Protected Scaling Instance Backup and Recovery

Scenario

Mark mission-critical ECS instances in an Auto Scaling group as protected from termination or place them in standby, then configure automatic snapshot policies and snapshot-consistent groups for those specific instances so their data survives scaling events and can be restored if needed.

How the products combine

1. ess · ess-manage-instances — Auto Scaling — Manage instances within a scaling group

See ess/ess-manage-instances.

2. ecs · ecs-manage-recovery — ECS — Manage data protection and recovery for ECS

See ecs/ecs-manage-recovery.

Typical questions

• protect scaling instance and back up its disks
• standby instance then snapshot
• ESS实例保护并配置快照策略
• prevent termination and enable auto snapshots for scaling group
• restore protected instance disk from snapshot
• scaling group关键实例数据保护
• put instance in standby before backup
• manage instance lifecycle with snapshot policy

Q: How do I protect scaling instances and back up their disks? A: Mark mission-critical ECS instances in an Auto Scaling group as protected from termination or place them in standby, then configure automatic snapshot policies and snapshot-consistent groups for those specific instances. This configuration ensures that instance data survives scaling events and can be restored if needed.

Q: How do I restore a protected instance disk from a snapshot? A: Instance disks can be restored by leveraging the automatic snapshot policies and snapshot-consistent groups configured for the protected instances. This setup ensures that instance data survives scaling events and remains available for recovery when needed.
