NAS Recovery

Although NAS devices are reliable storage, they still can fail. If you cannot get access to the data stored on a NAS, you can try to recover the data. Generally, NAS data recovery boils down to getting the disks from a NAS, connecting them to a PC, and extracting files using data recovery software. Depending on the damage, RAID recovery to determine the array parameters may be required as well.

Our NAS recovery software works with various NAS devices by many vendors. The list includes:

NAS recovery preparations

If your NAS has failed and you are going to recover data off it, then for sure you need:

  1. A computer running Windows to which you can connect all the NAS disks. It is possible to use SATA and USB ports in any combination. Although SATA is a more preferable option, not every computer has four or six SATA ports available. If possible, choose a more powerful computer because recovery of a large amount of data requires a lot of resources.
  2. Free space to which you will copy the recovered data from the NAS. It is impossible just to restore the NAS configuration onto the same disks so that the system revives. However, it is not required that a storage designated to hold the recovered data would be a single storage - you can place data onto the different disks or even copy it over the network.
  3. Plenty of time. Don't expect to get your data back quickly. Typically, the analysis of the array requires to read all the NAS disks thrice. Even if you manage not to mistake and do NAS recovery correctly from beginning to end, nevertheless it takes several days for recovery to complete. On the bright side, the majority of the time a computer works on its own; therefore, you don't need to actually be at the computer all the time.

NAS data recovery using ReclaiMe

  1. Get the disks out of the NAS and connect them to the PC. Don't forget to turn off the power and pull the plug out of the wall socket when disconnecting and connecting the disks. When you take the disks out of the NAS, label all of them according to which bay they belong to. These labels will help you to put it all back together in the same way if needed. If Windows on the PC to which you connect the disks to asks you to "Initialize disks" or even "Format" them, don't.
  2. Download and install ReclaiMe File Recovery software. Most NASes use so called md-raid to handle an array. ReclaiMe is capable of parsing md-raid control structures if they are not too badly damaged.

  3. Select the NAS volume you need to recover and click Start. Naturally, it will be under the "Linux MD RAID" or “Linux LVM” section.
  4. Wait until the software completes the analysis and then copy the recovered data to the prepared place.

If you can't see the array in ReclaiMe, then download ReclaiMe Free RAID Recovery software and determine the array configuration parameters. Note that to recover the RAID configuration you need to know what RAID type was used in your NAS. When the parameters are determined, click "Run ReclaiMe to recover data" in ReclaiMe Free RAID Recovery tool and back here.
