alibabacloud-oss-deletion-recovery-diagnosis

Read-only OSS diagnosis of accidental-deletion recovery and deletion residue: uses versioning to decide if a deleted object is recoverable, explains delete markers, leftover fragments, and why capacity/cost does not drop. States honestly when data is unrecoverable by official policy (versioning never enabled, lifecycle noncurrent version expiration, overdue-payment release). Triggers: "accidentally deleted how to recover", "delete marker", "BucketNotEmpty", "failed to delete bucket", "capacity not reduced after deletion", "file/object suddenly disappeared or returns 404, can it be recovered", "restore the deleted object to its previous version". Not for bill line-items (alibabacloud-oss-billing-diagnosis), the fragment cleanup procedure (alibabacloud-oss-multipart-upload-diagnosis), transfer or endpoint/region issues, lifecycle rule design, or restore/delete writes. Invoke immediately; missing bucket/region/object details are handled internally, never ask for supplements before invoking.
