Summary

  • Add automatic_backup_retention_days parameter to FSx OpenZFS component resource
  • Set retention to 30 days for both MULTI_AZ and SINGLE_AZ deployments
  • Previously defaulted to 0 (disabled), making daily_automatic_backup_start_time ineffective

Test plan

  • Deploy to a test cluster and verify FSx backup settings in AWS console
  • Confirm existing deployments update without replacement on next ptd ensure

The FSx OpenZFS file systems were created without automatic_backup_retention_days
set, defaulting to 0 (disabled). This meant daily_automatic_backup_start_time
had no effect.

Set automatic_backup_retention_days=30 for both MULTI_AZ and SINGLE_AZ
deployments to enable automatic backups.
