Description

Ticket: https://jira.mongodb.org/browse/CLOUDP-220487

• I installed the provider version 1.14.0
• I used the following TF conf

resource "mongodbatlas_project" "atlas-project" {
  name   = "test-andrea"
  org_id = "XXXXXXXXXXX"
}

resource "mongodbatlas_backup_compliance_policy" "backup_policy" {
  project_id                 = mongodbatlas_project.atlas-project.id
  authorized_email           = "user@email.com"
  authorized_user_first_name = "ssss"
  authorized_user_last_name  = "sss"
  copy_protection_enabled    = false
  pit_enabled                = false
  encryption_at_rest_enabled = false

  restore_window_days = 7

  on_demand_policy_item {
    frequency_interval = 1
    retention_unit     = "days"
    retention_value    = 3
  }

  policy_item_hourly {
    frequency_interval = 1
    retention_unit     = "days"
    retention_value    = 7
  }

  policy_item_daily {
    frequency_interval = 1
    retention_unit     = "days"
    retention_value    = 7
  }

  policy_item_weekly {
    frequency_interval = 1
    retention_unit     = "weeks"
    retention_value    = 4
  }

  policy_item_monthly {
    frequency_interval = 1
    retention_unit     = "months"
    retention_value    = 12
  }
