The Edinburgh Multi-Access System (EMAS) has been described (Whitfield and Wight, 1973). The service now (March 1974) supports up to 55 simultaneous users from an accredited population of 500. File storage is provided on a 700M byte disc-file. Magnetic tape is used to provide backup and archive facilities for the file system. These facilities have been improved as use of the system expanded. Details of the use of tape as another level in the storage hierarchy are given and also included are outline plans to cope with two linked systems each with 700M bytes of disc-file and an ICL 4-75 processor.
