We are planning to implement a disaster recovery solution for a client involving replication in SQL Server 2012 Standard Edition but I'm struggling to get specifics on the licensing involved. We are planning on using two virtual machines with an instance of MSSQL Server 2012 Standard installed on each, one serving as a primary and the other a standby secondary
It's my understanding that we can do this with a single license, granted the secondary is purely passive outside of the replication itself, with no querying, backups or activity of any kind except in the case of a failure on the primary, in which case the secondary would have to pick up the slack until we get the primary back online.
Can anyone clarify the scenario for me or direct me to somewhere that I can gather more info? I've tried to find official Microsoft information regarding this but information is few and far between and mostly quite general/vague.
Thanks in advance
