Output only. Amount of bytes that will be downloaded if the backup is
restored. This may be different than storage bytes, since sequential
backups of the same disk will share storage.
The resource name of the source Filestore instance, in the format
projects/{project_number}/locations/{location_id}/instances/{instance_id},
used to create this backup.
Optional. Input only. Immutable. Tag key-value pairs bound to this
resource. Each key must be a namespaced name and each value a short name.
Example:
"123456789012/environment" : "production",
"123456789013/costCenter" : "marketing"
