+# huaweicloud_evs_volume_transfers
+
+Use this data source to get the list of EVS volume transfers within HuaweiCloud.
+
+## Example Usage
+
+```hcl
+data "huaweicloud_evs_volume_transfers" "test" {}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `region` - (Optional, String) Specifies the region in which to query the resource.
+  If omitted, the provider-level region will be used.
+
+## Attribute Reference
+
+In addition to all arguments above, the following attributes are exported:
+
+* `id` - The data source ID.
+
+* `transfers` - The list of volume transfers.
+
+  The [transfers](#transfers_struct) structure is documented below.
+
+<a name="transfers_struct"></a>
+The `transfers` block supports:
+
+* `id` - The volume transfer ID.
+
+* `name` - The volume transfer name.
+
+* `volume_id` - The volume ID.
