Note – The -reserve parameter is intended to reserve a volume for exclusive use

by one archive set. Many directories with a few small files cause many small archive

files to be written to each reserved volume. These small discrete archive files, each

with its own tar(1) header, slow the performance of the system.

The format for the -reserve parameter is as follows:

The value of keyword depends on the form you are using, as follows:

■ Archive set form –AsTABLE 3-17 shows, the set keyword specifies the archive set

component in the reserved name.

For example, the archiver.cmd file fragment in

CODE EXAMPLE 3-26 shows that the

line that begins with the allsets archive set name reserves volumes by archive set

for all archive sets.

■ Owner form – The dir, user, and group keywords, which are mutually

exclusive, specify the owner component in the reserved name. The dir keyword

uses the directory path component immediately following the path specification

of the archive set definition.

TABLE 3-18 shows examples.
