Data_Protector_program_data\Config\Server\dr\p1s
(Windows Server 2008),
Data_Protector_home\Config\Server\dr\p1s (other
Windows systems), or /etc/opt/omni/server/dr/p1s
(UNIX systems) with the filename recovery.p1s.
(MC/ServiceGuard and Veritas Cluster specific term) A collection
of resources (for example volume groups, application services,
IP names and addresses) that are needed to run a specific
cluster-aware application.
(HP StorageWorks Disk Array XP specific term) A mirrored pair
of disks can have various status values depending on the action
performed on it. The three most important status values are:
• COPY - The mirrored pair is currently re-synchronizing. Data
is transferred from one disk to the other. The disks do not
contain the same data.
• PAIR - The mirrored pair is completely synchronized and
both disks (the primary volume and the mirrored volume)
contain identical data.
• SUSPENDED - The link between the mirrored disks is
suspended. That means that both disks are accessed and
updated independently. However, the mirror relationship is
still maintained and the pair can be re-synchronized without
transferring the complete disk.
Restoring backed up data to multiple disks at the same time (that
is, in parallel) by running multiple Disk Agents, that receive data
from one Media Agent. For the parallel restore to work, select
data that is located on different disks or logical volumes and
during backup, the data from the different objects must have
been sent to the same device using a concurrency of 2 or more.
During a parallel restore, the data for multiple objects selected
for restore is read from media at the same time, thereby
improving performance.
The concept of reading multiple data streams from an online
database.
Preparation for disaster recovery - the prerequisite condition for
a successful disaster recovery.
