Disaster Recovery | 2 instances scenario
aprcatarinanovo
Member Posts: 2
Hello!
I have a Customer that wants to create a Disaster Recovery scenario for Dynamics NAV. They want to have 2 different NAV instances on different servers and if a server goes down for any reason, they'll have another instance to turn on and don't loose work and time.
The idea is if an instance goes down, they can turn on the another right away.
Is this possible? What are the requisites for that?
Thank you!

This is not a Disaster Recovery scenario, just a backup of the NST server. Such a setup will offer just a downtime protection, as it enables you to quickly switch on to the backup NST server, but nothing more that that.
What you really need is to protect the SQL Server, and the NAV database living on it. The Disaster Recovery usually means a cross-site instalation, and/or off-site held backups, so if a real disaster strikes (a flood, fire, an earthquake, a bomb/terrorist attack) your data is safe and accessible in some fairly remote site.
Data protection wise the transactions in progress will be lost in any case, regardless if you only duplicate tthe NST server, or if you build a £1M DR solution. The data needs to hit the SQL Server and get committed to be protected, one way or another.
The DR instalation subject is quite wide and deep topic, with many variables and many goals/targets to be set. That includes financial targes, how much data/time, ergo money, you can afford to loose and in result how much you can spend to protect both. There are tons of books on the subject, it is not really a matter of a simple question to be answered on a forumSlawek Guzek
