Create a SnapMirror policy

POST /snapmirror/policies

Creates a SnapMirror policy. The property "identity_preservation" is applicable to only SnapMirror relationships with SVM endpoints and it indicates which configuration of the source SVM is replicated to the destination SVM.

It takes the following values:

  • full - indicates that the source SVM configuration is replicated to the destination SVM endpoint.

  • exclude_network_config - indicates that the source SVM configuration other than network configuration is replicated to the destination SVM endpoint.

  • exclude_network_and_protocol_config - indicates that the source SVM configuration is not replicated to the destination SVM endpoint.

Important note

  • The property "identity_preservation" is applicable to only SnapMirror relationships with SVM endpoints and it indicates which configuration of the source SVM is replicated to the destination SVM.

  • The properties "identity_preservation", "retention" and "transfer_schedule" are not applicable for "sync" type policies.

  • The property "sync_common_snapshot_schedule" is not applicable for an "async" type policy.

  • The property "retention.count" specifies the maximum number of Snapshot copies that are retained on the SnapMirror destination volume.

  • When the property "retention.label" is specified, the Snapshot copies that have a SnapMirror label matching this property is transferred to the SnapMirror destination.

  • When the property "retention.creation_schedule" is specified, Snapshot copies are directly created on the SnapMirror destination. The Snapshot copies created have the same content as the latest Snapshot copy already present on the SnapMirror destination.

Required properties

  • name - Name of the new SnapMirror policy.

  • svm.name or svm.uuid - Name or UUID of the SVM that owns the SnapMirror policy.

Default property values

If not specified in POST, the following default property values are assigned:

  • type - async

  • sync_type - sync (when type is sync)

  • network_compression_enabled - false

  • throttle - 0

  • identity_preservation - exclude_network_and_protocol_config

  • snapmirror policy create

Examples

Creating a SnapMirror policy of type "sync"

 POST "/api/snapmirror/policies/" '{"name": "policy1", "svm.name": "VS0", "type": "sync", "sync_type": "sync"}'

Creating a SnapMirror policy of type "async" with retention values

 POST "/api/snapmirror/policies" '{"name": "policy_ret", "svm": {"name": "vs1"}, "retention": {"label": ["smcreate"], "count": ["2"], "creation_schedule": ["weekly"]}}'

Creating a SnapMirror policy of type "async"

 POST "/api/snapmirror/policies" '{"name": "newPolicy", "svm":{"name" : "vs1"}, "type": "async"}'

Parameters

Name Type In Required Description

return_records

boolean

query

False

The default is false. If set to true, the records are returned.

return_timeout

integer

query

False

The number of seconds to allow the call to execute before returning. When doing a POST, PATCH, or DELETE operation on a single record, the default is 0 seconds. This means that if an asynchronous operation is started, the server immediately returns HTTP code 202 (Accepted) along with a link to the job. If a non-zero value is specified for POST, PATCH, or DELETE operations, ONTAP waits that length of time to see if the job completes so it can return something other than 202.
