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/2.17.0/classgoogle_1_1cloud_1_1spanner_1_1Instance) containing this backup.\n\n### backup_id() const\n\nReturns the [Backup](/cpp/docs/reference/spanner/2.17.0/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/"]]
