Options that are not specified will use their default values. | Options | Type | Required | Description | | --- | --- | --- | --- | | `--snapshotVolumeConfigDayOfWeekTypeCode` | String | Optional | Enables automatic snapshot creation and sets the schedule. - `-1` (daily) \| `0` (Sunday) \| `1` (Monday) \| `2` (Tuesday) \| `3` (Wednesday) \| `4` (Thursday) \| `5` (Friday) \| `6` (Saturday) - If the snapshot allocation ratio is `0`, this option is invalid. - Snapshots are automatically created on the specified days within the snapshot capacity limit. | ### Common options For information about the options common to all `vnas` subcommands, see [NAS (VPC) options](/docs/en/cli-vnas#%EC%98%B5%EC%85%98). ## Examples If the request to change the snapshot settings is successful, the configuration information for the NAS volume instance and the snapshot settings are returned. ### Command The command example is as follows: ``` ./ncloud vnas changeNasVolumeSnapshotConfiguration \ --nasVolumeInstanceNo 10234567 \ --snapshotVolumeConfigurationRatio 10 \ --snapshotVolumeConfigDayOfWeekTypeCode -1 \ --snapshotVolumeConfigTime 1 \ --regionCode KR \ --output json ``` ### Output The output example is as follows: ``` { "changeNasVolumeSnapshotConfigurationResponse": { "totalRows": 1, "nasVolumeInstanceList": [ { "nasVolumeInstanceNo": "10234567", "nasVolumeInstanceStatus": { "code": "CREAT", "codeName": "NAS creation status" }, "nasVolumeInstanceOperation": { "code": "NULL", "codeName": "NAS NULL OP" }, "nasVolumeInstanceStatusName": "created", "createDate": "2026-08-19T11:32:32+0900", "nasVolumeDescription": "Test NAS volume", "mountInformation": "192.0.2.10:/n123456_testnas01", "volumeAllotmentProtocolType": { "code": "NFS", "codeName": "NFS" }, "volumeName": "n123456_testnas01", "volumeTotalSize": 536870912000, "volumeSize": 483183820800, "snapshotVolumeConfigurationRatio": 10.0, "snapshotVolumeConfigPeriodType": { "code": "DAY", "codeName": "Daily" }, "snapshotVolumeConfigDayOfWeekType": { "code": "-1", "codeName": "Everyday" }, "snapshotVolumeConfigTime": 1, "snapshotVolumeSize": 53687091200, "isSnapshotConfiguration": true, "isEventConfiguration": false, "regionCode": "KR", "zoneCode": "KR-2", "nasVolumeServerInstanceNoList": [], "isEncryptedVolume": false, "nasVolumeInstanceCustomIpList": [], "isReturnProtection": false } ], "requestId": "", "returnCode": "0", "returnMessage": "success" } } ```
