Name Type Description

_links

_links

archive_retrieval_priority

string

This is supported for transfer of restore relationship only. Priority level at which objects are restored from the archival storage. The value can be high, standard or low. The cloud provider's lowest priority will be used as the default. It is only supported for object store SnapMirror relationships. If the objects were not archived, the property will be ignored.

bytes_transferred

integer

Bytes transferred

checkpoint_size

integer

Amount of data transferred in bytes as recorded in the restart checkpoint.

end_time

string

End time of the transfer.

error_info

error_info

Error information for the transfer.

files

array[files]

This is supported for transfer of restore relationship only. This specifies the list of files or LUNs to be restored. Can contain up to eight files or LUNs.

last_updated_time

string

Last updated time of the bytes transferred in an active transfer.

network_compression_ratio

string

Specifies the compression ratio achieved for the data sent over the wire with network compression enabled. This property is only valid for active transfers.

on_demand_attrs

string

Specifies whether or not an on-demand restore is being carried out. This is only supported for the transfer of restore relationships for entire volumes from the object store. A value for read_write_with_user_data_pull should be provided to start an on-demand restore. A file restore from the object store does not support this option.

options

array[options]

Options for snapmirror transfer.

relationship

relationship

snapshot

string

Name of Snapshot copy being transferred.

snapshot_retention_period

string

Specifies the duration for which the Snapshot copy specified in the 'source_snapshot' property is locked in the object store. The retention period value represents a duration and must be specified in the ISO-8601 duration format. The retention period can be in years, months, or days. A period specified for years, months, or days is represented in the ISO-8601 format as "PY", "PM", or "PD" respectively. For example, "P10Y" represents a duration of 10 years. The period string must contain only a single time element, that is, either years, months, or days. A duration which combines different periods is not supported, for example "P1Y10M" is not supported. Years, if specified, must be less than or equal to 100. Months, if specified, must be less than or equal to 1200. Days, if specified, must be between and including 30 and 36500. This property is valid only if the 'source_snapshot' property is specified and when the property 'snapshot_lock_mode' in the policy associated with the SnapMirror relationship is set to enterprise or compliance. If this property is not specified and the source Snapshot copy being transferred does not match a policy rule, then a default retention period of "P30D" is set. This property is supported only for non-restore transfers and for object store SnapMirror relationships.

source_snapshot

string

Specifies the Snapshot copy on the source to be transferred to the destination.

source_snapshot_uuid

string

Specifies the Snapshot copy UUID on the object store source to be restored to the destination.

state

string

Status of the transfer. Set PATCH state to "aborted" to abort the transfer. Set PATCH state to "hard_aborted" to abort the transfer and discard the restart checkpoint. To find "queued" transfers refer to relationships GET API.

storage_efficiency_enabled

boolean

This is supported for transfer of restore relationship only. Set this property to "false" to turn off storage efficiency for data transferred over the wire and written to the destination.

throttle

integer

Throttle, in KBs per second. This "throttle" overrides the "throttle" set on the SnapMirror relationship or SnapMirror relationship's policy. If neither of these are set, defaults to 0, which is interpreted as unlimited.

total_duration

string

Elapsed transfer time.

uuid

string

Unique identifier of the SnapMirror transfer.
