Description

I want to create create disk snapshots of type ARCHIVE as a scheduled, recurring event.
As detailed here, https://cloud.google.com/compute/pricing-announce, the price difference between the STANDARD and ARCHIVE snapshot types are substantial (2-3x), and the 90 day retention period of the ARCHIVE type is typically of no issue since disk snapshots are generally used for backup purposes.

I fail to find the ARCHIVE snapshotType supported in the current Terraform Google provider.

The ARCHIVE snapshotType, a.k.a. "Persistent Disk Archive Snapshots" is mentioned in this Google blog post:
https://cloud.google.com/blog/products/compute/long-term-data-protection-persistent-disk-archive-snapshots

New or Affected Resource(s)

• google_compute_resource_policy

Add a snapshot_type to the snapshot_properties block. Where valid options are STANDARD(the default) and ARCHIVE.

Potential Terraform Configuration

resource "google_compute_resource_policy" "daily_snapshot_policy" {
  name   = "daily-snapshot-policy"
  snapshot_schedule_policy {
    schedule {
      daily_schedule {
        days_in_cycle = 1
        start_time    = "04:00"
      }
    }
    snapshot_properties {
      snapshot_type = "ARCHIVE"
    }
  }
}

will look into this

https://cloud.google.com/compute/docs/reference/rest/beta/resourcePolicies/insert does not seem to support it on the schedule resource (yet?)
