Data loss and recovery process

It is very important that you learn about data loss in order to have a clear understanding of data recovery. If the term data loss is not understood by you properly, it will only lead to unsuccessful attempts at data recovery. Data loss is when you are unable to access your storage device and hence cannot locate your files on that device. The most common reason for data loss is due to the storage device getting corrupted – physically and logically.

You must have heard the term data recovery. Now, what is this data recovery process? It is the way in which you retrieve lost data. We are living in the digital era. No wonder files and albums have become obsolete and given way to hard drives that store all your important files and photos. But with constant advancement of technology, even the USBs and external drives are taking a back seat. The new intervention in the field of data storage and recovery is network attached storage (NAS).

QNAP RAID recoveryis one such network attached storage tool. QNAP RAID recovery uses RAID technology to give access to data storage devices in a home or corporate setup. QNAP RAID recoverytechnology uses the traditional RAID arrays. The QNAP RAID recoveryis a part of QNAP NAS that offers cutting-edge technology along with expansions units. This makes QNAP RAID recoverymore efficient as they can not only improve the current server capabilities but can also add new ones.

What types of RAID are used in QNAP NAS?

As QNAP RAID recovery is part of QNAP NAS technology it uses various types of RAID technologies that give each QNAP RAID recovery a unique feature. Some of the types of QNAP RAID recovery technology are:

  • Single: This type of RAID has zero disk failure tolerance. The capacity of the RAID is the size of one disk. It does not provide any performance benefit. This type can be selected in case you have the option of selecting only one disk and you also have a data backup plan in place.
  • JBOD: The full form of JBOD is just a bunch of disks. This type of RAID has zero disk failure tolerance.In this type, there is a combination of disks that are appended together in a linear fashion. QTS operating system writes data on one disk and when it is full, it moves to another disk.
  • RAID 0: In RAID 0 more than one diskis combined together using a process called ‘striping’. This type of RAID offers the fastest speed of reading and writing a disk. The entire disk capacity can be used in this type. However, even in this type there is no plan to protect the data and should be used only when there is a data backup plan.
  • RAID 1: This is a slightly advanced RAID type with one disk failure tolerance. The size of the disk is divided by two and an identical version of the data is stored in two disks. If any one of the disks fails, still you can access data from another disk.
