I just heard about unraid from Youtube channel Spaceinvader One. I'm a retired EE with abot 50 years starting with hardware/software embedded controller design. I've used Windows, OSX and various versions of Unix but have never really had to dig into an OS. (Embedded controllers were simple in my day. Programmed in assembly and C, with the OS consisting of a polling loop and maybe interrupts.)
I've been shooting video for many hears and have about 12TB of footage, photos and other assets scattered over many hard drives stored in my closet. What I want to do (when I get back to my home in Austin, TX next June) is to put together some improved comprehensive storage and archive system for most of that old stuff, but mostly for my new footage to come. I've looked at buying a NAS but somehow I find myself wanting to build my own. I don't want to think about off-site storage right now but I do want:
1) Some kind of protection against hardware failure causing data loss.
2) Some kind of automated backup that will be immured to ransomware attack.
I read a lot of stuff on the Unraid web site and understand what it does from the 30K view. What I don't know is and haven't found anything definitive is,
1) Why would I want this over FreeNAS?
2) What technology does Unraid use to prevent data loss in case of hardware failure?
3) Does Unraid have any kind of rollback in case of operator error? (The most likely data loss is if I make a mistake in deleting files. ("rm *")
Please feel free to point me to the documentation or any video tutorials that would help me understand Unraid at an intermediate level.
Best regards,
