This section describes the function of making a backup of management information (e.g., databases) from just one Storage Server, Storage Management Server, or tape server.
With a package backup of management information, you can make a backup of management information for all Storage Servers, Storage Management Servers, and tape servers from just one Storage Server, Storage Management Server, or tape server. Executing a package backup of management information runs backup commands (making backups of backup management resources and databases) for the databases of other Storage Servers, Storage Management Servers, and tape servers, 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 8.1 Storage Management Server and Storage Server
Assume that the package backup of management information function has been used to back up the management information on a Storage Management Server, Storage Server A, and Storage Server B onto Storage Server B in the diagram above. In this case, Storage Server B is the backup execution server. The Storage Management Server, Storage Server A, and Storage Server B are the backup target servers. That is, Storage 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 | Database |
Authentication feature | Authentication management list |
Registry | Registry |
Backup management | Backup management list, or backup management list and recovery control file |
Replication management | Pre-processing and post-processing scripts |
Package backup of | Policy file |
Tape backup | Tape management information |
Note
Storage Server management information created by Softek AdvancedCopy Manager 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 Operator's Guide applicable to the Storage 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 Operator's Guide" for the operating system running on the Storage Management Server.
The required size for an authentication management list is the size of the authentication management list backup data.
For the backup data size, refer to "Maintaining a database" in the "ETERNUS SF AdvancedCopy Manager Operator's Guide" for the operating system running on the Storage 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 Operator's 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 Operator's 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
Sizes of the pre-processing and post-processing scripts for tape-copy
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
Size of the backup volume locking specification file for backups for tape copy
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
The required size for the policy file for package backup of management information is the size of the policy file backup.
The size required for tape management information is 1.2 times the size of backup of the tape management information.
For details on the size of tape management information, refer to "Maintaining Databases" in the "ETERNUS SF AdvancedCopy Manager Operator's Guide for Tape Backup Option".
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 cluster 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 Operator's Guide for the operating system running on the Storage Management Server.
The required size for the authentication management list is the size of the authentication management list backup data.
For the backup data size, refer to "Maintaining a database" in the Operator's Guide for the operating system running on the Storage 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 Operator's 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.
The size required for tape management information is 2.2 times the size of the backup of tape management information.
For details on the size of tape management information, refer to the section titled "Maintaining Databases" in the ETERNUS SF AdvancedCopy Manager Operator's Guide for Tape Backup Option.
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-setting-directory\etc\stgmgrinfo_policy.ini |
Cluster | <AdvancedCopy-Manager-shared-data>:\etc\opt\swstorage\etc\stgmgrinfo_policy.ini | |
Solaris HP-UX Linux AIX | 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 Storage Server as a management information package backup execution server.
When this server is used for executing transactions on the Storage Server in a cluster system, create a directory for storing backup data on a shared disk.
For databases, backup management, authentication management lists, and tape backup management, backup commands are executed on the corresponding management information package backup target servers. In addition, for database backups, backup management (ie, backup management lists) backups, and tape backup management information 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 file.
