archiver.cmd 文件示例

本节提供了一些归档配置示例。

示例 10-1 简单 archiver.cmd 文件

以下示例显示了一个可修改的简单 archiver.cmd 文件。仅为容纳更多的归档集、副本和 VSN 使用来添加指令。

archiver.cmd# One file system = samfs1
archmax = sg 2G
examine = noscan
fs = samfs1
logfile = /var/opt/SUNWsamfs/log/samfs1.log
all_archset .

endvsns

示例 10-2 高级 archiver.cmd 文件

以下示例显示了一个复杂的 archiver.cmd 文件。注释指出了各种指令类型。

# Global directives

archmax = li 8G

scanlist_squash = on

# Limit the drives

drives = stk50 3

# File selection

fs = samfs1
logfile = /var/adm/samfs1.log

archive.2 li .*
endvsns

示例 10-3 无 archiver.cmd 文件

本示例介绍了在某个 SAM-QFS 环境中未使用 archiver.cmd 文件时，归档程序的操作。该环境包括一个文件系统、一个配有两个驱动器的光盘自动化库和六个卡盒。

以下 archiver -lv 输出表明归档程序所选的默认介质类型为 mo。只有 mo 介质可用。

# archiver -lv
Notify file: /etc/opt/SUNWsamfs/scripts/archiver.sh
Archive media:
media:lt archmax: 512.0M Volume overflow not selected
media:mo archmax: 4.8M Volume overflow not selected

以下 archiver -lv 输出表明归档程序使用了两个驱动器。它列出了 12 个卷、存储容量和具有可用空间的 VSN。

Archive libraries:
Device:hp30 drives_available:2 archive_drives:2
Catalog:

mo.optic22 capacity: 1.2G space: 244.9k -il-o-------
mo.optic23 capacity: 1.2G space: 1.1G -il-o-------

以下 archiver -lv 输出表明归档集 samfs 既包括元数据，也包括数据文件。当文件的归档时间达到默认的四分钟（240 秒）时，归档程序将开始创建文件的副本。

Archive file selections:
Filesystem samfs Logfile:
samfs Metadata
copy:1 arch_age:240
samfs1 path:.
copy:1 arch_age:240

以下 archiver -lv 输出表明归档集中的文件按指定的顺序归档至卷中。

Archive sets:

示例 10-4 数据文件和元数据分开归档

本示例说明如何将数据文件和元数据划分至两个不同的归档集。除了光盘自动化库之外，环境中还包括一个手动挂载的 DLT 磁带机。较大的文件归档至磁带，而较小的文件归档至光盘卡盒。

以下示例显示了 archiver.cmd 文件的内容。

# archiver -lv -c example2.cmd
Reading archiver command file "example2.cmd"
1: # Example 2 archiver command file
2: # Simple selections based on size

示例 10-5 将用户文件和数据文件归档至不同的介质

在本示例中，用户文件和项目数据文件归档至不同的介质。data 目录中的文件按大小分别存储至光盘介质和磁带介质。指定给组 ID pict 的文件将被指定给另一个卷组。归档程序不对目录 tmp 和 users/bob 中的文件进行归档。归档程序每隔 15 分钟进行一次归档，并且保存归档记录。

示例 10-6 将用户文件和数据文件归档至光盘介质

在本示例中，用户文件和项目数据文件归档至光盘介质。

定义了四个 VSN 池。其中三个池分别用于用户、数据和项目，另一个是临时池。当 proj_pool 中的介质用尽后，将使用 scratch_pool 来保留卷。本示例介绍如何依据归档集、属主和文件系统等各个组成部分，来为每一个归档集保留卷。归档程序每隔 10 分钟进行一次归档，并且保存归档日志。

以下示例显示了 archiver.cmd 文件和归档程序输出。
