Cluster protection
Your cluster protection will depend on the type of cluster configuration you are using.
● Standard cluster configuration—If you are using a standard cluster, where a
single copy of data resides on a SCSIdisk that is shared between cluster nodes,
you will be using the Double-Take Source Connection cluster resource to protect
your cluster.
● GeoCluster configuration—If you are using a GeoCluster configuration, where
data is stored on volumes local to each node and replicated to each node in the
cluster, you will be using the GeoCluster Replicated Disk cluster resource to
protect your cluster.
Protecting a standard cluster
Use the following steps to protect a standard cluster, where a single copy of data resides
on a SCSIdisk that is shared between cluster nodes. You will be using the Double-Take
Source Connection cluster resource to protect your standard cluster.
1. If your source is a cluster, create a virtual server (including resources for an IP
address, network name, and physical disk) on the source cluster. With this
configuration, users will access their data from the source cluster, regardless of
which node is currently in control. MSCS will handle failover between the nodes of
the cluster. Storage Mirroring Recover will handle failover between the source
cluster and the target (cluster or standalone). See your Microsoft documentation if
you need assistance creating a virtual server on the source cluster.
