Backing up file systems means copying file systems to removable media (such as tape) to safeguard against loss, damage, or corruption. Restoring file systems means copying reasonably current backup files from removable media to a working directory.
This chapter describes the commands for scheduled backup and restore operations (ufsdump and ufsrestore); however, other commands are available for copying files and file systems for sharing or transporting files. The table below provides pointers to all commands that copy individual files and/or file systems to media.
