A NAS device is a file-level computer data storage server that is connected to a network where client computers can have quick access to the files it contains. NAS devices are designed in a robust way that enables them to run 24/7. These devices also provide faster file access to client PCs they are connected to the same network with.
NAS devices are also designed to work for many years before they require any replacement. However, if you don’t take good care of them, they can easily fail within a short period of time. If you want to increase the lifetime and maintain the good performance of your NAS device, this article is for you. We are going to share with you some tips on how you reduce the risk of failure and data loss of your NAS device. Here we go
- Power your NAS device with an interrupted power supply
One of the major causes of failure in NAS devices is instability in the power the device receives. For instance, a sharp change in the voltage of the power supply may lead to the failure of some internal components of the NAS device. To mitigate this, avoid connecting your NAS device directly to Grid power. Install an uninterrupted power supply system in between so that it stabilizes the power before it gets to the NAS device.
- Put limitations on data access rights
If you give freedom to everyone connected to the NAS device network to add and remove the data they wish, you will likely lose lots of data due to a few irresponsible people on the network. To avoid such scenarios, always put strict rules regarding who can add and remove data from the NAS device. Most of the server operating systems have the option of setting data access rules on your NAS device. So, always take advantage of them.
- Have your data backed up automatically
You can not have all the data on your server stored on one device. It is important to create several backups of the most important data that you would need in case the main NAS system fails. Most of the NAS devices support the option of automatically backing up the important data of the device. So take advantage of this option because it may save you one day.
- Make sure you check on the data backups regularly
Just like your main NAS device, the devices you use to backup your data are also equally vulnerable. So, you should check on them regularly to make sure all the backed-up data they are storing is safe. You should also make sure the backup system is not on the same power supply and also not in the same room as the main NAS device. Separating them will eliminate the risk of losing both devices due to a fault in the power supply or even something unexpected like a fire outbreak.
- Make sure you choose the right RAID level for the hard drive in your NAS system
The RAID level you choose is highly significant as far as the safety of your data is concerned. So, always make sure you choose a RAID that will keep all the data on your NAS device secure without affecting the performance of the client devices trying to access the system. There are several RAID levels that you can choose from based on the main objective of your NAS
It is always a good practice to choose a RAID level that has a good balance between performance and data safety. It may require installing a more robust infrastructure to have a system that is safe and high performing. But in the long run, this investment will pay off. So, don’t be tempted to save money by compromising data safety.
- You may also have to document the system information of your NAS device
This may not be of immediate use, but in the event of failure, the system information of the NAS device will be so crucial. So, make sure you write somewhere safe the file systems used in the device, controller version, BIOS version, and any other system information that you find relevant.
- Use the standard hard disks that are recommended for NAS systems
NAS devices can accommodate several hard disks. The space you need on the device is what will determine the number of disks you need to install. However, you shouldn’t be tempted to install any type of hard disk because not all hard disks will be compatible with your NAS system. You may have to inquire from the manufacturer of your NAS device about the disks they recommend.
This information can also be found in the user manuals of your device or the website of the manufacturer of your NAS system.
- Avoid panicking in the event of failure
If you realize that your NAS device has failed, it is always good to stay calm and think of the best possible ways you can recover the data that has been lost. You should also not attempt to do the recovery yourself if you don’t have enough expertise in data recovery. This is because you may end up destroying all the files which may make them unrecoverable.
If a failure occurs, we recommend you bring on board a G-Raid data recovery expert to help you determine the best possible way to recover as much data a possible.
NAS devices are very important for companies that deal with huge amounts of data. The data normally stored on these devices is important in running the day to day operations of the company. To avoid scenarios of paralyzing operations, it is important to make the right decisions while installing NAS systems and during maintenance.
The installation and maintenance choices you make are what will determine how safe the data stored on the NAS devices will be. So, make sure you don’t compromise the safety and performance of your NAS system simply because you want to save some money because this won’t be worth it in the long run.
