8.1.2 Remote Replication

NAS to NAS and Rsync

The NAS data can be backed up to a remote NAS or Rsync server by Rsync remote

replication. If the backup destination is a NAS, go to "Main Menu" > "Backup Station" >

"Rsync Server" and enable the remote NAS as an Rsync backup server.

1. To create a replication job, click "Create a Replication Job".

2. Specify the server type, NAS or Rsync server, of the remote server. Enter a job

name. Click "Next".

3. Enter the IP address, port number, username and password to login the remote

server. The default port number is 873. Note that the login username must have

read/write access to the remote server and sufficient quota limit on the server.

Click "Test" to verify the connection. Then click "Apply".

4. Specify the local folder by clicking the Source folder box. After expanding and

locating the folder, double click the folder to set it as the directory where the data

will be replicated from.

5. Specify the destination folder Destination folder box. Locate the folder in the folder

tree and double click the folder to set it as the directory where the data will be

replicated to. And, click "Add" to add this pair of replication folders.

6. Click "Backup frequency" to configure the backup frequency. Select to replicate the

data immediately or specify the backup schedule.

7. Specify other options as follows for the remote replication job by clicking the

"Options" button and click "Apply".

Enable encryption: Select this option to execute encrypted remote replication.

Note that you must turn on "Allow SSH connection" in "Network Services >

"Telnet/SSH" and specify the same port number for SSH and encrypted remote

replication.

Activate file compression: Turn on this option to allow file compression during the

data transfer process. This option is recommended for low bandwidth

environment or remote replication over WAN.

Perform incremental replication: When this option is turned on, after the first-

time replication, the NAS will only back up the files that have been changed

since the last backup. The files of the same name, size, and modified time will

not be copied again. You are recommended to turn on this option for the

replication job which will be executed for more than once in order to shorten the

backup time.
