Scenario: A company regularly performs backups of its DB2 database using the EXPORT utility. However, the size of the backups has become increasingly large, impacting storage and performance. What strategies could the company implement to address this issue?

  • Archive Logs
  • Implement Compression
  • Increase Buffer Pool Size
  • Use Parallelism
Implementing compression is an effective strategy to address the issue of large backup sizes when using the EXPORT utility. By enabling compression during the export process, the company can significantly reduce the size of the backup files, thereby saving storage space and improving overall performance. Compression techniques such as zlib or gzip can be applied to the exported data to achieve compression ratios that balance between space savings and processing overhead.
