Remote Replication
This chapter covers the following topics:
 NAS to NAS and Rsync
 RTRR
 Downloading Replication Job Logs
NAS to NAS and Rsync
The NAS data can be backed up to a remote NAS or Rsync server using 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 to the remote server. The
default port number is 873. The login username must have read/write access to the remote
server and a 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 on it 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 on it 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 immediately replicate the
data or to specify a backup schedule.
7. Specify the following options for remote replication jobs by clicking "Options" and click "Apply".
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 Activate file compression: Allows file compression during the data transfer process. This option
is recommended for low bandwidth environments or remote replication over WAN.
o Perform incremental replication: When this option is enabled, after the first-time replication,
the NAS will only back up files that have been changed since the last backup. The files of the
same name, size, and modified time will not be copied again. Enabling this option is
recommended for replication jobs that will be executed multiple times in order to shorten the
backup time.
