If I understood the contant of the IDR, to protect my exchange 2010 server in the case of an Disater I need these:
1. an .dr file, this file will be created when I run a full backup of our exchange server.
2. Run a full backup of the exchange 2010 server.(C, D, E drive VSS volume shdow, system state)
3. Run the IDR wizard to create a bootable media for the exchange server.
I was looking at the default the location that the *.dr file should be created there on the media server and there I can see alrady an 2 .dr files and one is for the exchange 2010 server. so my question is when I run a full backup of the exchange server would this exsiting .dr file get updated or a new one would be created?
