2.9 Intel® Rapid Recover Technology
Intel® Rapid Recover Technology utilizes RAID 1 (mirroring) functionality to copy data
from a designated master drive to a designated recovery drive. The master drive data
can be copied to the recovery drive either continuously or on request.
When using the continuous update policy, changes made to the data on the master
drive while the system is not docked are automatically copied to the recovery drive
when the system is re-docked. When using the on request update policy, the master
drive data can be restored to a previous state by copying the data on the recovery
drive back to the master drive.
Table 5 provides an overview of the advantages, the disadvantages, and the typical
usage of Intel® Rapid Recover Technology.

Hard Drives
Required:
2
Advantage:
More control over how data is copied between master and recovery drives;
fast volume updates (only changes to the master drive since the last update
are copied to the recovery drive); member hard drive data can be viewed in
Microsoft Windows Explorer*.
Disadvantage:
No increase in volume capacity.
Application:
Critical data protection for mobile systems; fast restoration of the master
drive to a previous or default state.
