Managing Manual Backups

To ensure data reliability, you can manually back up GeminiDB HBase instances in the Available status. If a database or table is deleted, maliciously or accidentally, backups can help recover your data.

Usage Notes

  • Manual backups are full backups.
  • Backup files are saved as packages in OBS buckets. Uploading backup files and reading service data both consume bandwidth, so the upload bandwidth of OBS is limited. The upload bandwidth of a single node ranges from 20 MB/s to 70 MB/s.

    For better performance, you need to specify appropriate nodes for an instance and take into account the bandwidth for uploading backups.

  • The CPU usage may increase 5% to 15% because uploading backups consumes CPU resources.
  • While backups are uploaded, the memory usage does not increase significantly. Generally, the memory usage is about 300 MB. How much memory usage actually increases depends on the instance data volume. The increased memory mainly caches data during backup upload and service read. After the backup upload is complete, the memory recovers.
  • Manual backups are charged for instances with cloud native storage during OBT.
