Replicating to DR from PRD

andrewl657 over 8 years ago

We have a distributed environment set up for our Production instance. F5 load balanced to 2 web servers, 2 app servers (active-passive), & clustered db. Our DR, on the other hand, is F5 to 1 web server, 1 app server, & 1 db server. Looking through the documentation on backup/replication, it mentions that it is necessary to have the exact same setup/configurations between DR and PRD.

We are not able to do that because our domain name and url for the DR will be different so we are not able to replicate the whole <APPIAN_HOME> directory. We have all engines & app data on a SAN that we plan to backup and replicate to our DR including RDBMS. Does anyone see any problems with this since the application setup will be different? Also I will be running the checkpointing script before every backup. Should we only be replicating the top 2 highest kdb files over to DR along with all app data and RDBMS?

Hey Mike. Thanks. We will have the same number of engines on both. We will be replicating only backed up kdbs and this will be every 4 hours. We are trying to avoid more than 4 hours of data loss but I am concerned that this frequency could cause performance issues in the future if the kdbs grow in size. What are your thoughts?
