The rapid transition from centralized data processing to company-wide distributed information technology has resulted in a substantial increase in the number of remote computers – in particular workstations and PCs – involved. These remote computers are now extremely powerful. Large volumes of data can be stored on their hard disks.
HSMS enables files from remote networked UNIX computers to be backed up, archived and, if necessary, restored without the need for a buffer in BS2000 Migration, import and export are not supported for remote computers.
A file system of a UNIX workstation or parts of it can be mounted in the BS2000-UFS (POSIX) using NFS if an NFS server is installed on the UNUX client and the corresponding directory is exported. In this way HSMS accesses the files of the remote UNIX system which are to be saved or restored. From the HSMS viewpoint the remote UNIX is a passive node, i.e. no separate backup software is required on UNIX to perform the backup.
