if you do not have a copy of something in different place, you do not have a backup. raid != backup!, its for reliability (and sometimes speed).
i actually have the local copy, a nightly backup to the nas device, and set of offline drives i keep in a pelican case i refresh a few times per year as a secondary backup.
I thought there was a raid setting where it basically duplicated the data across the drives such that if any one of them fail it can recreate the data. That should at least cover the "local" backup part. For more important things like family videos and such I have external drives that are offline unless I am uploading new videos and such. But really I should have some kind of offsite backup for that kind of stuff.
yes, that is what raid is but that is not a backup. it is making that single logical drive of your data resilient to a single drive failure. if anything goes sideways and you lose 2 drives, you lose 100% of your data. and it does happen. think power supply failure spiking your drives or whatnot.
you dont have to take my word for it, it is well known and well advertised that raid is not a backup.
yeah, I am totally with you. For the media server, I just don't know how much money I want to put into backing it up. For the important stuff. I really wish I knew of an offsite backup that I felt like I could trust. But most business models' these days seem to be hinged on hoping nothing ever goes wrong... or just paying if it does.
