74 Sun StorageTek SAM Archive Configuration and Administration Guide • Version 4, Update 6, 04/07

The pseudo archive set allsets provides a way to set default archive set directives

for all archive sets. All allsets directives must precede directives for actual archive

set copies. Parameters set for individual archive set copies override parameters set

by the allsets directive. For more information on the allsets archive set, see the

archiver.cmd(4) man page.

The following subsections describe all archive set processing parameters, with the

exception of disk archiving parameters. For information on disk archiving

parameters, see “About Disk Archiving” on page 91.

Controlling the Size of Archive Files: -archmax

The -archmax directive sets the maximum file size for an archive set. This directive

has the following format:

This directive is very similar to the archmax global directive. For information on

that directive, and the values to enter for target-size, see “The archmax Directive:

Controlling the Size of Archive Files” on page 53.

Setting the Archiver Buffer Size: -bufsize

By default, a file being archived is stored in memory in a buffer before being written

to archive media. You can use the -bufsize directive to specify a nondefault buffer

size. These actions can improve performance, and you can experiment with various

buffer-size values.

This parameter has the following format:

For buffer-size, specify a number from 2 through 32. The default is 4. This value is

multiplied by the dev_blksize value for the media type, and the resulting buffer

size is used. The dev_blksize value is specified in the defaults.conf file. For

more information on this file, see the defaults.conf(4) man page.

For example, this parameter can be specified in the archiver.cmd file in a line such

as the following:

myset.1 -bufsize=6

-archmax target-size

-bufsize=buffer-size

1 2 ... 93 94 95 96 97 98 99 100 101 102 103 ... 287 288
