HP-UX System Administrator's Guide: Overview

• vxdump
vxdump copies to magnetic tape all files in a VxFS file system that have been
changed after a certain date. See vxdump(1M).
• fbackup (recover data using frecover), an HP-UX specific backup utility for
backing data up to the previous media types.
• tar
tar (called the “tape archiver”) can write to disk archive files or optical media.
tar is compatible with many other operating systems, including other versions
of UNIX, Linux, and Microsoft Windows.
• cpio
The cpio command saves and restores archives of files on magnetic tape, other
devices, or a regular file, and copies files from one directory to another while
replicating the directory tree structure. When cpio completes processing the files,
it reports the number of blocks written.
In addition to backing up to removable media, you can copy important files to another
system using ftp, rcp, or (for secure copies) sftp.
How Storage is Addressed
The various components that comprise the HP-UX storage stack are addressed in
different ways:

How it is addressedStack Component
Once created, a file system is usually addressed by its mount point, the directory
in the HP-UX directory tree that represents the root of the files in that file system.
File System
Not all logical / physical volumes contain file systems. Other uses of these
volumes include:
• swap space
• dump space
• database managed space
Swap and dump space are managed by the kernel, and database managed
space is usually managed by the database application.
