NSA-2401 Support Note Key applications This support note will be supplemental document for some of new features in NSA-2401. The more details of meaning of options can be found in online help and user guide. 1. How to search my NSA-2401 In the beginning, the default IP address of LAN1 is 192.168.1.3, and LAN2 is 192.168.100.3. Also, username is “admin” and default password is “1234”. However, user can change the default username and password later.
NSA-2401 Support Note 1.2 Configure network First, users can configure the IP address of specific NSA-2401 by clicking the “Config ” icon. There are DHCP and static IP options and dynamic and static DNS for network setting of NSA-2401. Hence, users can use this to change the default IP address. 1.3 Login into admin There is another convenient option for users to log into the web-based GUI of NSA-2401. By clicking the “Admin ” icon and system will open login page of NSA-2401 in web browser.
NSA-2401 Support Note 2. Volume Encryption In NSA-2401, users can encrypt individual internal volumes once they create them. There are two ways to protect their data volume. One is set the password for individual volume(s); the other is to create an USB key. Please pay attention to make multiple copies for their password and\or USB keys. First, users can create their internal volume by selecting Storage> Internal Storage> Create. Afterwards, users need to activate the “Encrypted” option.
NSA-2401 Support Note In this example, we select “USB key” as encryption method. Hence, users need to plug into his USB flash drive in NSA-2401 in advance. Please notice that this USB will be formatted and stored for the encrypted key ONLY. This USB key should be dedicated as the USB key ONLY. Users can not use the USB flash drive to store other files anymore. Note: z Please make two or more USB keys for your volume. z It is very important to keep your password and USB key(s) in one secure location.
NSA-2401 Support Note 3. Sharing 3.1 ACL feature In NSA-2401, there is a new feature for system administrator to control users privilege in accessing specific file(s). ACL (Access Control List) is the main function to achieve the file management for every user. First, users need to create a share folder and make it as public, then system administrator can assign individual files access right. The following figure shows that one folder named “Test” created for public usage.
NSA-2401 Support Note Next, you can see the public share folder list as following. Click Sharing > Shares, select a share, and click ACL Properties screen to open the Access Control List (ACL) screen. Use this screen to display and configure ACL settings. The ACL defines read/write permissions for specific files and/or folders. Next, administrator chooses a file to set ACL for the assigned file.
NSA-2401 Support Note After the above ACL setting, one ACL rule for the given file is implemented. As for the access right at EVERYONE & ANONYMOUS share Access, with an EVERYONE access right, you still need to log in. Every local user with an account on the NSA can access this share using their username and password. However, users with accounts on a domain server cannot access shares with EVERYONE access rights. EVERYONE has every local user as a member. It does NOT include domain users.
NSA-2401 Support Note 4. Protection There are two backup functions in NSA-2401. One is built in NSA-2401 and the other is executed by Genie Backup software (GBM). Hence, in our design, users can create data backups to another volume, an external USB disk drive, or a computer or another NSA over the network. The above figure shows that there are three ways to backup data in users’ NSA by using the backup function in NSA. I. NSA to remote NSA II. NSA to external USB hard drive disk III.
NSA-2401 Support Note After clicking the add icon, system will guide users to configure this task step-by-step. IN first step, users need to set job name and its description. Additionally, users can set the type of backup to be full copy of the data or incremental copy of users’ data. Users can make copy to another NSA-2401. Please notice that the actions of synchronization in backup type, there are two types of options: Publish and Mirror.
NSA-2401 Support Note In mirror method of synchronization, the data in NSA-A will be copied to NSA-B and the original files in NSA-B will be deleted since the mirror mechanism. In other words, the original data of NSA-B will be erased and keep the data be identical as NSA-A. Please make sure which kind of synchronization you like before run the backup task. The above scenarios can help system administrator to do backup in different locations to prevent the single location failure.
NSA-2401 Support Note In step 3, there are options for compression type, encryption type and purge policy for users to manage. In purge policy, users can decide how many backup in history would be kept in system. Furthermore, users can decide the time to start and frequency of backup. The backup can be scheduled as hourly, daily, weekly or monthly. After all above steps, the new backup schedule is implemented. Users can check the details of backup task listed in the menu.
NSA-2401 Support Note 4.2 Backup Application NSA-2401 also provides another windows backup application, Genie Backup Manager (GBM). It is bundled with each NSA Storage unit. Users can have unlimited client license but have only one server license. This application is used for backup user’s data in their PC to NSA-2401. In practice, users can still use GBM to backup specific data of NSA to user’s PC but not all volume. Regarding to the GBM software, users can find the setting in protection >backup software.
NSA-2401 Support Note 4.2.1 GBM Lite software Users can find the GBM Lite software in the CD when they purchase the ZyXEL NSA-2401. After a few minutes installation, user can find the serial number on the bottom of machine and then finish the installation of GBM Lite software.
NSA-2401 Support Note 4.2.1.1 Create Backup Task After installation, users can find the program group in their PC and just click the icon to run the GBM software. It is very easy to configure your backup task by using GBM. There will be step-by-step wizard to guide your own backup task. By selecting the backup function to start the configuration. Next, users can create a new backup task including name and description.
NSA-2401 Support Note Then, users can choose the method of backup by local area network or by FTP method. In this example, we choose to backup from PC to NSA-2401 through LAN and store the backup file in the folder of CSO.
NSA-2401 Support Note Next, users should choose which folder(s) will be made a copy in this backup task. Next, there are options for different type of backup, compression and security for users. Please make sure which one is better for your application. Furthermore, full backup means that copy all the data users assign no matter data is old or new added. But, in incremental method, backup will only made the new added files.
NSA-2401 Support Note As for the security function, we suggest that administrator apply the encryption for your backup file, especially in the remote backup scenario. There are three types of AES encryption in 128-bit, 192-bit and 256-bit. These numbers refer to the size of the encryption keys that are used to encrypt the data; the higher the number the stronger the encryption, at the expense of being slightly slower.
NSA-2401 Support Note After the above procedures, one scheduled task is implemented. 4.2.1.2 Schedule Backup Task Users can decide the backup time and frequency when they set a task. In the following figure, users can set backup task as weekly, monthly or other situation based on customer need.
NSA-2401 Support Note After the above procedures, one scheduled task is implemented. 4.2.1.3 Restore lost data GBM Lite also provides friendly way to restore data from backup file(s). Users just need to click the store icon and then choose the specific file(s) and\ or folder(s) to be restored. Then, restore procedure will be finished quickly.
NSA-2401 Support Note After deciding to restore your data, you need to choose which backup file will be your source to restore if you have two more backup files. IN this example, there is only one backup file.
NSA-2401 Support Note Afterwards, users can select which file, folder or all the data to be restored. Finally, GBM Lite will run the restore procedure after you double confirm the restore action.
NSA-2401 Support Note 4.2.2 GBM Server software The benefit of using GBM server is that users can backup their SQL server and Exchange server to NSA-2401. The backup procedure is similar with the GBM Lite. However, the GBM Server needs to be installed in the server which users want to run backup process. For examples, SQL server or Exchange server. Then, the GBM Server can run the regular backup task(s). 4.
NSA-2401 Support Note If the “Snapshot Image Access” is set to “Allow Only Admin”, then normal users do not have privilege to the snapshot. Only admin has the right to access the snapshot. If the “Snapshot Image Access” is set to “User Share Permissions”, then normal users have privilege to access the share folder inside the snapshot image. 5. Networking 5.1 Dual Gigabit Ethernet Ports Support NSA-2401 provides dual Gigabit Ethernet (GbE) ports for deploying various scenarios.
NSA-2401 Support Note 5.1.1 Standalone Mode In the scenario of “Stand Alone,” LAN1 and LAN2 each use a unique IP address. These IP addresses are independent of each other. For example, one LAN port can be accessed from Internet users; the other can be used for Intranet users. System administrator does not need another switch to deploy if the company topology is simple enough. The configuration is similar the usual network setting, but one more LAN port.
NSA-2401 Support Note 5.1.2 Fault tolerance Mode In the scenario of “Fault Tolerance,” LAN2 serves as a backup (fail-over) for the LAN1. Hence, both Gigabit Ethernet interfaces are connected to the same subnet. This application can prevent the single link failure and provide more reliable network environment. In the configuration, there is only one IP address. If LAN1 loses its connection, LAN2 takes over LAN1's IP address and traffic.
NSA-2401 Support Note 5.1.3 Load Balancing Mode With the application of “Load Balancing,” NSA-2401 will distribute the traffic load across LAN1 and LAN2. If the setting of LAN1 and LAN2 are on the same subnet with the same IP address, NSA-2401 also includes backup functionality (fault tolerance). Here, we suggest users to use DHCP if two LAN ports are located in different subnet.
NSA-2401 Support Note The algorithm of load balancing use hash function to allocate the traffic. Hence, the best scenario of deploying NSA-2401 with load balancing is inside the LAN. NSA-2401 will use source MAC address to distribute traffic. In other words, the traffic might be use specific port to forward the Internet traffic with the gateway topology since the incoming requests will be forwarded by gateway and gateway MAC will be used in the hash function of load balancing.
NSA-2401 Support Note 6. Power management NSA-2401 provides users to do power management. To schedule the power on/off regularly, users can use this function to shut down and/or reboot their NSA-2401. 4.1 Power control schedule First, enable the “Power Control Schedule” in Maintenance\Power Management NSA-2401 provides three actions, “Power On, Power Off and Reboot”, to assign in schedule list.
NSA-2401 Support Note In the following example, there are two schedules in the control schedule list. First rule is to set NSA-2401 regularly power off on 23:00 every Fridays for future 52 weeks. The second rule is to set NSA-2401 power on 00:00 every weekday.
NSA-2401 Support Note 4.2.1 Keep Former Status In this function, there are three options to be set in NSA-2401. The first one is ‘Keep Former Status.’ In other words, NSA-2401 will back to the status before power outage. For example, NSA-2401 will keep power off if it is power off before power shortage. 4.2.2 Always Power On The second one is ‘Always Power On’ NSA-2401 will keep the status of «power on even it encounters power shortage.
NSA-2401 Support Note 4.2.3 Always Power Off The final one is ‘Always Power Off.’ NSA-2401 will keep the status of ‘ power off’ even it encounters power shortage. For example, NSA-2401 will always keep power off if any power outage happens.
NSA-2401 Support Note FAQ 1. What is RAID? RAID stands for Redundant Array of Inexpensive Disks. It takes two or more hard disks to achieve greater levels of performance, reliability and/or larger volume of data size. 2. Which kind of RAID is supported in NSA-2401\NSA-2400? NSA-2401 support JBOD, RAID 0, RAID 1, RAID 5 and RAID 10. 3. How many hard drive disk(s) do users need to implement RAID5 in NSA-2401? To achieve RAID 5 in NSA-2401, the minimum HDD is three. 4.
NSA-2401 Support Note 7. What is “Jambo frame?” Originally, the MTU size in Ethernet is 1518 bytes. However, this will be time consuming while users need transfer large volume of data. Hence, the bigger size of frame exceeding 1518-byte per Ethernet packet is introduced. The Jambo frame size can be extended to 9000 byte but also depends on related network devices. 8.
NSA-2401 Support Note 11. What is snapshot? A snapshot represents a frozen image of a volume. The source of a snapshot is called an "original." When a snapshot is created, it looks exactly like the original at that point in time. As changes are made to the original, the snapshot remains the same and looks exactly like the original at the time the snapshot was created. Hence, the function of snapshot is very useful and important for data protection. 12.
NSA-2401 Support Note 16. Is there any way to recover the snapshot if the damaged disk array contains the snapshot(s)? No, the snapshots are lost and cannot be recovered if the disk array containing the snapshots fails. 17. What is the button marked as “COPY” in the front panel of NSA-2401? The copy button is a handy hardware button on the front panel of the NSA-2401. Users can use it to copy files between a USB flash drive or externally connected hard disk and a share in the NSA.
NSA-2401 Support Note 19. What is the difference between "Scan" and "Repair" on NSA-2401? "Scan" is a defragment tool on NSA-2401, it is similar to the defragmentation tool on Windows PC. If you have the NSA automatically attempt to repair any damaged files it finds during the scan, be careful not to cancel the scan as you may lose data. "Repair" is used to resynchronize a RAID.
NSA-2401 Support Note 24. How to use the reset button in NSA-2401? NSA-2401 Reset button function: 1. One beep (press 2 seconds): Reset admin password & ip setting 2. Three beep (press 10 seconds): Reset to factory setting and reboot 25. Does NSA-2400 support NFS protocol? NSA-2401 does support NFS network protocol. 26.
NSA-2401 Support Note system will delete the oldest or the bigger snapshot images when you restart the job. This is assuming that you set the maximum number of snapshots to ten. 31. How to download diagnose information? It would be better to quickly resolve your difficulty in your system if you could provide your detail system diagnose information to ZyXEL. There is one system diagnose file recorded in NSA-2401. Administrator can retrieve this information by the following steps: 1.
