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.

Nowadays there are a lot of NAS vendors; their NASes differ in number of disks, RAID levels, filesystem types and so on. ReclaiMe NAS recovery software works with various NAS devices by many vendors. The list includes:

  • QNAP
  • Synology
  • Buffalo LinkStation and TeraStation
  • Seagate BlackArmor
  • Iomega Storcenter
  • Thecus
  • Western Digital
  • LaCie
  • btrfs-based NAS servers
  • ...and many other

NAS recovery preparations

Before proceeding with NAS data recovery, you need to prepare the following:

  1. A PC 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 disk 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. disconnect/connect NAS disks
  3. Download and install ReclaiMe File Recovery software. Most NASes use so called md-raid or LVM drivers to handle an array. ReclaiMe is capable of parsing md-raid and LVM control structures if they are not too badly damaged.
  4. Select the NAS volume you need to recover and click Start. For the btrfs-based NASes like NETGEAR, the volume will be under the BTRFS section; for other NASes, look for it under the Linux md-raid or Linux LVM section.
  5. Select md-raid volume in ReclaiMe
  6. Wait until the ReclaiMe File Recovery starts to bring files and then check the quality of the recovery using the Preview .

  7. Purchase the license key and then copy the recovered data to the prepared storage device.

If you can't see the array in ReclaiMe File Recovery, then you need to recover RAID configuration first using ReclaiMe Free RAID Recovery software. When the parameters are determined, select "Run ReclaiMe to recover data" in ReclaiMe Free RAID Recovery tool and back here. Click here for detailed tutorial.
