Kevin,

The only reason you might want to replicate the Maps (Disabled) folder on
the secondary InterMapper server would be if you needed to restore a
disabled map while awaiting the primary InterMapper server to come back
online. This is assuming that you are also backing up the primary server's
InterMapper Settings folder in the event of a complete failure of the
system, as I am sure you want to preserve all your chart data, web pages,
etc. that are not being copied over to the secondary server. The only
problem I can see with licensing is that you will want to be sure not to
copy the InterMapper License.txt file from the primary to the secondary
server, as that will overwrite the secondary server's license file.

You will want to backup your Preferences file to the secondary server, and
if you are using any custom probes, you will want to copy the Probes folder
over as well. If you are using any command-line probes that run an
application or script located in the Tools directory, you will need to copy
that folder over as well.

Subject: RE: [IM-Talk] Backing up Intermapper

Great thread and coincidental for we are looking at disaster recovery with a
second (and maybe third)
Intermapper server in different buildings.

There are over 4 gigs of stuff (old chart data and logs) but only around 15
megs in maps and maps (backups).
And another 10 megs in web pages, icons etc.  I have archived some data
already.

Our intent at the moment is to use FRS to replicate files to a second server
which Intermapper is installed with it's own licence but not running but
without chart/log data.  When the main IM dies, NOC pers would turn on the
secondary.

Whenever the main comes back up, we would abandon anything on the backup IM,
turn it off and bring the main back online.
We would suffer the loss of chart data/logs for the period of time the main
Intermapper is down.

Having said that, is there any particular reason to replicate the disabled
maps and backups?
Is there a problem having a second licensed server and not using the license
from the main server?

Can you see anything wrong with this idea?  Any improvements?
We will be implementing "something" shortly to test.

Kevin

The chart definitions are stored in the Map files. The actual chart history
(datapoints) is stored in the Chart Data
folder, but those files will be recreated anew if you don't back them up.
So, if you don't care about the chart history,
don't back up the Chart Data folder.

If you have a typical system (i.e. one without custom probes, custom icons,
or custom web pages) you should back up
these files and directories:

  InterMapper Settings/InterMapper License.txt
  InterMapper Settings/Preferences
  InterMapper Settings/Maps/
  InterMapper Settings/Maps (Disabled)/
  InterMapper Settings/Maps (Backups)/

If you care about log files, you should also back up:

  InterMapper Settings/InterMapper Logs/


All the other folders in the InterMapper Settings directory will be
re-created by InterMapper the next time it starts
up, if they don't exist, with their default contents.
