● Volumes which are not already being replicated by another GeoCluster
Replicated Disk resource
● Volumes that are not physical disk resources
● Volumes that do not contain system files (The volume that you booted
Windows from will not be displayed.)
● Volumes that exist on all nodes of the cluster
● Network—Select the network that you want to use for Storage Mirroring
Recover mirroring and replication traffic. If you do not have multiple networks
established, you will only be able to select the one network that does exist. If
you do not select a network, Storage Mirroring Recover will use DNS to
determine a network route to use. Ideally, the networks used for various traffic
should be separated. This is dependent on the number of networks that you
established when you created the cluster and the priority assigned to each
network. For example, if you have two network routes, separate Storage
Mirroring Recover and your public traffic. If you have three routes, separate
the public traffic and then separate Storage Mirroring Recover from the
cluster heartbeat.
● Orphan files—An orphan is a file that exists in the target location but is not in
the source location. You can enable the resource to remove or delete
orphans during a mirror. If you choose to move orphan files, specify the
location where you want to move them. You should not select the system
volume for the orphan files because it could impact the stability of the cluster
service.

Depending on the compression algorithms available for your operating system,
you may see a slider bar indicating different compression levels. Set the level from
minimum to maximum compression to suit your needs.

● Full Mirror—All files in the replication set will be sent from the source to the
target.
● File differences—Only those files that are different based size or date and
time will be sent from the source to the target.
● Send data only if Source is newer than Target—Only those files that
are newer on the source are sent to the target.
Note:
If you are using a database application, do not use the newer option
unless you know for certain you need it. With database applications, it is
