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
To be able to replicate storage to another QNAP, you have to create a iSCSI target on second QNAP.
iSCSI target cannot include data!
In the first step go to QNAP's web panel and run the Control Panel.
In the next step, go to the storage and snapshot manager window.
Then select the iSCSI and Fiber Channel tab.
Select Create. A wizard window will be displayed, in which must define the parameters of the iSCSI storage being created. Remember to create iSCSI Target with a mapped LUN.
After the new storage is created, it will be displayed in the iSCSI target list.
After completing these steps, go to the QNAP web panel which running the Xopero server module and map the newly created iSCSI storage. To do this, go to the iSCSI and Fiber Channel window (Control Panel -> Storage & Snapshots -> iSCSI and Fiber Channel) and select the Add Virtual Disk button in the Remote Disk tab.
The form for adding a new virtual disk will be displayed. After filling it, the iSCSI resource will be mapped.
Then, go to Management Center and run Storage Manager.
To add a path to replicate, you can edit an existing store or do it by creating a new one.
