Defining consistency groups and P9000 RAID Manager
It is important to consider how backup and restore operations are performed when defining consistency
groups, especially if you plan on performing partial database restorations.
For SQL Server databases
When restoring individual databases:
Define one consistency group to one database so that each database is in a separate consistency
group.
When restoring multiple databases:
If you want databases to be restored together, place them in the same consistency group.
NOTE:
Define one consistency group as one group (dev_group) of P9000 RAID Manager configuration
definition files so that there are never too many or too few copy groups.
For Exchange databases
When restoring individual information stores:
Define consistency groups to make each information store of data files ( *.edb , *.stm ) in the same
consistency group. In addition, define consistency groups to make the transaction log files and
checkpoint files (
*.log , *.chk ) of each storage group in the same consistency group.
When restoring multiple information stores:
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 the
same consistency group.
When restoring storage groups (individual or multiple):
Define consistency groups to make files of each file type of each storage group in a separate
consistency group. However, if rolling forward is not performed when restore and recovery operations
are performed, it is possible to define consistency groups to ensure the files of each storage group
are in the same consistency group.
Replica data types and configuration requirements
This topic describes the types of data associated with replicas and specific configuration requirements
for Exchange and SQL Server databases to ensure the data is accessible.
