Not at all. On the contrary!
Create a config for your daily backups called e.g. "daily".
Just label your tapes e.g. "Daily001" up to "Daily020", I mean use
numbers, not "Monday" or "Week1" or anything that is bound to some
particular event. Then insert them as amanda asks them.
Amanda aks the oldest tape first.
Then create a different config for archive, e.g. "archive".
Label them "Archive001" etc. Run this config once a week (but never
at the same time than your daily config). Insert tapes as amanda asks
them.
You can share a lot of the daily config like dumptypes, tapetypes etc.
if you store those parts in separate files and include them (see
"includefile" directive in amanda.conf man page).
You should probably use some options like "dumpcycle 0", and "record no"
etc in your archive config only.
I do it like:
$ cat ~amanda/etc/common/dumptypes.conf
## global COMMENTED OUT -- define dumptype global in
## amanda.conf before including this file
# define dumptype global {
# comment "GLobal definitions
# }
define dumptype user {
global
priority high
}
...
$ cat ~amanda/etc/archive/amanda.conf
# archive configuration
....
define dumptype global {
comments "Only full backups for archiving"
program "GNUTAR"
index yes
record no
compress client fast
skip-incr yes
dumpcycle 0
}
includefile "/home/amanda/etc/common/dumptypes"
...
$ cat ~amanda/etc/daily/amanda.conf
...
define dumptype global {
program "GNUTAR"
index yes
record yes
compress client fast
}
includefile "/home/amanda/etc/common/dumptypes"
...
The trick to separate the general options into subfiles,
that can be included in the amanda.conf. In the amanda.conf for
each config, you just specify what is peculiar for this config only.
Then if you really really want to be sure that both configs dump
the same filesystem, you could hard link the disklist files from both
configs, or run a little script with cron that compares both lists and
warns you if it goes out of sync. (With a script you can allow for
certain differences (e.g. don't backup /scratch in the archive config).

Make different configs, but use common parts by "include"-ing them
in the amanda config file, and by sharing the disklist file.
