Today, when you buy a product, there are chances that it will be “connected” and use cloud services for, at least, one of its features. I’d like to tell you a bad story that I had this week. Just to raise your awareness... I won’t mention any product or service because the same story could append with many alternative solutions and my goal is not to blame them.
I’ve multiple NAS at home with terabytes of data. You can imagine that the backup process for such amount of data is not easy. My backup plan is:
Last week, our city suffered from a major power outage and my UPS was unable to keep all the devices online. As a result, an unexpected shutdown of one NAS. When the power was restored, you can guess what happened: It did not boot at all: The OS was corrupted. After several attempts, I successfully restored a fresh operating system and, lucky me, the data were not affected. I started a rebuild the RAID5 and, a few hours later, I had access to all the data! Phew!
The next step was to reconfigure my backup configuration and “relink” the existing online backup with the new backup task. The procedure is described in the product documentation and looks very easy. I had all the required information (the most important was the encryption key). Except that it failed with strange error messages saying that some files were not found. After several unsuccessful attempts, I contacted the NAS manufacturer support and asked for some help. Followed the classic exchange of boring emails like “Are you running the latest version?” or “Did you turn it off and on again?”. Yesterday, I received the final reply (anonymised and simplified):
To read between the lines: "It's not our fault, check with the other party". I’m waiting for more feedback but it looks that my backup is lost (1.5TB of data). Hopefully, I did not lose data but I can’t imagine the disaster if I had to restore my complete backup from the cloud service. The conclusion of this story: Do NOT rely on cloud services only and make multiple backups. Keep in mind that, once you sent your data to the cloud, you completely lose control of them! Stay safe!
