A method of storing data processed during the operation of a data processing system, stored in the form of files in main storage means of the system and backed up by copying it to auxiliary storage means, includes, at transfer initiation times periodically recurring with a long period, transferring files stored in the main storage means of the system when it is operating from the primary storage area in which they are initially stored in the main storage means to a secondary storage area of the main storage means if they were not created and/or modified during the immediately preceding long period. Thus files recently created or modified can be processed separately from other files, to enable differentiated back-ups. |
