[Backup](/cpp/docs/reference/spanner/2.23.0/classgoogle_1_1cloud_1_1spanner_1_1Backup). \nA Cloud Spanner backup is identified by an [`Instance`](/cpp/docs/reference/spanner/2.23.0/classgoogle_1_1cloud_1_1spanner_1_1Instance) and a `backup_id`.\n| **Note:** This class makes no effort to validate the components of the backup name. It is the application's responsibility to provide valid project, instance, and backup ids. Passing invalid values will not be checked until the backup name is used in a RPC to spanner.\n\nConstructors\n------------\n\n### Backup(Backup const \\&)\n\nCopy and move\n\n### Backup(Backup \\&\\&)\n\nCopy and move\n\n### Backup(Instance, std::string)\n\nOperators\n---------\n\n### operator=(Backup const \\&)\n\nCopy and move\n\n### operator=(Backup \\&\\&)\n\nCopy and move\n\nFunctions\n---------\n\n### instance() const\n\nReturns the [`Instance`](/cpp/docs/reference/spanner/2.23.0/classgoogle_1_1cloud_1_1spanner_1_1Instance) containing this backup.\n\n### backup_id() const\n\nReturns the [Backup](/cpp/docs/reference/spanner/2.23.0/classgoogle_1_1cloud_1_1spanner_1_1Backup) ID.\n\n### FullName() const\n\nReturns the fully qualified backup name as a string of the form: \"projects/"]]
