Amazon Elasticsearch Service 提供 14 天免費的 hourly snapshot:「Amazon Elasticsearch Service increases data protection with automated hourly snapshots at no extra charge」。
Amazon Elasticsearch Service has increased its snapshot frequency from daily to hourly, providing more granular recovery points. If you need to restore your cluster, you now have numerous, recent snapshots to choose from. These automated snapshots are retained for 14 days at no extra charge.
不過這是 5.3+ 版本才有,舊版只有 daily:
- For domains running Elasticsearch 5.3 and later, Amazon ES takes hourly automated snapshots and retains up to 336 of them for 14 days.
- For domains running Elasticsearch 5.1 and earlier, Amazon ES takes daily automated snapshots (during the hour you specify) and retains up to 14 of them for 30 days.
In both cases, the service stores the snapshots in a preconfigured Amazon S3 bucket at no additional charge. You can use these automated snapshots to restore domains.
