Hi Folks,
I now have three working configs, meaning that my test configuration can backup
three clients. I still can't tell what is happening, but that is a topic for a
different thread. There is not much difference among the configs; in fact the
only difference is the src (contents of "disklist") and the dst ("tapedev").
So, I have three clients, but the way I have configured AMANDA, I am running
three copies of AMANDA, none of which knows what any other is doing. They will
quite probably schedule level 0 backups on the same run, meaning I lose the
smoothing benefit of the scheduler, which wants to try to make the nightly
backup task approximately equal in terms of storage and network bandwidth
consumption. However, I recognize that I'm asking a single copy of AMANDA to do
multiple backups each night, and this might not be something AMANDA was
designed to do. I don't know, being relatively inexperienced.
The config specifies the src and dst of the backup where src is a set of DLEs
and dst is single tapedev. I think I want a single config that recognizes
multiple (src to dst) mappings, and AMANDA can make backup level decisions
knowing the full scope of the problem for that cycle. Given that I have fewer
clients than backup-cycles, I can space my level 0 backups so that I never do
more than one on any given night. I can fear that AMANDA will schedule everyone
for level 0 and backups are still proceeding the next day! That would be
disruptive and embarrassing.
I think what I'm asking is if I can backup a set of DLEs to a single tapedev,
and have a single copy of AMANDA run multiple backups each night? I can't mix
clients on the backup media, since each has different security and custody
requirements, and I think I'd like AMANDA to be aware of the complete set of
tasks for any given night without coming into conflict with AMANDA
doppelgangers, unless I'm inventing problems that don't exist and there is no
problem running multiple copies of AMANDA.
I may be looking to solve a non-problem, meaning that running multiple copies
of AMANDA each night is not a problem and hearing, "That is not a problem."
from those who know would be comforting.
Thanks for the help,
