Verification of ReadyNAS Duo Disk Upgrade Procedure

If you ever have any problems with the NAS, the backup is your data's life preserver. Never ever trust critical or important data to only one device. When I copy photos from my camera to the NAS, I wait until a backup has been performed before erasing them from the camera. An NAS no matter how many drives, no redundancy, single redundancy or dual redundancy is still just one device. Upgrades of the OS, and drive addition or replacement is when the array is most vulnerable. The resync process puts a lot of strain on all the drives because they are working hard for hours at a time.

If you ever get yourself into the position of adding a second ReadyNAS, the best backup device for a ReadyNAS is a second one. It is faster, and can be set up to automatically mirror the other (via rsync) on a scheduled basis. It took me three years to get to that point and I would not want to go back.
