Snapshot Replica
The Snapshot Replica allows you to replicate the volume/LUNs between different remote servers using
snapshot technology, which provides a flexible and efficient backup service for IT professionals.
To use this function, please enable the SSH server ("Control Panel" > "Network Services" >
"Telnet/SSH") on the remote NAS first. Note that you may also access this function via Storage
Manager ("Storage Manager" > "Storage Space"> "Snapshot" > "Snapshot Replica" for volumes or
"Storage Manager" > "iSCSI Storage"> "Snapshot" > "Snapshot Replica" for LUNs.)
Note:
Snapshots and related features are currently only available for the following NAS
series: x51*, x53, x63, x70, x71, x79, x80.

* A minimum of 4 GB RAM is required to use snapshots.

* x51 series models only support up to 256 snapshots instead of 1024. The HS-251
does not support snapshots.
Creating Replication Jobs
Follow these steps to create a snapshot replication job.
1. Click "Create a Replication Job".
2. Enter a name for this job.
3. Click "Settings" to specify the settings for the remote server. Enter the IP address, username and
password for the remote server. Check "Local site" if the replication job is for your local NAS. Note
that the login account must have read/write access to the remote server and sufficient quota limit
on the server. Click "Test" to verify the connection. Then click "OK".
4. Select the local volume to take snapshot of by clicking the "Source Volume/LUN" drop-down list.
5. Select the destination pool to store the snapshots in the "Destination Pools" box.
6. Keep Snapshots: The maximum number is 1024. The system keeps this fixed number of versions
and automatically rotates stored versions.
7. Click "Backup frequency" to configure the backup frequency. Select to replicate the data
immediately or specify the backup schedule.
8. Specify other options as follows for the remote replication job by clicking the "Options" button and
click "OK" after setup.
o Enable encryption: Select this option to execute encrypted remote replication. Note that you
must enable "Allow SSH connection" in "Network Services > "Telnet/SSH" and specify the
same port number for SSH and encrypted remote replication.
o Enable maximum transfer rate: Enter the value to restrict maximum available bandwidth in
KB/s. If it is not specified, the bandwidth for this job is not limited.
