What is NFS data storage?
Back in the 1980s, Sun Microsystems developed a distributed file system protocol called NFS. It is a kind of storage, which allows the user to access files on a personal computer through the network. This can be compared with access to local storage. NFS is based on the Open Network Remote Procedure Call system and has several versions; for example, the latest was released in 2016 under the name NFS 4.2. In other words, NFS accesses a drive through a network.
Other storage systems include EXT or VMFS, which access files from the disk image.
How does it work?
Everything here is based on the principle of server and client interaction using appropriate protocols between them.
Thanks to NFS, a computer gives simultaneous access to its data to any other computers with one single network.
For example, one network of computers in an office has access to this storage.
When working with the NFS file system, read and write operations are actually performed not by the client, but by the server, which executes requests, retrieves and saves data, and changes file metadata (such as access rights or file modification time).
Benefits of the NFS
NFS has been improving for several decades, so there are many advantages, especially for corporate clients.
NFS has quite interesting host authentication. You need an IP address only for the connection to another service.
For example, the infrastructure for NFS has a low cost, and this is due to the fact that it can work on ordinary Ethernet devices.
NFS hides the implementation and type of server file system and thereby ensures confidentiality and security.
Such a file system is presented in the same way as a local storage device.
Here, centralized management takes place and you do not have to update new files yourself.
How to repair NFS data with VMFS Recovery
If NFS fails, you need to restore EXT (2,3,4), find the image files on it and extract it from them already. The disk images themselves can be anything: NTFS, EXT, VMFS, ZFS, or XFS. Since VMFS is the most common, use VMFS Recovery. This application allows NFS data recovery from any inaccessible or damaged disks. The whole recovery process is almost automatic, thanks to the Recovery Wizard.
Recovered files and folders are exported to local or remote locations (including FTP). Any virtual disk can be converted to local for access; for example, in Windows Explorer. Another useful feature is Unicode support. Instructions for using DiskInternals VMFS Recovery are included below.
Initially, you will need to install the application on the computer. You can download it from the DiskInternals website.
Note: the program supports Windows Vista, 7, 8, and 10, as well as Windows Server 2003-2019.
After starting the application, it is necessary to indicate which drive will be recovered.
Then the Wizard will offer several application modes:
- fast recovery mode
- full recovery mode
Scanning will follow immediately and take a lot of time. Then all found data will be available for viewing.
If everything suits you, it's time to buy a license. You will be able to export all found or specific files at your discretion.
