PAK/UNPAK

The PAK utility compresses NonStop files. PAK compresses Guardian files into a single unstructured
archive file on any Expand-connected NonStop system. You can create a self-extracting archive
file or use UNPAK to decompress the archive file when needed.
PAK efficiently and compactly collects data, which is useful in situations such as transferring large
numbers of files to the Global Customer Support Center (GCSC) for analysis.
PAK and UNPAK work directly with BACKUP and RESTORE:
PAK uses BACKUP to read files so its syntax is identical to BACKUP syntax. For example, you
can use multiple file sets, wild cards, WHERE conditions and most BACKUP options.
UNPAK uses RESTORE to decompress files from the archive file.
PAK starts BACKUP, and UNPAK starts RESTORE.
To run PAK or UNPAK, the BACKUP and RESTORE programs must be available (that is, they
must exist and be secured so you can execute them).
Because PAK and UNPAK use BACKUP and RESTORE, you need to be familiar with these utilities.

RESTORE

The RESTORE utility copies files from a backup tape to disk, and displays tape file information.
This utility is essential for complete system management, especially after a disk failure or human
error causes disk data to be lost. The RESTORE utility has three modes of operation:
LISTONLY mode generates information about files on a backup tape without restoring the files
to disk.
File mode copies individual files to disk from a tape created by file-mode BACKUP.
Volume mode re-creates a whole disk volume from a tape that was created by volume-mode
BACKUP. Volume-mode RESTORE can be used only by the super ID (255,255), usually the
system manager or operator.
