Prevent data loss when using a RAID array

RAID levels are designed to protect against data loss caused by the physical failure of one or more of the hard disks. However, this doesn’t mean that data loss doesn’t occur.

There are a number of steps you can take to protect your business from data loss when using a RAID array, including:

  • Always have an up-to-date backup of your data
  • Choose a RAID configuration that is equipped to cover your data and data loss requirements
  • Never try to rebuild a system if too many disks have failed and the RAID level can no longer support itself
  • Monitor the status of the hard drives and always be prepared for a system or hardware failure
  • If you’ve lost your data and don’t know why the hardware failed, never attempt DIY data recovery.

If your RAID server has failed or you’ve lost data, our Canadian server data recovery team can recover your data and get your back up and running, fast.
