regular backups are essential to protect against data loss and ensure that a recent, accurate version of the configuration is always available for recovery.
- System Updates and Upgrades: Before performing system updates or upgrades, administrators can use the recovery manager to create a backup of the current configuration database. This provides a safety net, allowing the system to be restored to its previous state if the update or upgrade encounters issues.
- Audit and Compliance: For organizations that need to comply with regulatory requirements, having a reliable method to backup and restore configuration settings can be critical. The recovery manager helps ensure that configuration data can be audited and restored in compliance with these regulations.
- Ease of Management: The recovery manager simplifies the process of managing the configuration database by providing a user-friendly interface for backup and recovery tasks. This reduces the complexity and potential for errors, making it easier for administrators to maintain the system.
- Mitigating Human Error: In cases where configuration changes are made that negatively impact the system, the recovery manager allows administrators to revert to a previous configuration state. This mitigates the impact of human error and ensures system stability.
Overall, the purpose of the "System Configuration Database Recovery Manager" in QuantaStor is to provide a robust and reliable way to manage, backup, and recover the system configuration database, ensuring the storage system's stability, integrity, and resilience against data loss or corruption.

Can I use an old version of a QuantaStor database with the latest version?
Yes, the QuantaStor core service was designed with a dynamic schema upgrade system that enables us to support upgrading from any older version to any newer version of QuantaStor.
How often is the internal database backed up?
The core service does a backup of the internal database to every storage pool every hour so that you have at least 5 backups of the internal database on every storage pool. In most cases the internal database is very compact (less than 10MB) to it uses almost no disk space in your storage pool to retain these backups.
