5 discussion?? all of my questions are sited in a
clear maner, just below  Paul's comments.

>"this" is very unspecific.

The inital request asking for "a better way of doing
this" is in reference to my reply to paul, which was
enclosed in the forwarded message.

>Please ask your actual question rather than expecting
us toread all 100 lines and intuit your question.

The information was given in as breif a maner as
possible. 



---------------------------------------------------
Thank you for your reply Paul. Listed below are the
pieces of information that was missing in my
AMANDA.conf file:
runspercycle 5 days

What I want to do is use one tape a week/dumpcycle.
Yet, If I were to
use one tape per dumpcycle would AMANDA overwrite the
tape from one
day to the next. (i.e., If  AMANDA backed up 3 servers
on Monday to one tape,
 would it rewind and overwrite that tape during
Tuesdays dump?)

What is the syntax used when adding maxdumps # to the
AMANDA.conf
file? Is there a specific location where this variable
is placed? Sorry, I am
familiar with spindles, could you explain please?

I have appended the disklist file which has been
modified revealing their
directory naming conventions and purpose. I would
appreciate it if you
suggest what levels you think would be best.

holdingdisk hd1 {
    comment "main holding disk"
    directory "/var/tmp"        
    use -117 Mb }
The /var/tmp directory is backed up by AMANDA as shown
below.
