8.1 Maintenance of Database

AdvancedCopy Manager holds various repositories of management information on the usage of its functions. They are named generically and are referred to as a database in this chapter.

The databases are important information and it is recommended that they be backed up periodically. Note that the databases referred to here differ from databases used for transactions, such as ORACLE databases.

The following table lists instances when backup of the database is needed.

Table 8.1 Databases on a Storage Server
Type	When a backup should be created	Backup method (references)	Size
Registry	A Storage Server has been added or Storage Management Server information (server name, IP address, or port number) has changed.	8.1.1.5.1 Backing up a registry or 8.1.2 Making a package backup of databases	Refer to 8.1.1.5.1 Backing up a registry.
Backup management list	A backup transaction has been completed.	8.1.1.1.1 Backing up a backup management list or 8.1.2 Making a package backup of databases	Refer to 8.1.1.1.1 Backing up a backup management list.
Volume configuration information (Backup management)	When the configuration of the volume group has changed	8.1.1.1.3 Preserving the volume configuration information	Refer to 8.1.1.1.3 Preserving the volume configuration information
Pre-processing and post-processing scripts for backup management	A pre-processing or post-processing script has changed.	Saving a database by using the copy command or 8.1.2 Making a package backup of databases	Check the size of the pre-processing and post-processing script files for backup management.
Pre-processing and post-processing scripts for tape-copy	A pre-processing or post-processing script has changed.	Saving a database by using the copy command or 8.1.2 Making a package backup of databases	Check the size of the pre-processing and post-processing script files for tape-copy.
Replication management list	A replication transaction has been completed.	8.1.1.2.1 Backing up a replication management list or 8.1.2 Making a package backup of databases	Refer to 8.1.1.2.1 Backing up a replication management list.
Volume configuration information (Replication management)	When the configuration of the volume group is changed	8.1.1.2.3 Preserving the volume configuration information	Refer to 8.1.1.2.3 Preserving the volume configuration information
Pre-processing and post-processing scripts for replication management	A pre-processing or post-processing script has changed.	Saving a database by using the copy command or 8.1.2 Making a package backup of databases	Check the size of the pre-processing and post-processing script file for replication management.
Policy file for management information package backup	The policy file has changed.	Saving a database by using the copy command or 8.1.2 Making a package backup of databases	Check the size of the policy file for management information package backup.

Point

You can create backups of databases either individually or as a whole.
If a Storage Server also operates as a Storage Management Server, the Storage Server contains a database for the Storage Management Server as well as for the Storage Server.
