ECS Snapshot Archival to OSS for DR

Scenario

Configure automatic snapshots and snapshot-consistent groups for ECS disks, then export snapshot-based custom images to OSS buckets for long-term archival, cross-region replication, and disaster recovery compliance — a data protection lifecycle distinct from the existing maintenance-script scenario.

Q: How do I export ECS snapshots to OSS for long-term archival and cross-region disaster recovery? A: You can accomplish this by configuring automatic snapshots and snapshot-consistent groups for ECS disks and exporting the resulting custom images to an OSS bucket. This workflow establishes a dedicated data protection lifecycle for long-term archival, cross-region replication, and disaster recovery compliance.
