This chapter describes the overview of AdvancedCopy Manager.
AdvancedCopy Manager is a product that realizes storage management in an open system and provides the following solutions.
A hardware function [Advanced Copy Function (OPC, EC)] of Fujitsu Storage Systems ETERNUS is used to back up data fast. The advanced copy function, being a fast data copy function independent of a data size, can always maintain fixed backup time even if the data to be backed up increases. Thus, the backup time does not increase even if the data amount increases.
This function can drastically reduce the time in which work must be stopped to perform backup.
In addition, since operations management is linked to the following DBMS, high-speed backup can be performed without interruption to daily work.
Oracle
If work uses a database other than Oracle or uses a general file system, the time that work is interrupted is still significantly reduced.
With the remote copy function in the ETERNUS storage system, backup operations to disk array devices at remote locations is also possible.
By using AdvancedCopy Manager, the Oracle database can be backed up without stopping the application. Please refer to an "Sample Shell script for Backup Operations" about the backup method for the Oracle database.
Also AdvancedCopy Manager can backup independently of PRIMECLUSTER GDS, including the mirror volume (SDX object) environment.
The hardware function (advanced copy function [OPC/EC]) of the Fujitsu Storage Systems ETERNUS enables data to be used for purposes other than the original purpose and replicated data (copy) to be collected as a protection against data corruption.
With the remote copy function in ETERNUS storage system, copying operations to disk array devices at remote locations is also possible.
When using a shell script for DBMS linkage as explained below, high-speed copying without stopping transactions is possible.
Oracle
As an example for copying Oracle databases, the script created for replication is shown in "Sample Shell Script for Backup Operations."
AdvancedCopy Manager consists of the following two functions:
|
Function name |
Description |
|---|---|
|
Manager of AdvancedCopy Manager |
Operates on the Storage management server, and two or more Storage servers are managed. Backup management and replication management are performed. |
|
Agent of AdvancedCopy Manager |
Operates on the Storage server with which the storage device is connected. Backup management and replication management are performed. This product (Agent) can be managed by a manager of AdvancedCopy Manager running on the Solaris, the Windows, or the Linux operating systems. |
The Manager product includes the Agent function.
The AdvancedCopy Manager server type depends on the operating environment.
Storage server
The Storage server is a server which executes the backup operation and the replication operation that AdvancedCopy Manager offers. The Agent of AdvancedCopy Manager is installed on the storage server. If a storage server is also to be used as the storage management server then the Manager, as well as the Agent, will need to be installed. The Agent installation is included as part of the Manager installation.
Storage management server
The Storage management server manages the Storage servers and only one Storage management server can be set in the system.
The Manager of AdvancedCopy Manager is installed on the Storage management server.
Three different operating environments for the AdvancedCopy Manager are shown below:
When only one Storage server is installed
In this operating environment, only the Manager of AdvancedCopy Manager needs to be installed (Manager of AdvancedCopy Manager includes the Agent functions of AdvancedCopy Manager).
When two or more Storage servers are installed
When two or more AdvancedCopy Manager servers are available, set only one of them up as the Storage management server or set up a new server with no disk drive connected as the Storage management server. Each operation environment is explained below.
When the Storage server is operated as a Storage management server
One of the servers functions as a Storage management server. The Storage management server has a repository where the information on operating and management of all Storage servers is stored.
When many Storage servers exist, all of them compete for accesses to the repository. This will affect other applications running on to the same server. Therefore, the Storage management server should be considered as a dedicated server.
When the Storage server is operated as Storage management server, it becomes a composition shown next.
Setting up the special Storage management server
This setup composes of two or more Storage servers with a dedicated Storage management server.
The system configuration of AdvancedCopy Manager is shown below.
The following combinations of product levels of the AdvancedCopy Manager agent and manager can be used on different platforms.

There is a difference in functions at some product levels. Installation of the manager and agent of the same level is recommended.
With different-level connections, such combinations operate with a low range of functionality.
10.x, 11.0, V10.0Lxx, V11.0L10 in "Table 1.2 Combinations of products" are the version of Softek AdvancedCopy Manager.
The backup function of AdvancedCopy Manager provides operation management for high-speed backup by using the OPC (One Point Copy), ROPC (Remote One Point Copy), EC (Equivalent Copy), and REC (Remote Equivalent) function of a Fujitsu Storage Systems ETERNUS.
The following sub-sections provide more information concerning the backup function.
The advanced copy function (OPC/EC function) of the disk array unit is used to perform high-speed backup between volumes regardless of volume capacities. This function greatly reduces the impact of a backup operation.
Faster backups can be made by performing update differential copies using the Advanced Copy function.
The following sample shell scripts provide AdvancedCopy Manager commands and Oracle operations combined together:
Acquisition of DBMS (Oracle) resource information
Synchronization with DBMS (Oracle) and volume duplication
Additionally, the following functions allow you to manage the backup operation.
The policy management function manages the number of preservation generations of backup and the number of interval days in which backup should be performed (displays the delay when displaying information) for a volume to be backed up.
The storage configuration management function manages the configurations of volumes to be backed up and volumes to which a backup should be saved.
On AdvancedCopy Manager, a volume to be backed up is called a transaction volume; a volume to which a backup should be saved is called a backup volume.
The backup and restore functions back up and restore a specified volume.
Backup using ROPC/REC is limited to disk array devices within the same Storage Server that support ROPC/REC.
The history information management function manages, out of the information that has been backed up in the past, the information in preservation generations as history.
The consistency recovery function resolves inconsistencies in the AdvancedCopy Manager backup management information caused by a system or other type of failure.
The replication function of AdvancedCopy Manager provides operation management of replications by using the OPC (One Point Copy), ROPC (Remote One Point Copy), EC (Equivalent Copy), and REC (Remote Equivalent) function of a Fujitsu Storage Systems ETERNUS.
As a result, the following replication operations become possible.
The advanced copy function (OPC/EC function) of the disk array unit is used to perform high-speed replication between volumes regardless of volume capacities. This function greatly reduces the impact of a replication operation.
Faster backups can be made by performing update differential copies using the Advanced Copy function.
The consistency recovery function resolves inconsistencies in the AdvancedCopy Manager replication management information caused by a system or other type of failure.
In backup function, policy management and history management are possible, but they are not possible in replication function.
In replication function, replication between two volumes is possible.
The Web-GUI provided by AdvancedCopy Manager can be used to manage the users who have access to the system. This allows you to set up secure operations that specify the functions each user can access. Refer to "Security Operation Using Authentication Feature" in this manual for more information.
With AdvancedCopy Manager there are environmental setup and employment functions it is possible to carry out on a Web client screen. The main functions are as follows.
Security management
Operation restrictions of the user of AdvancedCopy Manager can carry out by GUI operation.
Backup management
Employment (a definition of a server or a device, backup, restoration, etc. to employ) of backup management of AdvancedCopy Manager can carry out by GUI operation.
replication management
AdvancedCopy Manager replication management tasks (such as defining volumes and executing replications) can be performed using the GUI.
A client screen can be used for accessing a management server using a WEB browser. The system with WEB browser does not have to have AdvancedCopy Manager installed.
Backup management and replication management can be done by commands as well as through a Web client screen.
For more information, see " AdvancedCopy Manager Web Client" in "ETERNUS SF AdvancedCopy Manager User's Guide".
One of the following hardware devices is required to perform backup management or replication management. In addition, an advanced copy license and cache table size need to be set up. The offered advanced copy function is different in each hardware device and confirm it to a Fujitsu systems engineer (SE).

The following devices are supported in backup management and replication management.
sd driver resources
MPHD resources
MPLB resources
Moreover, the unit of management is a disk partition unit.
PRIMECLUSTER GDS (hereinafter referred to as GDS)/SynfinityDISK is software whose main function is mirroring disk units.
AdvancedCopy Manager can backup and replicate the SDX objects of GDS/SynfinityDISK.
SDX objects are virtual resources managed by GDS/SynfinityDISK, and they include classes, groups, disks, volumes, and slices.
AdvancedCopy Manager can backup and replicate SDX objects in units of logical volumes or slices.
The format used to specify a device name in AdvancedCopy Manager is different depending on whether units of logical volumes or units of slices are to be used. Specify a device name as follows:
For operation in units of logical volumes
/dev/sfdsk/(class-name)/dsk/(volume-name)
For operation in units of slices
/dev/sfdsk/(class-name)/dsk/(volume-name):(devnam-value-of-sdxinfo)
Example: The class name is class1, the volume name is volume1, and the DEVNAM value of sdxinfo is sda.
For operation in units of logical volumes:
/dev/sfdsk/class1/dsk/volume1
For operation in units of slices:
/dev/sfdsk/class1/dsk/volume1:sda
PRIMECLUSTER GDS 4.1A30 or later and PRIMECLUSTER GDS Snapshot 4.1A30 or later are required to perform separate operations for each logical volume.
Operation in units of logical volumes and operation in units of slices at the same time on a single Storage server is not possible.
For details on backup of SDX objects, refer to the appropriate section titled "SDX Object Operations." For details on replication of SDX objects, refer to the appropriate section titled "SDX Object Operations."
