I posted a similar question on another forum and a user stated I was making a "NAS newbie mistake" for not using RAID. I still don't see how this is a mistake, maybe someone can explain...
this totally depends on what your other backup method is, and how large it is.
Now lets put it into this practice... suppose you have 12TB of Data....
There is no single 12TB backup outside using a TAPE.
GL uploading 12TB to the cloud.
Hence ur backup will be most likely be partitioned on several disks, or wont be a complete backup.
Raid is not a real backup, but it will save you some because you just replace the drive you have lost, not go though archive and re-download / reinstall 12TB of data.
Again RAID is not a real backup, but its a first line saftey net to somehow protect your not so critical information..
Priceless files... like pictures you can never lose, should always be backup'd on multiple backup options, including a cloud service.
If your server catches fire.. or you house catches fire... no form of backup which was at the location will save you unless ur (nature proof'd the vault) or the data is at an offsite location.
