M-DISC

I kind of figured optical media was on the way out with the price of HDDs and flash media going way down. But the more I read about M-DISC, the more it seems like it would be good for making backups. Would it be better to go with this or stick with flash memory?

Relying on the backup media for security is babbys first backup tier thinking.

Instead, focus on duplication and recovery records and you can store your backups on anything.

Please show me where I said this was my ONLY backup solution. The question is that is it worth considering as part of a proper backup plan or is flash media better?

You obviously didn't understand my post.

Let me say it again:

If you focus on duplication and recovery records you can store your backups on anything.

Which means, M Dicsc are no better or worse than flash or anything else you can store bits on if you implement proper duplication and recovery records on you backups.

>You obviously didn't understand my post.

You're offering an answer to a completely different question.

They are better. Unless you're retarded enough to break them. BluRay ones are probably the best since they offer much more storage. It all really depends on what you want to back up.

I just keep my secondary backups on 3 thumb drives buried in the woods.
Once a month I visit the sites to collect the drives, verify and update them, and the deposit them again.

No I'm not.

If you do as I say you don't need to worry about which storage media to choose. If you keep focusing on the differences between flash and optical media it shows me that you don't understand that.

the cops have USB sniffing dogs now, you're fucked

They won't search several square kilometers of forest if they don't even know that I have drives there.

>implying they don't follow you already

Well so then be it.
I don't do anything illegal.

>you keep focusing on the differences between flash and optical media

That is the whole point of the thread. which you still can't seem to grasp. I don't give a shit about your backup tendencies or what methods you use to duplicate or journal your stuff. I'm purely interested in whether M-DISC is better for its durability or flash media is better because it has more of a future than optical media.

Your first post specifically states "But the more I read about M-DISC, the more it seems like it would be good for making backups.".

Which is pretty indicative of the fact that you think "better media durability = better for backups". Which is not necessarily true.

The only metric that matters for backup is (cost/$)/reliability.

Which HDDs wins by a big margin for total usable capacity

Durability is desirable if you want to backup information you need to last for a long time. Ideally this would go in a fire-safe container that would contain some other important things of mine. This stuff won't need to be updated on a regular basis, but it needs to last and be reasonably future-proof.

What you are suggesting may be good for general periodic backups, but that's not what I'm looking for in this particular case.

You make me angry with your stupidity, fuck.

If your goal is long term storage, you absolutely NEED redundancy and recovery records so that you can VERIFY THE INTEGRITY of you backup and RECOVER THE INFORMATION if parts of it or entire copies of it becomes UNREADABLE OR CORRUPTED.

What do you do if you shitty data gets a bit flip or bit rot or you get corrupted sectors or scratches in your fucking m disc or the data layer seperates from the substrate or the disk head scratches the platter or what ever else happens? Answer: You pull as many parts of the properly backed up data from as many intact sources you have and then rebuild it because you weren't a retarded cumstain so you had PARITY and SPLIT THE DATA.

Fuck.

Use three different storage media, HDD+flash+Optical, copy the same data to all of them, duplicate as much as possible. Make sure the data is parchived and split in chunks. Now fuck you you retarded cunt, I need a cigarette.

Not gonna keep bothering with someone who clearly can read but can't apply himself to do so. If you're gonna keep shitposting though, share some more birds of paradise. That was kind of neat, at least.

>I need a cigarette

When they tell you to kys on here, they don't mean it literally

Well then, go buy some m discs and store them in a safe. Done, and done, right?


If you do it my way, you can safe your shit on cheap ass DVDs and it will be many times more secure than the best m disc or what ever else you can find.

I mean, I could do that (I wouldn't), but what's the point if they last a thousand years but there aren't any optical drives being made in twenty years from now?

You don't just back up the data you should back up everything you need to retrieve said data. Which includes a couple of optical drives, as well as software and documentation for all relevant file formats.

If you plan on storing data for a very long time, migration should be a part of the plan.

>backups
>flash

Just use your old hard drive you retard.

>I only make a backup once every 20 years.

Are you my mom?

Unless you're backing up a ton of things (movies, games, porn), platter-based hard drives seem like only a step above dye-based DVDs in terms of fragility.

Fair enough.

>Unless you're backing up a ton of things (movies, games, porn), platter-based hard drives seem like only a step above dye-based DVDs in terms of fragility.

"Fragility" means nothing, that can be accounted for.

The only metric is longevity. Most storage media doesn't decay instantly but rather over time. So a medium may hold 100% of the information at year 5, 99% of the information at year 10, 80% of the information at year 15 and say 30% of the information at year 30. No problem, pull those 30% or so from each of the sources you have extract 100% of it. With parity and recovery records you don't even need to have 100% of it.

Since you've clearly done a lot of thinking about this, how do you do your own backups? Currently I keep a hard drive-based backup as well as a backup on the cloud, in addition to the original copies on my machines. The cloud copy gets updated immediately and I refresh the hard drive copies once a month.

Just use a strong laser to send your data to one of the NASA mirrors on the moon. Receive reflection and send again.
The moon is about 350000 km from Earth which means you can store about 2 light seconds of data. At 1 Gbps that would be about 250 Mb.

>The only metric is longevity.

Backups only have to last a month or two.

M-DISCs aren't for backups but for archival purposes. Duplication is the only viable backup option.

And flash media as well as the rest of optical discs are bad for long term storage. Magnetic storage as hard drives and tapes are slightly better but still not great.

So, that is what those "download RAM" sites meant.

Brilliant.

Would it be enough to place a mirror in my backyard, and just let the light bounce up and down until I need it?

I've heard blu ray is basically the same thing
and it stores much more
I've been looking into tape but might jist stick with swalping around harddrives
