Backup Central

I want to be able to use a different disklist for different runs. Other than use shell scripting to mv disklista to disklist is there a way to tell amanda what disklist to use during a run.

What needs to remain the same ? Similar tape pool ?
Soft link files between different amanda run and use
cron to choose which to run ?

What are you trying to achieve though ? What is the goal you
are shooting for ? You have proposed a solution but I don't know
what the problem statement was.

man amanda.conf:
diskfile string
Default: disklist. The file name for the disklist file
holding client hosts, disks and other client dumping
information.

You can use: amdump -odiskfile=disklista

Why do you want to do use different disklist file? You could have one
disklist and specify the DLE on the command line.

Thanks for the information about the -o option in amdump this is exactly
what I needed.

Several people have asked why I wanted to do this.

I have a perl script that runs ever day that produces a .sh script that does
the backup. There is a lot of pre and post processing around the amdump. The
perl script determines if it is the first Saturday of the month and will
create an archive .sh rather than a daily .sh.

In the .sh script I run another script that searches my users home directory
and builds a list of include files based on the first letter of each users
so that file users-a will have all the users that start with a and users-b
will have all the users that start with b and so on. This is run before each
amanda backup so that it will catch any new users that have been added.

Now my disk list file look like the following

zorn /export/users-a /export/fssnap/users {
users-tar
include list "/local/Amanda/UsersList/users-a"
}
:
:
zorn /export/users-z /export/fssnap/users {
users-tar
include list "/local/Amanda/UsersList/users-z"
}

I use the same DLE for both daily and archive backup and my DLEs are static.

The problem is that my user disk space has grown and it is taken a lot of
time to do an archive so I want to create two DLEs, disklist-a-m and
disklist-n-z, and do an archive on the first Saturday with a-m and on the
third Saturday with n-z. On the Archive days I will run amdump
-o-disklist=disklist-x-y base on what Saturday it is.

Sure -- supply the path to the disklist as a config overwrite:
amcheck -o disklist=disklist.red-days MyConfig
amdump -o disklist=disklist.blue-days MyConfig

You can also get creative with dumptype inheritance and the "ignore"
option, if you're so inclined.
