-Agreement by both parties, assumes sufficient capacity in time of need (Big Assumption)
-Should only be considered if no other options, or perfect partner (i.e. subsidiary)
Term
Advantages of DPCP
Definition

-Most common of the implementations.
Term
Subscription Service Types
Definition
-Hot Site
-Warm Site
-Cold Site
Term
Hot Site
Definition
-Requires:
-Fully configured facility with electrical power, Heating Ventilation and Air Conditioning (HVAC)
*File and print servers and workstations
*Applications are installed on the servers
*Workstations are kept up to date
-Allows walk in with a data restoration and begin full operations in short time
-Remote journaling – mirroring transaction processing over high-speed connections may eliminate back up time.
Term
Advantages of Hot Site
Definition
-24/7 availability
-Exclusivity of use
-Immediately available
-Supports short and long term outage
Term
Disadvantages of a Hot site
Definition
-Most expensive
