Iii. Configure backup Parameters

Use the amandabackup account to log on to the cp1 machine and create the Amanda configuration directory.

Root @ cp etc: # su-amandabackup

-Bash-3.00 $ mkdir/etc/amanda/FileBackup

Copy the/var/lib/amanda/example/amanda. conf file to the/etc/amanda/FileBackup/directory. This amanda. conf file is the most important configuration file of the Amanda service.

-Su-3.2 $ cp/var/lib/amanda/example/amanda. conf/etc/amanda/FileBackup/

The current configuration file contains more than 700 lines, but most of them are comments, which give a more detailed explanation of the configuration parameters for each line. Below I will list some configuration parameters that need to be modified, not mentioned, you don't need to worry about him.

Open the amanda. conf file and edit the following content:

Here we use a virtual tape. Next we need to define the size of the virtual tape, edit the file, and add the following lines:

Define tapetype HARDDISK {

Comment "hard disk as virtual tape"

Length 20480 mbytes

}

Next, we need to define the Authentication Mode and find the "define dumptype global" section. Before "}", add the auth "bsdtcp" line.

Switch to the root account to create a backup cache directory.

Root @ cp1 :~ # Mkdir-p/dumps/amanda

Root @ cp1 :~ # Chown amandabackup: disk/dumps/amanda

Root @ cp1 :~ # Chmod 750/dumps/amanda

Next, we need to create a virtual tape directory. In the amanda. conf file, the default number of disk slots is 25 by default.
