How does data loss on NAS systems / RAID arrays occur?

Each data loss has its own story, but there are common scenarios that require data recovery from network storage.

  • Human errors: Unfortunately, human error is a common cause when data is lost from a NAS. Data loss often happens accidentally due to reformatting, reinstallation, deleting or overwriting a volume.
  • Power failure: NAS systems can become corrupt due to power failure, voltage fluctuations or overvoltage. RAID arrays (the storage inside the NAS) that have been in use for some time are particularly vulnerable, as voltage fluctuations can cause individual disks to be out of sync resulting in a degraded or failed RAID array.
  • Overheating:  Faulty cooling in the server room or an improper location in an office or at home can result in overheating and drive failures.
  • Defective NAS controllers: Defective controllers can cause errors during reformats or rebuilds. Errors in the firmware or operating system caused by reconfiguring the memory can cause data loss.
  • Mechanical errorsRAID systems are designed to compensate for the failure of one or more drives. As soon as a drive fails in a NAS/RAID, the remaining hard drives must compensate for the failure. Multiple drive failures can handicap the NAS/RAID to the point of complete failure.
  • Natural disasters: Fire damage, water damage, pollution and other contamination can destroy a NAS in seconds. Rebuilding a contaminated system requires special knowledge and the ability to thoroughly clean individual drives and other components of the NAS. Only then can the data be restored by a logical rebuild. Ontrack has the technical proficiency to thoroughly clean and successfully restore heavily soiled media.

Emergency Data Recovery 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 defragment drives that may be damaged.
  • Do not rebuild and/or reinstall the original system. Do not restore a backup to the same volume/drives.

Nas Case Studies

Ontrack is assisted by NetApp’s technology to solve a ransomware infection.

Feb 20, 2020, 16:37 PM
Title : Ontrack is assisted by NetApp’s technology to solve a ransomware infection.
Client :
A single user’s laptop at a large pharmaceutical company was infected with CryptoLocker ransomware.

This malware encrypts the user’s files and withholds the encryption key until you pay the ransom amount. The laptop was connected to the corporate network which allowed the malware to infect a CIFS volume which was set up as a file share on a NetApp FAS. The malware was able to infiltrate the file share and encrypt the majority of the files. The IT team was not notified of the infection until after the backup retention period had expired, meaning that the backup contained only encrypted data. The total impact resulted in inaccessible data on:

■ 46 drives

■ 1 aggregate

■ 1 volume infected on a RAID-DP

To perform the recovery, the aggregate needed to be taken offline, which affected 17 volumes in total.
The customer brought their 46 drives into our New Jersey lab for evaluation and Ontrack engineers got to work on a solution.

The engineering team from Ontrack:

■ Virtually rebuilt the RAID groups which were strewn across 10 different shelves

■ Virtually rebuilt the aggregate

■ Virtually rebuilt the critical volume

An additional challenge on this recovery was that the aggregate was in use for two weeks after the incident occurred which resulted in some data being overwritten.
Ontrack was able to virtually rebuild the volume containing the CIFS share and encrypted data.

Leveraging NetApp’s proprietary OS (OnTap) and file system (WAFL), Ontrack engineers used multiple consistency points to “walk back” in time to find and merge unencrypted copies of the critical data to return to the customer. This type of recovery is only possible on storage like NetApp’s FAS because of the way the data is stored on the volume.
