V18.3.0
The backup and recovery module has been migrated to the backup platform. This update ensures full compatibility with existing features while introducing a series of new features to enhance user experience and system performance:
Long-term backup policy: Supports flexible periodic backup policies, allowing users to set retention periods for backup sets according to their needs, with a maximum duration of up to 20 years (supports granular configuration by year, month, or quarter).
Backup schedule viewing: Users can conveniently view backup schedules and the next backup time, ensuring the timeliness of backup operations.
Backup overview feature: Added a backup overview feature that displays backup space usage and categorizes backup statistics by backup set type and backup method.
Backup configuration history: Supports viewing historical records of backup settings and allows rollback operations, enhancing management flexibility.
Backup list filtering and sorting: Users can filter and sort data backup lists and log backup lists, facilitating quick access to the required information.
Log continuity check: Added the log continuity check feature to ensure the integrity and consistency of backup data.
Metadata and storage pool bidirectional cross-verification: Supports bidirectional cross-verification between metadata and storage pools to enhance the accuracy of data management.
Storage pool allocation mechanism: Supports three storage pool allocation distribution mechanisms, including least instance references, lowest QPS per storage pool, and instance Hash, to optimize storage resource utilization.
Backup set cleanup model: Introduces a three-layer cleanup model for backup sets, including logical cleanup, physical cleanup, and metadata cleanup, to ensure efficient management of backup data.
