Figure 39 System configuration (In a Business Copy cascade configuration, when the volume subject
to backup operates both as the primary volume and the secondary volume)
In a Business Copy cascade configuration, Application Agent only supports backup and restore
operations for the pair volumes of the primary volumes used in the database or the file system.
When using a Business Copy cascade configuration as shown in
Figure 39 and the volume subject
to backup serves both as the primary volume and secondary volume, set the paired volume status
on the secondary volume to
SMPL and SSUS . Similarly, for restoration, set the status to SMPL .
• For the consistency group definitions It is necessary to consider how Application Agent backup
and restore operations are performed when defining consistency groups. Perform a backup or
restore operation after defining consistency groups as described below:
• Define consistency groups while considering the operations for restoring the databases. Pay
extra attention to the definitions if partial restoration of databases backed up at the same time
will be performed.
• For SQL Server databases
If restoring individual databases separately:
Define one consistency group to one database to make each database in a separate consistency
group.
If restoring multiple databases together:
It is possible to define consistency groups to make databases that are always restored together
in a same consistency group.
• For Exchange databases
If restoring individual Information Stores separately:
Define consistency groups to make each Information Store of data files (
*.edb , *.stm ) in a
same consistency group. In addition, define consistency groups to make the transaction log
files and checkpoint files (
*.log
,
*.chk
) of each storage group in a same consistency group.
If restoring multiple Information Stores together:
It is possible to define consistency groups so that the data files (
*.edb , *.stm ) of Information
Stores that are always restored together are in one consistency group. In addition, define
consistency groups to make the transaction log files and checkpoint files (
*.log , *.chk ) of
each storage group in a same consistency group.
If restoring individual storage groups separately:
Define consistency groups to make each file type of each storage group in a separate consist-
ency group. However, if rolling forward is not performed when restore and recovery operations
are performed, it is possible to define consistency groups to make all files of each storage
group are in a same consistency group.
If restoring multiple storage groups together:
