3 Product Models Covered by This Document This document applies to the following product models: SNC NAS 200 SNC NAS 500 SNC NAS 800 SNC NAS 850/850-1/850-2 SNC NAS 1100 SNC NAS 1310 SNC NAS 1510/1510-1/ For more information regarding individual product models, please visit 3

4 SNC NAS Unified Storage Systems SNC NAS offers a complete solution for data storage, file sharing and data backup ideal for SMBs and SOHO users. The SNC NAS systems consolidate server and storage requirements in a single device, and support a wide array of protocols to ensure data can be shared by all workstations in the office. System resources on SNC NAS can be optimized with data deduplication, while diverse protection and backup features protect valuable data assets.

5 Setting up Remote Replication on SNC NAS Remote replication via the rsync protocol allows users to create an identical backup copy of an SNC NAS system (source) in a target device located at a physically distant place. When system failure occurs, the target can swiftly restore the data and network services to the previous state. The storage space of the target device (could be another SNC NAS system) must be equal to or larger than that of the source SNC NAS system. Data replication is carried in asynchronous mode, which updates the data periodically in bulk (only the differentials will be copied), thus preserving system resource for data transactions. To set up remote replication, follow the steps highlighted below. Step 1: Preparing the environment The following devices should be connected to the same network: The source SNC NAS hardware (where the configuration will occur) The target SNC NAS hardware (if data is replicated to another SNC NAS system) Third-party networked device (if data is replicated to such a device) Target Device Requirements for Remote Replication The capacity of the target SNC NAS or third-party device must be equal to or larger than the source SNC NAS. The target device must be compatible with rsync, an industrystandard application for file synchronization. Before configuring remote replication parameters, the following information of the target device should be obtained: IP address Login user name Password 5

6 Step 2: Creating a remote replication pair In the SNC NAS UI, go to the Backup > Remote Replication menu of the source SNC NAS. Click the Add button. The remote replication settings window will appear. 6

7 Backup Source: Select backup source directory; click browse to look for a specific folder. Note that users cannot select an entire storage pool. If the target is a 3rd party device, you cannot select All Shared Folders or Home Directory. You can only select a specific folder. Backup Target: Specify the IP address, username, password and directory of the target device. Choose a NAS system or a 3rd party device (Rsync Server) as the target. If you have chosen a 3rd party device, do not change the port number 873 unless you need to. 873 is the default port number used for the rsync Daemon mode for the remote replication conducted between the NAS and a 3rd party device. Encryption: Choose to enable or disable data encryption during the replication process to add extra layer of protection. (This option is not available if an Rsync server has been chosen as the target.) Schedule the remote replication task. Backup daily: Replication will occur on a daily basis at the specified time. Backup weekly: Replication will occur on a weekly basis at the specified date and time. Customize: Allows configuring a more complex schedule. See the next step for details. 7

8 Step 3: Customizing the Schedule (if not applicable, skip to Step 4). When the Customize schedule option is chosen, the snapshot schedule setting window will appear. You may optionally add a short description of the schedule. Description: (Optional) Allows you to enter a short description of theschedule. Start Time: Specifies when the snapshot process will take place. Daily: The snapshot will be taken every day at the specified time. Weekly: The snapshot will be taken on a weekly basis on the selected (checked) days of the week, at the specified time. Monthly: The snapshot will be taken on a monthly basis on the selected days of the month, at the specified time. 1. Choose the day of the month: 1st 31st date of the month or the 1st 4th Monday Friday. 2. Select the months the snapshots will be taken by clicking Select Month. By default, all months are selected. Advanced Schedule Settings Click Advanced to customize the schedule further. 8

9 To set the Start Date and End Date, click in the column and select the data from a calendar popup. The Repeat option allows you to configure the duration of the backup task. Every: A snapshot will be taken at the specified interval. Until: Specifies when taking snapshots will complete. If Time is selected, snapshots will until the specified moment. If Duration is selected, spapshots will be taken for the specified period of time. Click Next to view the summary of your backup job. Click Back to modify or OK to confirm. 9

10 Step 4: Completing the Configuration The newly created remote replication task will be shown in the list. Click Edit to change the configurations. Configurations can be changed in this window. Click Options for more settings. Configure the optional settings and click OK to go back to the previous menu. Compress file data: Reduces the data size using LZJB, a losslesscompression algorithm. Stop network file service while replicating: Additional data protection by pausing network file transactions while replication task is ongoing. Delete extra files on remote destination: Removes unrelated files in the target directory to create room and to clear up clutters. Handle sparse files efficiently: Utilize file allocation effectively for small files. In the list, click the Execute button to start remote replication. 10
