Rich Backup Solutions of the Terramaster F2-423 2 Bay NAS

TOS can keep your valuable data protected with visual user interfaces and reliable storage solutions. With the integration of multiple backup apps, you will not have to worry about data loss caused by various circumstances.

Here in our Terramaster F2-423 2 Bay NAS Review, we will provide you with more details on these backup solutions.

Centralised backup is for virtual machines, employee PCs, and servers. It rapidly restores lost data after incidents.

Duple backup provides advanced data protection by creating backup files to a remote TNAS, cloud drive, or file server. Doing this allows the NAS to offer numerous backup versions, allowing you to retrieve files from multiple sources.

Another solution is Snapshot, which allows taking continuous shots of folders or iSCSI LUN. You will need to enable the snapshot schedule with advanced storage and optimised snapshot technologies via the BTRFS file system. When issues arise, the system can restore the last backup by rolling back to points in time, ensuring data protection.

The last backup solution is CloudSync, which backs up or synchronises the data in your FW-423 with the cloud drive. It improves the cloud data availability while providing several offsite backup versions like Duple backup. This feature also safeguards your data security.

The specifications of a NAS are essential for you to know if it can meet your needs. It will also help you prepare for the system requirements and other necessary elements when you purchase the product.

Hands-on with the Terramaster F2-423 2 Bay NAS

In this section, we will share our experience with the F2-423. We used it for a few weeks to see if it’s as good as claims. 

However, before we check how good (or not) it performed, we will discuss its TOS 5.0. 

TOS 5.0 is an operating system based on Linux. You can update it for free, and with the TNAS, you can utilise it for virtualisation applications. These apps have support for professional virtualised apps like VirtualBox and Docker.

This NAS from Terramaster uses the TOS version 4.2.39 out of the box. But the company recently released its TOS version 5.0, which is an update to the OS.

This operating system is for professional users. Terramaster optimised the storage structure and data interaction mode. Other than these, the company also added over 50 features and 600 enhancements to TOS. 

These new features meet more business requirements compared to the earlier versions. Also, Terramaster’s upgrade improves its response speed, ease of use, and security significantly. 

Our Terramaster F2-423 2 Bay NAS Review will also discuss how you can update TOS. Before testing the product, you must install the current version of TOS. 

To do this, download the file to your Linux or Windows box. From there, the TOS update process will ask for the location. You need to perform a factory reset to update the TOS but do not panic. 

The factory reset will not delete the data on the HDDs since the update procedure does not access your data. The TNAS will immediately restart and enter the initialisation page. 

If you cannot enter this page, it is best to use the TNAS PC to look for the TNAS again. Enter the TNAS IP address in the address bar from there. 

You can begin the installation of the latest TOS via manual installation. Then you can start checking your computer for the TOS 5.0 installation pack. 

After completing the system installation, it will automatically restart. After that, follow the instructions on the page to fulfil the administrator settings. 

When you finish that, TOS will require you to create a new superuser with admin rights. This step is vital since it will utilise the new name and password for logging in. 

Once you have installed the system, you must clear the browser cache. If not, some system pages will not display correctly. 

Generally, all the transfers were quick and seamless, regardless of the file type. We did not experience any huge issues, and everything went smoothly. There were no stutters, no lags, and no freezing. 

The Terramaster F2-423 performed amazingly and is ideal for high-load workflow with impressive levels of concurrent user access. It offers excellent storage and user-friendly user organisation for businesses. Also, it has backup and recovery solutions for everyone’s convenience. 

For its TOS platform, it may still not be as advanced as those from QNAP (the QTS) or Synology (DSM). The reason is that these brands provision most of their prices towards the software they offer. 

But as a standard set of services and tools, Terramaster’s TOS offers most of the standard and necessary applications. This offering goes with browser-based access to file & system management showcased in a glossy GUI. 

Simply put, the F2-424 is a remarkable product that we would recommend. 

Terramaster F2-423 2 Bay NAS Review Summary

The F2-423 from Terramaster is an impressive 2-bay NAS. It has a sleek design that suits most offices and gives an excellent user experience. Installing and setting up the NAS was seamless, and we also loved the user-friendly interface of the TOS. 

Configuring its settings was simple, so we enjoyed the different features available.

One of the best things about TOS is it does not require installing a specific application on your PC. It works independently like other operating systems on your LAN, such as Windows, macOS, Linux, and Raspberry Pi OS.

Aside from the software, we were satisfied with the fast transfer speeds of the NAS. It is an efficient solution for storing backups while keeping everything safe and protected. We also appreciate its versatility since you can use a 2.5Gbps LAN and add NVMe units for improved performance.

Also, the quiet operation was a bonus that made it more suitable for office environments.

With its unique features, efficient applications, and superior performance, we highly recommend the F2-423. It is one of the best NAS products on the market today.
