since this option is only available for Windows VSS (https://docs.aws.amazon.com/aws-backup/latest/devguide/API_AdvancedBackupSetting.html), I'd prefer a simple switch rather than an arbitrary data structure.

for example, if say var.windows_vss_backup is true, then we enable this block:

advanced_backup_setting {
  backup_options = {
    WindowsVSS = "enabled"
  }
  resource_type = "EC2"
}

so maybe something like this instead:

variable "windows_vss_backup" {
  type = bool
  default = false
}

dynamic "advanced_backup_setting" {
  for_each = var.windows_vss_backup ? [true] : []
  content {
    backup_options = {
      WindowsVSS = "enabled"
    }
    resource_type = "EC2"
  }
}

Closing this as this should be resolved by #63
