Thanks everyone for the input. I copied the directory to the backup server and
everything is working fine.
As for the possibility of corrupting the backup database that Oliver mentioned
I already have a user with read only privileges to use so no changes will be
made from that server.

I think I forgot one important information.
Racktable is just php code that fetch all its data from the database. You
could just copy the webapp from server1 to server2 and change the configuration
file to set the slave database as its database. *no need to run the install or
anything. Copy paste folder and update configuration file.
But by doing that, you are risking to have split brain issue... The
application racktable wasn't developed to work in that type of environment and
won't do any sanity check to prevent corruption. Racktable is not cluster
aware.
When you work in clustering at the infra level, it is important to have an
application that is aware of the cluster or do abstraction *like in
virtualization* to avoid corruption of data.

Subject: [racktables-users] Installing DR racktables server
I have setup mysql to replicate the racktables database to another server. I
am now trying to install racktables butI get to step 5 of 7 and the installer
says:
Your database is already holding 65 tables, so I will stop here and let you
check it yourself.
There is some important data there probably.
Is there a way around this? I suppose I could install to a new db and then
import all the tables but then I would need to set up the replication all over
again.
