NAS Technology and Data Recovery

What are the challenges?

Modern NAS devices offer users a wide array of features and technology at an affordable price. The challenge from a data recovery perspective is that as more and more features are added to a device, the complexity of work required to recover the data if something goes wrong often increases as well. In many cases, a user might utilize a function available on a NAS without fully understanding how that technology impacts the data ultimately stored on the drives.

Ontrack has invested hundreds of hours of development time to ensure we stay ahead of the game and can recover data from even the most complex NAS systems.

Emergency Tips

What to do if you experience a NAS drive failure?

  • If you hear unusual noises, you should shut down the system immediately
  • Validate your backup before replacing or updating hardware or software
  • Do not use RAID recovery software if there is a possibility of a hardware failure
  • Do not defrag possibly damaged drives
  • Do not rebuild and/or reinstall the original system
  • Do not restore a backup to the same volume / drives
  • Call Ontrack to find the fastest solution for your NAS recovery.
