What has been described in the URL could've happened with a FreeNAS or TrueNAS or Open Media Vault system or just about any system. RAID is never a backup, and one backup is not enough.

  If you read the parent comment between the lines, it implies that Synology feels worry free in comparison to FreeNAS. My point is that both options have similar chances of breaking unexpectedly.

    It is also a fact that both meterorites and rain fall from the sky sometimes, but that doesn't mean the "chance" of a meterorite hitting my head are the same as a raindrop. You're only going to get actual, reliable and useful numbers about failure rates between competing products by doing actual studies and analyzing the aggregate results. Anything else is meaningless. And as a buyer, I'm more worried about things like warranty and technical support quality, frankly, if I'm going to buy a prepackaged system anyway, which are easier to gauge from afar.

The board on the NAS died, and took out a locally attached USB backup. He had recently turned off offsite backup. Instead of buying a replacement synology, and moving the drives (which are all fine) he dumped the data to various other devices using Linux raw LVM, and restored 100% of the data. This seems like it worked as intended to me (not counting the simultaneous loss of the USB stick and motherboard). Anyway, any NAS that contains important data should be backed up offsite.

> It’s clear that I not only need to replace my old solution, but I also need to come up with a more robust one too. Is there anything better than RAID? That's what every file system seems to use and it's honestly not very good. High capacity arrays can take over 24 hours to rebuild and during this time the risk of additional failures is even greater due to read errors. RAID also requires matching capacities for all storage devices, making it hard to expand capacity of the whole array. The only alternative I can think of is object storage which is not exactly made for home use.
