NAS Data Recovery

Most consumer-grade and home-office NAS units have one or two bays, while models designed for the office have four or more. But that’s not an absolute guideline, especially now that newer NAS devices are showing up with support for 2.5-inch laptop-style drives, both platter-based and solid state.

The beauty of a NAS device is that it can use some version of a technology called Redundant Array of Independent Disks (RAID). This tech allows the software that manages the NAS devices to distribute and duplicate the data it stores across multiple hard disks.

Home NAS

Most home based NAS drives will have  two bays, which means that you can set them up as RAID 1. In this scenario, the second drive is a mirror of the first, so if one drive fails completely all your data is safe on the other. You can then replace the faulty disk, and rebuild the RAID array.

Office NAS

A typical business scenario might be sharing access to Office files, like spreadsheets and Word documents, with your coworkers and perhaps backing up select office devices on a regular basis. All of that is relatively simple for a NAS. Additional layers of data security and serving files to a relatively large number of users is typically where businesses need to be careful about NAS storage.

Common NAS Failures

As well as the failure of an individual drive NAS devices are also prone to Power surge causing physical or logical corruption. Virus attack. Data could not be viewed due to security system failure. Loss of network shared volume due to accidental reformat or loss of original configuration.
