Network-Attached Storage (NAS)

Network-Attached Storage

What is Network-Attached Storage?

Network-attached storage often abbreviated NAS, is a backup device that plugs into a router. It allows multiple computers to backup and retrieves data. I offer and set up Network-attached storage devices for home users and small businesses.

In other words, it is a specialized computer that is built for dedicated file storage using centralized disk capacity. Users on a local area network (LAN) access the shared storage via a hardwired Ethernet connection or by wireless (Wifi). A NAS does not have a keyboard or monitor. They and are managed from a local or internet-based browser utility.

Data backup solutions are now available.


What is Network-Attached Storage used for?

A NAS is connected to a network and allows users to backup data, and offer centralized file sharing for documents. Flexible shared folder and user quota system provide comprehensive quota control on all user accounts and shared folders for collaborating to make sharing more effective including remote access. On more robust units you can run applications such as Virtual Machines. Some units are set up to act as a 4K Multimedia Server.


The key benefits of network-attached storage are:

  • A NAS offers fast backups of large data since it is a local device. While cloud storage is extremely useful, they have a major problem in that they are slow this is a problem particularly if you have a large amount of data or if you are trying to run one or more full system images per day. A local NAS allows for faster reading and writing of data.
  • Data loss is less likely to occur with a properly configures and maintenance NAS. The goal is to have the hard drives set up in RAID to make sure that if an individual disk fails it does not result in loss of data. With the data on more than one drive on the NAS, your computer, and cloud storage you are covered using the 3-2-1 backup rule.
  • You can schedule backups. Since all computers are connected wired or by wireless Wifi and the unit is always on, you can schedule backups. Having backups not scheduled is a major reason external hard drives do not work as solid backup solutions.
  • Backing up multiple computers is simple. I frequently set up solutions for 2-20 computers all to backup and utilize the same unit.
  • Making full system images (or cloning) allows us to get an exact clone of your computer. This offers data protections and captures your operating system, all programs, software, and settings exactly as it currently exists. You have the assurance your whole computer is securely backed up in an easily recovered single file.
  • Entry-level NAS systems are fairly inexpensive. Starter units can be as small as a two-bay unit with two 1TB drives in a mirrored configuration.  They can be purchased for more robust solutions and larger data requirements (4TB, 8TB, 16TB, 32TB, or more). This enables them to be set up for home users with multiple desktops and laptop computers or deployed on Small and Medium Business (SMB) networks easily.
  • Long-term costs are fairly low when you factor in the initial purchase cost, most units last for 4-5 years with maintenance. There is not an ongoing fee every month or year like cloud storage.
  • Expansion is available and more storage can be added to large bay units (4-bay, 8-bay, 6-bay- 12-bay). A unit with free space can be scaled to add additional disks to increase the amount of total storage capacity. Certain units allow for storage expansion with additional compatible expansion units.
  • Software such as DiskStation Manager (DSM) which is included with Synology’s solutions is included and offers an intuitive web-based operating system designed to help you manage your digital assets.
  • They normally require less energy (than a server) and take up a smaller footprint in your home or office. For instance many 4-bay units are 8.78″ x 7.83″ x 6.54“.


There are only a few real disadvantages to network-attached storage, and they are as follows:

  • Network-Attached Storage is an onsite data backup. In the case of any natural disaster, theft, or fire you could have the whole unit and the drives destroyed losing all data. Certain precautions can be taken for human error or viruses such as ransomware, but overall it is a good idea to also behave data off-site.
  • They do require I.T. knowledge (data storage, data backup, computer networks, operating systems, Linux, security) to effectively setup them up and maintain.
  • Similarly, to requiring professional knowledge to implement and maintain them – most problems (or disadvantages) come from lack of knowledge or improper implementations. In other words, the majority of issues I have found are lack of planning for future needs (selecting the wrong unit), not having maintenance performed, not diligently checking or testing backups, improper management of space, having poor infrastructure, or having network issues.


I offer NAS (Network Attached Storage) solutions from:

  • Synology includes professional solutions for business, including DiskStation J Series, Value Series, Plus Series, FS Series, and SX Series.
  • Buffalo who’s LinkStation NAS devices are targeted at small businesses and individuals, and TeraStation which are built to provide larger storage solutions for today’s and tomorrow’s business demands.
