3DC Multi-target
configuration A configuration in which, in addition to the local site, a connection is established
between a nearby remote site and a distant remote site and Continuous Access
Synchronous and Continuous Access Journal are used to copy storage system
volumes among the three sites (called a
data center ). Such a configuration
provides support for disaster recovery through the use of data at the distant
remote site.
If the delta resync function is used between the nearby and distant remote sites,
journal-copying of only the minimum data required is performed following a
failure, which minimizes the recovery time.
backup (replica)
catalog The backup catalog stores the replica history and the information pertaining to
generational backups. When a backup is performed, a new record that contains
information about the backup is created in the backup catalog. When restoring
data from a backup, Replication Manager references the information in the
backup catalog. Information stored in the backup catalog includes the following:
Backup start date and time
Backup source information
Backup destination information
batch collection
command for Software that collects necessary information, such as log files and properties files
that are related to a problem that cannot be resolved at the user level, for
forwarding to customer support.

cascade structure A structure of consecutive copy pairs. In a cascade structure, the secondary
volume of one copy pair is the primary volume of another copy pair. This volume
is called a
secondary/primary volume ( SP-VOL ).

configuration refers to a configuration that consists of an executing node
and a standby node, each of which includes a duplicate management server.
cluster software Software installed on management server nodes to boost overall availability by
duplicating management servers as a cluster system. Available software depends
on the OS that runs on the management server.
