Oh, found out that I can use LVM for taking ext4 snapshots!
Yeah I've used lvm with snapshotting with great success. Raid is great, just remember it is only one measure for data retention. Another optional addition would be add a hot spare.
That’s what I missed during my setup. I’m currently stuck without the LVM layer. With LVM, I think you can also theoretically add lvmcache and throw SSDs in front of your RAID array to act as cache, thereby improving the performance of your array. That’s another thing worth considering if you’re just setting up now.
