CRA1/9 - Digital Back-up of Records and Catalogue Files

Digital Back-up is maintained on both a series of CDs and a Portable Hard Drive.
Procedures are to be developed to ensure that these items are compatible with current technology and update/replaced as required. The items are to be stored in different secure locations.
The CDs will be held only as backup copies for as long as they remain readable. At some future date they will be obsolete and will be disposed of.
