Management class scenarios

Use management classes to determine how to manage your VM and vApp backups on the Tivoli® Storage Manager server.

The scenarios documented in this section are based on the correct use of the following Tivoli Storage Manager backup-archive client options: Therefore, before implementing a management class strategy based on these scenarios, make sure to review these options in Client options reference .

Management class scenarios in a vSphere environment

Use the vmmc option to store the VMware backups with a management class other than the default management class. The vmmc option is only valid when vmbackuptype=fullvm.

Task:
  • Run a backup of the virtual machine that is named myVirtualMachine.
  • Save the backup according to the management class myManagmentClass.
Command line:
dsmc backup vm "myVirtualMachine" -vmmc=myManagmentClass

By default, VMware control files are bound to the default management class. The vmmc option can be used to specify a different management class to which VMware data and VMware control files are bound. The vmctlmc option overrides the default management class and the vmmc option for VMware control files.

Under certain conditions, it might be desirable or necessary to bind VMware control files to a different management class than the VMware data files.

The vmctlmc option is required if VMware data files are backed up to tape. VMware control files must be backed up to a disk-based storage pool that does not migrate to tape. The storage pool can be composed of random access volumes and sequential file volumes; the storage pool can also be a deduplicated pool. Use the vmctlmc option to specify a management class that stores data in such a storage pool.

Restriction: The management class that is specified by the vmctlmc option determines only the destination storage pool for VMware control files. Retention of VMware control files is determined by the vmmc option, if specified, or by the default management class. The retention for the VMware control files always matches the retention of the VMware data files.
Options file:
vmctlmc diskonlymc
Command line:
Does not apply.

Management class scenarios in a vCloud environment

Use the vappmc option to store VMware vCloud vApp backups by using a management class other than the default management class. The default management class is defined on the server, for the domain that the node belongs to.

If you set this option in the options file for a data mover node, all vApp back ups that are performed by the data mover are stored as indicated by the specified management class.

mgmtclassname
Specifies a management class that applies to VMware vApp backups. If you do not set this option, the default management class of the node is used.
Tip: The management class that you specify on this option affects the storage of vApp data; the vmmc option does not apply to vApp data storage processing. However, the vmctlmc option does specify the management class that is used to store control files for both virtual machine backups and vApp backups.
Options file:
Specify a management class to use when the server stores all vApp backups:
vappmc MCPRODVAPPS
Command line:
dsmc backup vapp "org1,vdc1,vapp1" -vappmc=myManagmentClass
