Backup of the old traceables is created in file .slurp/userdata/{datarepository}/{nodeid}/{uploads}/{username}/oldtraceables.N.xml when user transfers selected traceables. The backup is done in ten rolling files, where the oldest file is removed. To restore a backup you need only to rename respective backup file to .slurp/userdata/{datarepository}/{trdname}/{username}/traceables.xml.
