Managing Manual Backups

Precautions

• Manual backups are full backups.
• Backup files are saved as packages in OBS buckets. Upload of backup files and service reads both consume bandwidth, so the upload bandwidth of OBS is limited. The 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.
• The memory usage may increase by about 300 MB during the upload of backups. The increase depends on the instance's data volume. The increased memory mainly caches data during backup upload and service read. After the backup upload is complete, the memory recovers.
