Additional steps for updating virtual machines in Hyper-V Replica environments
Beginning with IBM Spectrum® Protect Plus Version 10.1.5, you can protect virtual machines (VMs) that are enabled to use the Hyper-V Replica feature.
IBM Spectrum Protect
Plus processes the data on the source and
replicated instances of the VMs separately. For example, if a VM named VM1
is on
the Hyper-V host named Host1
and the VM is replicated to Host2
,
IBM Spectrum Protect
Plus assigns the IDs
VM1@Host1
and VM1@Host2
to the VMs. You can then select one or
both of the VMs for data protection.
Considerations for VMs that are defined in existing SLA policies
If you update IBM Spectrum Protect Plus, you might have to take additional steps to ensure that data protection continues for VMs that are currently included in your service level agreement (SLA) policies.
An SLA policy can implicitly or explicitly include a replicated VM. You might be required to update the SLA policy when you update to IBM Spectrum Protect Plus 10.1.5 or later.
An example of an SLA policy that implicitly includes a replicated VM is a scenario in which the
policy protects all VMs on Host1
, which contains the VM VM1
.
VM1
is replicated to Host2
. In this scenario, a change to the SLA
policy is not required after you update IBM Spectrum Protect
Plus. The SLA policy creates a full backup of the instance of VM1
on
Host2
and creates a new full backup of the instance of VM1
on
Host1
. Existing backups of VM1
on Host1
that were
created before the update will expire based on the SLA policy retention settings.
An example of an SLA policy that explicitly includes a replicated VM is a scenario in which the
policy protects VM1
on Host1
, and VM1
is
replicated to Host2
. In this scenario, you must re-add the instance of the VM on
each host to the SLA policy after you update IBM Spectrum Protect
Plus.
