We have to setup an application server which is web-based (LAMP stack) for which we are planning to procure the server with 10TB disk and with vmware hypervisor , the application server will be running on VM, it is very much important for us to setup a disaster recovery and business continuity for example if server crashes or due to physical damage at head office (primary site) goes down then the server at recovery site to ensure business continuity.
we have 2 branch offices one connected with mpls vpn to the head office where this new server going to be setup and another office is having leased line connectivity. please suggest on the following and which is the best one recommended you can add other plans please
1. while purchasing the dell server is there software if purchased and as well procure same identical config one more server and host it in the branch office, hence 2 servers of identical configurations and the software will mirror the volume and data - if primary site goes down the recovery site comes to live for the business continuity
2. OR should we have to look for automatic vm backup with veeam and this can be configured replicate from the primary site to the recovery site
please suggest thanks in advance.
