Sorry to hear about the potential data loss on this device. It is not acceptable that you should experience data loss based on the scenario you have described. There are those who always chime in that RAIDis not a backup solution. But RAID should be able to give you some confidence that your data is safe if one drive fails. Otherwise, why spend the money?
As for off site backups over the internet, this solution is only viable when backing up a small amount of data. As a typical home consumer, the bandwidth available to backup T bytes of data is not practical. Cloud backup solutions should only be used for a very limited amount of data backup for the average user. I don’t even do cloud backup for this reason and due to the fact the cloud storage companies can come and go. I have decided to have an on-site back solution for the most part with drives kept in a waterproof, fireproof enclosure. I may consider backing up the most critical files to the cloud, but no one solution should be considered the end all be all.
Good luck. I hope your data is retrievable, and if not, that you did have a backup so nothing is lost. I am simulating various scenarios of drive failures on this NAS to determine if it will provide a level of confidence that I need to protect my data. Although this is not rocket science, unfortunately too many companies have given up their control of QA for the bottom line. Way too much outsourcing/insourcing to shops without the minimum level of talent to pull off even the simplest implementation of a closed system. For the most part, we are talking about moving bits. Nothing earth shattering here. I guess I could get on my soap box again, and maybe I should. It can not be emphasized enough that we are dealing with high unemployment among US citizen engineers, and yet we are allowing hundreds of thousands so-called qualified engineers into the US on H1-B Visas because we don’t have the talent to do the work ourselves. Give me a break. And along with the insourcing, so many companies are outsourcing. I am just feed up, and who wouldn’t be. Let’s hope as consumers, we can make a difference and not accept what is happening with corporate America.
