Data storage and retrieval tools are an important factor for thereliability of a facility. For accelerator studies and in case of a failure,an efficient and fast access to logged machine data is necessary. Inthis presentation we describe the implementation at the PSI protonaccelerator facility of the data storage and retrieval system with theassociated tools.
