creation_schedule

Job schedule name

uuid

string

Job schedule UUID

snapmirror_policy_rule

SnapMirror policy rule for retention.

Name Type Description

count

integer

Number of Snapshot copies to be kept for retention. Maximum value will differ based on type of relationship and scaling factor.

creation_schedule

creation_schedule

Schedule used to create Snapshot copies on the destination for long term retention. Only cron schedules are supported for SnapMirror.

label

string

Snapshot copy label

period

string

Specifies the duration for which the Snapshot copies are locked. The retention period value represents a duration and must be in the ISO-8601 duration format. Years, months, days, hours, minutes, and seconds are represented as "PY","PM","PD","PTH","PTM" and "PTS". Value "infinite" is also a valid input for Flexvol volumes and FlexGroup volumes. A duration which combines different periods is not supported, for example "P1Y10M" is not supported. The range of supported retention period values is between 1 second to infinite.

prefix

string

Specifies the prefix for the Snapshot copy name to be created as per the schedule. If no value is specified, then the label is used as the prefix.

preserve

boolean

Specifies the behavior when the Snapshot copy retention count is reached on the SnapMirror destination for the rule. The default value is false, which means that the oldest Snapshot copy is deleted to make room for new ones but only if the number of Snapshot copies has exceeded the retention count specified in the 'count' property. When set to true and where the Snapshot copies have reached the retention count, an incremental SnapMirror transfer will fail or if the rule has a schedule, Snapshot copies will be no longer be created on the SnapMirror destination.

warn

integer

Specifies the warning threshold count for the rule. The default value is zero. When set to a value greater than zero, an event is generated after the number of Snapshot copies (for the particular rule) retained on a SnapMirror destination reaches the specified warning limit. The preserve property for the rule must be true in order to set the warn property to a value greater than zero.

svm

SVM, applies only to SVM-scoped objects.

Name Type Description

_links

_links

name

string

The name of the SVM. This field cannot be specified in a PATCH method.

uuid

snapmirror_policy

SnapMirror policy information. SnapMirror policy can either be of type "async", "sync" or "continuous". The policy type "async" can be associated with a SnapMirror relationship that has either a FlexVol volume, FlexGroup volume or SVM as the endpoint. The policy type "sync" along with "sync_type" as "sync" or "strict_sync" can be associated with a SnapMirror relationship that has a FlexVol volume as the endpoint. The policy type "sync" can have a "sync_type" of either "sync", "strict_sync", "automated_failover" or "automated_failover_duplex". If the "sync_type" is "sync", a write success is returned to the client after writing the data to the source endpoint and before writing the data to the destination endpoint. If the "sync_type" is "strict_sync", a write success is returned to the client after writing the data to both source and destination endpoints. If the "sync_type" is "automated_failover", the policy can be associated with a SnapMirror relationship that has a consistency group as the endpoint and provides asymmetric active active access to the two storage copies. If the "sync_type" is "automated_failover_duplex", the policy can be associated with a SnapMirror relationship that has a consistency group as the endpoint and provides symmetric active active access to the two storage copies. Use the "sync" policy with "sync_type" as "automated_failover" or "automated_failover_duplex" to establish SnapMirror relationships for business continuity use cases. SnapMirror relationships with policy types as "sync" and "sync_type" as "automated_failover" or "automated_failover_duplex" can be monitored by the Mediator, if configured. If the source Consistency Group endpoint is not reachable, the Mediator might trigger a failover to the destination consistency group endpoint. A policy type of "continuous" can be associated with SnapMirror relationships that have either ONTAP S3 buckets or non-ONTAP object stores as endpoints. This type of policy is used for FabricLink owned targets.

Name Type Description

_links

_links

comment

string

Comment associated with the policy.

copy_all_source_snapshots

boolean

Specifies that all the source Snapshot copies (including the one created by SnapMirror before the transfer begins) should be copied to the destination on a transfer. "Retention" properties cannot be specified along with this property. This is applicable only to async policies. Property can only be set to 'true'.

copy_latest_source_snapshot

boolean

Specifies that the latest source Snapshot copy (created by SnapMirror before the transfer begins) should be copied to the destination on a transfer. "Retention" properties cannot be specified along with this property. This is applicable only to async policies. Property can only be set to 'true'.

create_snapshot_on_source

boolean

Specifies whether a new Snapshot copy should be created on the source at the beginning of an update or resync operation. This is applicable only to async policies. Property can only be set to 'false'.

identity_preservation

string

Specifies which configuration of the source SVM is replicated to the destination SVM. This property is applicable only for SVM data protection with "async" policy type.

name

string

Name of the policy.

network_compression_enabled

boolean

Specifies whether network compression is enabled for transfers. This is applicable only to the policies of type "async".

retention

array[snapmirror_policy_rule]

Rules for Snapshot copy retention.

rpo

integer

Specifies the duration of time for which a change to be propagated to a mirror should be delayed, in seconds. This is an intentional propagation delay between mirrors and is configurable down to zero, which means an immediate propagation. This is supported for policies of type 'continuous'.

scope

string

Set to "svm" for policies owned by an SVM, otherwise set to "cluster".

svm
