GException on failure.
Replaces the contents of file with contents of length bytes. If etag is specified (not NULL), any existing file must have that etag, or the error G_IO_ERROR_WRONG_ETAG will be returned. If make_backup is TRUE, this function will attempt to make a backup of file. If cancellable is not NULL, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error G_IO_ERROR_CANCELLED will be returned. The returned new_etag can be used to verify that the file hasn't changed the next time it is saved over.
