Configuring the Cloud Appliance for Replication
TheReplicationwizard provides guided assistance for configuring theQ-Cloud Protectappliance to receive replicated data from an on-site DXi appliance or OpenStorage (OST) server. You can also use this wizard to configure theQ-Cloud Protectappliance to replicate stored data back to a source DXi appliance for failback recovery scenarios.
Source and Target Systems
Sourcessendreplicated data, and targetsreceivereplicated data. TheQ-Cloud Protectappliance can receive data from 1 source, and replicate data back to a single target. Although the cloud appliance is mainly used as a target for replicated data, it can serve as a source in failback recovery scenarios.
Step 1: About
- From theConfiguration Wizardspage, clickReplicationto display the Replication Wizard'sAboutpage.
Figure 1:Replication Wizard – About Page
- Review the information about the wizard.
- ClickNextto display theSystempage.
Step 2: System

Figure 2:System Page
- Configure the cloud appliance to receive replicated data.
Complete theSource Systemarea of the page
- In theSource Hostnames or IP Addressesbox, enter the hostname or IP address of the system that will send the replicated data to the cloud appliance.
You can specify only 1 replication source.
In theMaximum Snapshots Per Share or Partitiondrop-down box, select the number of snapshots to retain for each replicated share or partition (up to 32).
During scheduled or manual data replication, the cloud appliance receives a snapshot from the source system. A snapshot contains all data necessary to fully recover or failback a source to the point in time when the snapshot was saved.
- In theSource Hostnames or IP Addressesbox, enter the hostname or IP address of the system that will send the replicated data to the cloud appliance.
- Configure the cloud appliance to send replicated data in a failback recovery scenario.Complete the Target System area of the page
In theTarget Hostname or IP Addressbox, enter the hostname or IP address of the system that will receive the failback data.
When entering IP addresses, never use an address that is in a reserved IP address range. To see a list of reserved IP address ranges, click the quick tip icon[?]located near theIP Addressfield.
(Optional) Select an encryption option:
Encryption Option
Description
NONE
Data is not encrypted when sending failback data to the target system.
AES 128-BIT
Data is encrypted using AES 128-bit encryption when sending failback data to the target system.
Caution:选择128位加密如果你发送数据to a DXi appliance running a system software version prior to 2.1.
AES 256 BIT
Data is encrypted using AES 256-bit encryption when sending failback data to the target system.
In theSource IP Addressfield, enter the IP address that is used to uniquely identify the cloud appliance to the target. This may be different than the actual network IP address of the cloud appliance.
Note:If the target system is at 2.1 Software or higher, this field is not required. If the target system is at 2.0.1.x Software or below, then you must enter the IP address by which the target system recognizes the source system. The default value is0.0.0.0.

Step 3: NAS Share
IMPORTANT
Q-Cloud Protectis designed to be used as a replication target for on-site DXi appliances, on-site DXi appliances using OpenStorage (OST) optimized duplication, or Veritas NetBackup or BackupExec OST servers with DXi Accent enabled.
Q-Cloud Protectdoes not support use-cases for directly accessing data stored in NAS shares or VTL partitions from the cloud appliance. To access data stored in a share or partition from the cloud appliance, you must failback and recover the data at the source.

Configure the share to replicate its data to another DXi system or OST server.
Enter the following information under Send
- Select theEnable replication for selected sharecheck box to enable replication for the share.
(Optional) Select theEnable Directory/File based replication to targetcheck box to enableDirectory/File Based ReplicationWith Directory/File Based Replication, a file is automatically replicated when it is closed or a period of time after it is modified. After replication, the replicated files are immediately available on the target system.for the share, and then enter async IDThe Sync ID is used to identify the target share that will receive replicated data from the source share. The Sync ID must be identical to the Sync ID of the target share on the target system.in theSync IDbox.
- Select the check box for each replication target to which you want to replicate the share. When the share is replicated, its data will be sent to all selected targets.
