What is the most reliable way to back up my anime?

What is the most reliable way to back up my anime?
I have a bunch of high-quality series I want to be able to access whenever (and from any mainstream OS). I'd buy an external hard drive but if it breaks I'm fucked.

dropbox

This might actually be the most reliable, but I don't want to pay out of the ass every year for 1+TB of file hosting.

inorganic(non-LTH) BD-R

make a bittorrent and just seed it. Eventually other people will get it and just store the small torrent files everywhere.

How is that related to what I'm asking?
Sounds pretty unpractical though.

It will last until you die.

Burning everything to BD-R discs?
Is it really the physical support that's the least likely to fail?
It would take a lot of time and discs to store close to 1TB of media.

Smaller (or big ones if you can afford) pairs of external hard-drives. Sony, Toshiba, or Samsung (or at least NOT Seagate or WD). Arranged in RAID. Or use them to make back-ups (as in the old school: copy everything to both disks, check they are actually equal, and keep them stored at least 500 mts. away from each other). There are no other answers...

You don't need to burn them all at once. 50 disc spindle is cheap.

Hi!
Go to hell.

NAS with >3 HDDs in RAID6

Buy two of those WD 8tb things that go on sale, shuck the HDDs and put them in a raid setup. 7.2TB of animu backup.

RAID 5 and 6 are bad jokes and anyone who suggests either should be taken out into the streets and shot.

It seems like HDD is the best choice, or there is none without drawbacks
>Cloud services
won't last forever, account can be banned for muh piracy, limited space, annually paid, years of up/down times depending of anime Quality. I'm guessing if you looking for such solutions, you don't store 720p 4GB total series, but rather 2GB per episode.
>BD discs
won't last forever + they actually take space + you actually have to have optical drive + it would be shit to put more than one series on a disc
>HDD
might break, but realistically how often do you break your HDD? Cheap GB/$, can seed from storage, can just add more HDD to the multi HDD case.

What are the most reliable HDDs currently on the market?

What would you use instead?

How many animes can you put on a HDD, just a ballpark figure is ok?

Depends on the size of your series
Just a dozen series of 25 episodes each take around 500GB of space for me

FreeBSD + ZFS + ECC + RaidZ/Raid10

>shitty meme

Yu sit ap a fileservur.

Standard RAID 1 for two, RAID 1E for three, and RAID 10(f2) for more than that. All implemented through bog-standard md.

RAID 5 and 6 come from a time where a terrabyte disk was the height of luxury - meaning most rebuilds were intensive but short. In 2017, a 4TB disk starts at $100. Rebuilding that will thrash the shit out of the disks that haven't dropped for at least a full day, more than likely hitting an uncorrectable read error. I'd argue that RAID 6 is just RAID 5 with the inevitable URE accounted for. I don't suggest ZFS's Z1/Z2/Z3 for the same reasons, although its on-line error correction does make it far less of a worry, and a viable option for people with a sizable budget.

Legitimately, for home use, something like HAMMER's mirror-stream or a script using inotifywait and rsync is enough. One for daily use with one as an online backup is more than most people would ever need.

I just use a NAS and stream everything with plex when I'm out.

Whats the best site to download shows?

Thank you user

Buy 2 boxes in 2 different datacenters, throw the shit on raid 6. You can also look into aws.

then it wasn't a backup

for some reason, a few people seem to think a backup is when you move data to a permanent storage location
this is not the case, a backup is a additional copy of data, if you move the data, it no longer exists at the original location, and you have not made a copy

>not using ZFS
What is wrong with you, user?
