Setting up a backup primary will not really help in a disaster recovery scenario. A backup primary is useful on a high availability setup, as described here: Understanding High Availability.
One thing you could do for DR is to have 2 instances of Tableau Server ready: one in production and one as backup. If at any point the production server goes down, you could redirect users to the backup server (this could be automated using a proxy/load-balancer, for example). For this to work, you'd need to keep the content synchronized in both environments as regularly as possible. Probably the easiest alternative is to use daily backup/restore operations as described here: Back Up Tableau Server Data.
I'd highly suggest contacting your Tableau representative for a more in-depth conversation and selecting the right strategy.
Hope this helps!
Hi Santiago Sanchez ,
As you suggested, now i am taking daily backup of active server and restoring it in standby server when active fails.
I have only 1 tableau server license which is used in active tableau server. on second machine i installed trial version.
Standby server will be up when primary or active fails.
when i stopping active server and restoring backup in standby server , license key is not updating in standby server. It still showing trail version will expire in N days.
I have a question here: Can I use same license key for standby server . If yes , how ?
Thanks in advance !!!!
Yes, You can use the same license . Tableau one license will work in one PROD & two non-prod environments. Your back up machine can be a non-prod environment and utilize this.
Let me know, if you have any questions.
Thanks & Regards
Madhu is on point! So long you only keep one server in production, you can use the same key. To activate your backup server you can follow the steps here: Upgrading from Trial to Licensed Version of Tableau Server | Tableau Software
