Changing basic settings

To change basic settings of a disk snapshot schedule:

Management console

CLI

Terraform

API

In the management console, select the folder where the schedule is located.
Select Compute Cloud.
In the left-hand panel, select Snapshots.
Go to the Snapshot schedules tab.
Next to the schedule you want to change, click and select Edit.
Edit disk snapshot schedule parameters:
- Name. The naming requirements are as follows:
  - The name must be from 3 to 63 characters long.
  - It may contain lowercase Latin letters, numbers, and hyphens.
  - The first character must be a letter and the last character cannot be a hyphen.
- Description.
- Under Create snapshots, specify disk snapshot frequency: By hour, By day, By week, or By cron expression. You must specify the disk snapshot time for the UTC±00:00 time zone.
- In the Starting on field, set the start date for your schedule.
- Select the disk snapshot retention policy:
  - Store all snapshots: Enables retaining all the snapshots created by this schedule.
  - Only the last: Specify the number of the most recent snapshots to retain or the number of days for which you want to retain the snapshots. Other snapshots created by this schedule will be deleted automatically.
  Note
  
  Quotas apply to the number and total amount of snapshots in the cloud.
Click Save.

If you do not have the Yandex Cloud command line interface yet, install and initialize it.

The folder specified in the CLI profile is used by default. You can specify a different folder using the --folder-name or --folder-id parameter.

View the description of the CLI commands for managing schedules:

yc compute snapshot-schedule --help
yc compute snapshot-schedule update --help

Get a list of schedules in the default folder:

yc compute snapshot-schedule list --format yaml

Result:

- id: fc852cvb1ipd5********
  folder_id: e1ea8s8l71li********
  created_at: "2022-09-28T13:25:02Z"
...
    expression: 10 19 ? * *
  snapshot_count: "7"
  snapshot_spec: {}

Update the parameters of the selected schedule:
```
yc compute snapshot-schedule update <schedule_name_or_ID> \
  --new-name <new_schedule_name> \
  --description <description> \
  --expression <cron_expression> \
  --retention-period <disk_snapshot_retention_period> \
  --snapshot-count <number_of_disk_snapshots> \
  --start-at <start_date_and_time> \
  --labels <labels>
```
Where:
- --new-name: New name for the schedule.
- --description: Description.
- --expression: Cron expression.
- --retention-period: Disk snapshot retention period in seconds (s), minutes (m), or hours (h).
- --snapshot-count: Number of stored disk snapshots. Use either --snapshot-count or --retention-period. See disk snapshot retention policies.
- --start-at: Start date and time. You can also specify a period related to the current time point. For example: "2022-12-31T16:39:00+05:00", "2h".
- --labels: List of labels in key=value format.
For more information about the yc compute snapshot-schedule create command, see the CLI reference.

Result:
```
done (3s)
id: fc8e52mvchb2********
folder_id: e1ea8s8l71li********
...
  expression: 36 14 */1 * *
snapshot_count: "3"
snapshot_spec: {}
```

If you don't have Terraform, install it and configure the Yandex Cloud provider.

Open the Terraform configuration file and edit the fragment with the schedule description:

Sample schedule description in the Terraform configuration

resource "yandex_compute_snapshot_schedule" "default" {
  name = "my-name"

  schedule_policy {
    expression = "0 0 * * *"
  }

  snapshot_count = 1

  snapshot_spec {
    description = "snapshot-description"
    labels = {
      snapshot-label = "my-snapshot-label-value"
    }
  }

  disk_ids = ["test_disk_id", "another_test_disk_id"]
}

Apply the changes:
1. In the terminal, change to the folder where you edited the configuration file.
2. Make sure the configuration file is correct using the command:
```
terraform validate
```
  If the configuration is correct, the following message is returned:
```
Success! The configuration is valid.
```
3. Run the command:
```
terraform plan
```
  The terminal will display a list of resources with parameters. No changes are made at this step. If the configuration contains errors, Terraform will point them out.
4. Apply the configuration changes:
```
terraform apply
```
5. Confirm the changes: type yes in the terminal and press Enter.

You can check the schedule update and its new configuration using the management console or this CLI command:

yc compute snapshot-schedule get <schedule_name>

Get the list of schedules using the list REST API method for the SnapshotSchedule resource or the SnapshotScheduleService/List gRPC API call.

You can create snapshots of network drives, such as HDDs, SSDs, and non-replicated SSDs, as well as ultra-high performance network storages with three replicas (SSD).

For non-replicated SSDs and ultra-high performance network storages with three replicas (SSD), the snapshot time is not determined.

To take snapshots of local disks residing on dedicated hosts, use Yandex Cloud Backup. This service supports Ubuntu, CentOS, CentOS Stream, and Windows Server.
Update a disk snapshot schedule using the update REST API method for the SnapshotSchedule resource or the SnapshotScheduleService/Update gRPC API call.

Changing a disk list

To edit a list of disks for which snapshots are scheduled:

Management console

CLI

API

In the management console, select the folder where the schedule is located.
Select Compute Cloud.
In the left-hand panel, select Snapshots.
On the Snapshot schedules tab, choose a schedule for which you want to change a disk list.
Change a disk list:
- To add a new disk, under Disks, click Add disk. In the window that opens, choose a disk to add to the schedule and click Save.
