Hi Folks,
I have four servers, henceforth AMANDA clients, that I need to backup and a lot
of NAS space available. I'd like to configure AMANDA to treat each of the four
AMANDA clients as if it were the only client, meaning each client should have
it's own configuration which includes location for backup storage. I have a 3
TB staging disk on the AMANDA server. I have reasons for the individual
treatment of clients that include off-site storage requirements and differing
data sensitivity, so the simple solution is to be able to configure AMANDA to
treat each client as a single case, so I can provide for proper security and
custody of the backups. Can this be done?
Please refer to the small table below. I have some basic questions, but the
volume of documentation is difficult to grasp all at once, so please forgive
what might seem like trivial questions; they are not yet trivial to me.
Using 10.1.1.10 from the table below as an example:
1. I think I define the length of my tapes to be the maximum for a given
client backup, which is the size of a level 0 dump, which is 135 GB for the
example of 10.1.1.10. Since I want to configure AMANDA to treat each client as
an individual and not part of a collection of backup tasks, I assume AMANDA
will use one vtape per client per night. Can this be done? How do I qualify
configuration settings per client?
2. I have planned for one level 0 and five level 1 backups per week. Do I
call this "a cycle"? I think I need 185 GB storage per "cycle" and this tells
me how many "cycles", in this case, weeks, I can store before I have to re-use
tapes. Does this mean I can plan on a 43 cycle (week) retention of my backups?
Will AMANDA append to tapes, meaning can I put a full week on one vtape?
3. AMANDA will give me at least one level 0 dump per week per client. I
think this means that my backup "cycle" is 7, but I'm not sure what this is
called of where I define it. This can be global, for now, but I may have
occasions where the "cycle" is different from 7. Also, there will be one night
a week, when AMANDA will not do a backup, because I will be doing a disk image
backup, so I need to know how to turn off, say, Saturdays. (If there is a way
to include a disk-image backup in AMANDA discipline, I would be very interested
to read about it.)
So, somewhere I have to tell AMANDA "135 GB". "7", "185 GB" and "43", and I
have to do something similar for each of my four clients. What are the names of
the configuration settings, which have the values "135 GB", "7", "185 GB" and
"43" , and where do I put them so that they are qualified per client?
10.1.1.10 10.1.1.11 10.1.1.12 10.1.1.13
Level 0 (GB) 135 135 40 40
Level 1 (GB) 10 10 5 5

Thanks for the help,
