This section describes the function of making a backup of management information (e.g., databases) from just one Managed Server or Management Server.
With a package backup of management information, you can make a backup of management information for all Managed Servers and Management Server from just one Managed Server or Management Server. Executing a package backup of management information runs backup commands (making backups of backup management resources and databases) for the databases of other Managed Servers and Management Server, and collects the backup data and management information created by these backup commands.
The server on which you can execute a package backup of management information is called the "package-backup-of-the-management-information execution server". The servers whose data is to be backed up are called the "package-backup-of-the-management-information target servers".
Figure 11.1 Management Server and Managed Server
Assume that the package backup of management information function has been used to back up the management information on a Management Server, Managed Server A, and Managed Server B onto Managed Server B in the diagram above. In this case, Managed Server B is the backup execution server. The Management Server, Managed Server A, and Managed Server B are the backup target servers. That is, Managed Server B operates as both the backup execution server and backup target server.
The following table shows the types of management information that is handled in a package backup of management information.
Function | Type of data |
|---|---|
Database |
|
Registry |
|
Backup management |
|
Replication management |
|
Package backup of management information |
|
Note
Managed Server management information created by Softek AdvancedCopy Manager Version 10.3 (V10.0L40) or earlier cannot be handled by the package backup of management information function. To create a backup, back up each management information component individually as described in "Maintaining a database" in the ETERNUS SF AdvancedCopy Manager Operation Guide applicable to the Managed Server.
In an environment where the Managed Server with IPv4 address and the Managed Server with IPv6 address coexist, register the Management Server as a "package-backup-of-the-management-information execution server".
Before creating a package backup of management information, you must perform the following:
Determine the management information package backup target servers and the types of management information to be backed up.
Determine the management information package backup execution server.
Create a directory where the management information package backup execution server will store the backup data. The size of the directory must not be less than the total of the following sizes:
The required size for a database is the size of the database backup data multiplied by 1.2.
For the backup data size, refer to "Maintaining a database" in the ETERNUS SF AdvancedCopy Manager Operation Guide for the operating system running on the Management Server.
The required size for the registries is the total of the data sizes of the registry backup data on the management information package backup target servers.
For the backup data size, refer to "Maintaining a database" in the ETERNUS SF AdvancedCopy Manager Operation Guide for the operating system running on the management information package backup target server.
The required size for backup management is the total of the sizes below for each management information package backup target server:
For the size of each component of backup data, refer to "Maintaining a database" in the ETERNUS SF AdvancedCopy Manager Operation Guide for the operating system running on the management information package backup target server.
Size of the backup data for the backup management lists (size of the backup data for the backup management lists plus the size of the backup data for the recovery control files) multiplied by 1.2
Size of the pre-processing and post-processing scripts for backup management
Size of the transaction volume locking specification file for backups for backup management
Size of the backup volume locking specification file for backups for backup management
Size of the backup-restored volume locking specification file for backup management
The required size for replication management is the total of the following sizes for each management information package backup target server:
Size of the pre-processing and post-processing scripts for replication management
Size of the copy-source volume locking specification file for replication management
Size of the copy-destination volume locking specification file for replication management
Check the size of the working directory for the management information package backup target servers (or the shared disk for shared data for AdvancedCopy Manager in a clustered system). The sizes described below are needed only when a package backup of management information is being created. Use the largest value of the sizes of the databases to be backed up from the management information package backup target servers. The required sizes are as follows:
The required size for the databases is the size of the database backup data multiplied by 2.2.
For the backup data size, refer to "Maintaining a database" in the ETERNUS SF AdvancedCopy Manager Operation Guide for the operating system running on the Management Server.
The required size for backup management is the size of the backup data for the backup management lists (size of the backup data for the backup management lists plus the size of the backup data for the recovery control files) multiplied by 2.2.
For the backup data size, refer to "Maintaining a database" in the ETERNUS SF AdvancedCopy Manager Operation Guide for the operating system running on the management information package backup target server.
The working directory does not require any space for registry, replication management, and policy file backups.
Execute the stgmgrinfoset command as described in stgmgrinfoset (Management information package backup server registration/deletion command), on the management information package backup execution server (determined in step 2).
Create a policy file on the management information package backup execution server.
Management information package backup execution server | Policy file path | |
|---|---|---|
OS | Operation type | |
Windows | Non-cluster | <Environment directory>\etc\stgmgrinfo_policy.ini |
Cluster | <AdvancedCopy-Manager-shared-data>:\etc\opt\swstorage\etc\stgmgrinfo_policy.ini | |
Solaris, | Non-cluster | /etc/opt/FJSVswstf/stgmgrinfo_policy.ini |
Cluster | /etc/opt/FJSVswstf/<logical-node-name>/stgmgrinfo_policy.ini | |
Note
Do not specify more than one Managed Server as a management information package backup execution server.
When this server is used for executing transactions on the Managed Server in a clustered system, create a directory for storing backup data on a shared disk.
For databases and backup management, backup commands are executed on the corresponding management information package backup target servers. In addition, for database backups and backup management (ie, backup management lists) backups, a temporary capacity that is approximately 2.2 times greater than the total size of the backups is required to save the backup data in an archive log file.

Example
Set up a policy file as follows:
The Management Server named ACMMGR creates backups for the database and backup management.
The Managed Server named ACMAGT1 creates backups for backup management.
The Managed Server named ACMAGT2 creates backups for replication management.
[ACMMGR] DBData=Yes BkupData=Yes [ACMAGT1] BkupData=Yes [ACMAGT2] ReplData=Yes
Note
Create a policy file only if it will be used.
The policy file cannot include any settings for backups of registries and of the policy file for management information package backup.
Executing stgmgrinfobkup (Management information package backup command) on the management information package backup execution server stores the backup data in the directory under the following structure:
Directory | Data type | |||
|---|---|---|---|---|
*1 | Server | DBData |
| |
RegiData |
| |||
BkupData | FJSVswsts |
| ||
Scripts |
| |||
data |
| |||
ReplData | Scripts |
| ||
data |
| |||
MgrInfoData |
| |||
*1 is the backup data storage directory specified by stgmgrinfoset (Management information package backup server registration/deletion command).
When *1 is D:\ACMBkupData and the server name is ACMAGT1, the pre-processing and post-processing scripts for backup management are located in the following directory:
D:\ACMBkupData\ACMAGT1\BkupData\Scripts |
