Intel Rapid Recover Technology
Intel Matrix Storage Manager supports the following IRRT features.
Mirror update policies
With IRRT, you can determine how often the mirror HDD is updated: continuously or on-request. When
using the continuous update policy, data on the primary drive is simultaneously copied to the mirror drive
as long as both drives are connected to the system. If you undock the computer while using the docking
station recovery drive, all new or revised data on the primary HDD is automatically copied to the recovery
HDD when the notebook is re-docked. This policy also allows for an unfinished mirroring operation to
be completed if it was interrupted when you undocked the notebook.
When using the update on request policy, data on the primary HDD is copied to the mirror HDD only
when you request it by selecting Update Recovery Volume in IRRT. After the request, only the new or
updated files on the primary drive are copied to the mirror HDD. Prior to updating the mirror HDD, the
on-request policy allows a file to be recovered if the corresponding file on the primary HDD is corrupted.
The on-request policy can also protect data on the mirror HDD if the primary HDD is attacked by a virus,
provided you do not update the mirror HDD after the virus attack.
NOTE: You can change the mirror update policy at any time by right-clicking Modify Volume Update
Policy.
Automatic HDD switching and rapid recovery
If the primary HDD fails, IRRT automatically switches to the mirrored drive without user intervention.
IRRT displays a message to notify you of the primary HDD failure. In the meantime, the computer can
boot from the mirrored HDD. When a new primary HDD is installed and the computer is booted, IRRT’s
rapid recovery feature copies all mirrored data to the primary HDD.
NOTE: If using the update on request policy and the primary HDD fails or a file on the primary HDD
becomes corrupted, all unmirrored data is lost.
Simplified migration from RAID to non-RAID
Users can migrate from a RAID 1 or IRRT volume to two non-RAID HDDs, called “breaking the array,”
by following the instructions in
Resetting RAID drives to non-RAID on page 27 .
Migration from RAID 1 to IRRT is also supported. However, migration from RAID 0 to RAID 1 or from
RAID 0 to a non-RAID primary HDD is not supported.
