Better to purchase hard disks from different batches of production, as this can reduce any production related errors. The most reliable hard disks are the ones that have fast access time, the ability to run continuously, and a large cache. Make a wise Investment – While buying a hard disk for storing data, always pay attention to its quality.Correct documentation plays an important role in data recovery and data compliance. The important details that are most commonly forgotten include controller version, BIOS version and the file systems used. Proper Documentation – Every administrator should document the used NAS system.Most likely, a complete failure and finally, data loss can occur due to incorrect expansion. Also, the extended NAS solutions should be tested at the same time by experienced personnel before doing the final setup and operation. Check Backup functionality – The Backups should be regularly checked and tested for their functionality as an inaccessible or incomplete data is not worth anything.
Also, while storing the data in an external location, it should be encrypted. If the data is spatially separated then much more security can be achieved. So, it is highly recommended to take periodical back-up of all the important data on some other storage media like USB hard drives. Automatic Backup – Though NAS system provides many advantages but still absolute data security is not there.Often the data is deleted because a user doesn’t know if the data is needed by another user. Control the access rights – In case the network storage is shared between more than two users, then it should be very clear who can access what data.To help you prepare against such scenarios, we have complied together some useful tips to prevent the risk of data loss: A little cautiousness the enormously increase the data security. The above failures show that there are many reasons that can cause data loss, even in a NAS system.

Professional data recovery services such as Datadoctor has the tools and capabilities to properly clean and restore data successfully even from worst data loss situations. In such cases a system rebuild will need expertise knowledge and the capability to decontaminate and thoroughly clean the hardware – then the data can be restored through a logical rebuild. Natural Disasters – Water damage, fire damage or other natural disasters can cause destruction of NAS systems in seconds.Operating system errors or Firmware can also cause the loss of information by overwriting the memory configuration. Defective NAS controllers – These can be resulted due to faulty rebuilds or reorganizations, causing data loss.
This may lead to further stress on the system causing further disk damage, which often ends in a complete system failure. As soon as a RAID/NAS system is used in state where hard disk has failed (degraded state), the left hard disks should compensate for the failure.
This causes hard disk overheating and system failure which may lead to data loss in some cases.
