Replication is a process of duplication information between different servers. This operation allows you to limit the amount of data lost during the failure and restore the system to work.
Creating a iSCSI resource

In the first step, log in to the selected server (it can be a domain controller to which other servers are connected) as Administrator, go to the Server Manager and choose the option related to adding roles.
In the Wizard that will be displayed, select the role File and Storage Services -> File and iSCSI Services
After going through all the wizard steps, open the installed role and then go to the iSCSI option.
In the next step go to Tasks -> New iSCSI Virtual Disk
In the first wizard window, select the server and disk or path where the resource should be created.
Next, enter the name, select the amount of memory to be allocated for the resource and select an existing target or create a new one.
In the case of creating a new target, wizard will carry out the user through the stages of creating the target.
First define its name, then select the computer that should have access to the resource. Please remember that this have to be the host on which the Xopero Backup&Restore application is installed.
