ECS auto snapshot policy timepoints configured reasonably

ID: rule:aliyun:ecs-snapshot-policy-timepoints-check
Severity: medium

Description

The snapshot creation timepoints in the auto snapshot policy are within the specified time range, considered compliant. Creating snapshots temporarily reduces block storage I/O performance, with performance differences generally within 10%, causing brief slowdowns. It is recommended to select timepoints that avoid business peak hours.

Reason for Violation

Auto snapshot policy timepoints may not be configured to avoid business peak hours

Recommendation

Configure snapshot creation timepoints during off-peak hours (e.g., 2:00-6:00 AM) to minimize impact on business operations
