Backup and Restore

Backup operations allow you to copy the data on your system to another storage medium, such as diskettes, tapes, and CDs, for archiving.

Restore operations allow you to recover information that may have been lost as a result of human or mechanical error. You must use the restore method that corresponds to the backup method used to create the archive volume to restore files, directories, filesystems, data partitions, disks, and partitioning information. There are several means of archiving and restoring data on your system.

  • Preparing emergency recovery media using the emergency_disk(ADM) and emergency_rec(ADM) commands is the first step in backing up your system. These commands create bootable media and tapes that archive the primary hard disk. These commands back up both user and system data and allow recovery from the unlikely occurrence that the system is not bootable and/or the hard disk is damaged. Typically, emergency recovery diskettes and tape(s) are created after all system and add-on software is installed. They only need to be recreated if you update your system software.

    These commands are described in ``Creating and using emergency recovery media''.

    Once emergency recovery media are created, additional data can be archived using any of the utilities described below.

  • The traditional SCO OpenServer utilities backup(ADM) and restore(ADM) are available for performing complete and incremental backups of user and application data.

  • cpio(C), tar(C), and volcopy(ADM) are basic system commands for archiving and copying files. cpio is especially suitable for transferring files between different types of UNIX systems.
