Network-attached Storage (NAS) is simply a data storage server that is devoted to file sharing within a computer network. NAS servers deliver users with innovative features and proficiencies, and support high data storage capacity, even more than 1000 TB. NAS server simplifies storing, sharing, and accessing files kept on NAS drive(s) by numerous users connected to the server. The enterprise-level NAS servers support RAID arrangements that offer high performance and disk redundancy. NAS devices can also be equipped for backing up data, streaming and storing media, surveillance system, etc. These NAS devices can even host business applications that sustain emailing system, payroll, data logging, and much more. It stores important data and information and a failure in the data storage may prove hazardous.
The Need for NAS:
For enterprises and companies that stores a huge chunk of data on its server, opting for NAS seems a bright and practical solution. Since storing data on NAS acts as a centralised process to access your data irrespective of your location. Moving data manually is not a safe process and you might end up losing important data or there might be some mismanagement of data. If your data is centralised, then it can be accessible from anywhere and thats why NAS steps in to cater the request of SMBs.
What Causes NAS Failure?
1.Power outage:
Power failure and voltage instabilities may result in NAS failure. These factors can avert the disk from integrating to RAID.
2. User error:
User blunder such as inadvertent deletion of files and folder can result in NAS or RAID data loss.
3. Overheating:
Overheating can source NAS failure. It is strongly advised to store the device under optimum temperature.
4. Manual faults:
When one of the drives fail, it puts a load on the residual drives for processing. This occasionally causes NAS failure.
5. Defective NAS controllers:
Corrupt firmware, operating systems errors, incomplete configuration etc. can also end up resulting in NAS errors.
How to Avoid NAS Data Loss?
A little attentiveness can avert data loss and in efficacious NAS data recovery. To alleviate the risk of data loss, heres what you can do:
- It is prudent to frequently create automatic backups.
- As numerous users share the network, the access rights should be specific.
- Depending on the necessity always pick the correct RAID setup. For example, RAID 0 allows quicker data access but does not deliver data security. On the other hand, RAID 5 is preferable in terms of data security.
- Always test protracted NAS as unfinished operations can result in data loss
- Implement accurate documentation
At times, a NAS drive fails due to any unanticipated reason, ensuing in loss of significant personal or business data. If youve lost data from NAS, it is strongly advised to not try any hit-and-trial approaches such as repairing the failed drive, recovering data on your own, etc. This can worsen the situation and end up in permanent data loss. Thus, its best to reach out to a Asustor data recovery services provider who can recover your data with security and privacy.
