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
