Topic: Can I burn my wallet on a DVD? - page 2. (Read 1914 times)

You can even store it on your playstation, but choose a more secure way instead.

Yes you can burn but also make the backup in other forms also.

It's actually a good idea to burn your wallet to the DVD and stash it somewhere. Going to use it for one of my wallets. Thank you for the idea

Just hold it (after making a paper wallet) and stick to a dvd then put it on fire! (on a safe place to avoid any damage to properties)

You mean like this ?

You'll just need to import it in your wallet.

thank you!

and btw, I have no idea why I just quoted myself, I thought I was editing my original post to be a little clearer. Whoops!

So after I drag it onto a blank cd, how would I go about using that data if, say, my computer was lost? If my computer can't ever 'find' the file, how do I get it to work?

All you need to do is burn it or just drag the wallet.dat file to new cd. Don't need to open it.

I engrave my wallet keys on a rock. I'm sure it will be there for a thousand years to come.

I feel like this is really dumb, but I plan on backing up my wallet.dat file to both cd's and flash drives.

But how exactly do I burn them there? I have never burned a cd that I can ever remember (I'm on a Mac) so want to make sure I do it right. Last thing I need is to go to the cd or flash drive to recover my wallet and have nothing there cause I messed it up. 

So for example I go into my wallet now and click "backup wallet" from the drop down menu. Then I would just save it to the external usb drive? How do I save it to the blank cd? Currently I just saved it to my "downloads" folder as a test, but my computer can't read it. So how do I actually open the thing?

Thanks!

Best to store in multiple dvd's and places

You can burn into dvd, but you have to keep it safe if your wallet is having lots of BTCBTC

While you have many valid points, there is a big difference between self burned CD/DVD's and factory "printed"/"burned" CD/DVD's. Those you make yourself are usually of a very bad quality and the chemicals used dont last very long. They decay over time and there is no way to resurface the CD/DVD if the chemical layer below the plastic is "gone". Storing data electronically for a very long time is still a problem today and there are very limited possibilties for home use. Out of those flash based memory (flash cards, usb sticky, etc.) is the most reliable. They are not perfect. They also suffer from "decay" as the magnetic fields that hold the data lose power, but they decay at a slower rate compared to the chemicals used in CD's.

If you want something to hold your data for a very long time: use stone or metal. Even "home use" paper might not hold your data over 5-6 years depending on the pen / printer ink you used.

How much bits are flipped each year due to background radiation I cant tell, since I have never read any reliable information about that. ECC might prevent people from noticing the effect while the systems are in use though. Same with xrays from static electricity. Sounds like bogus to me, but what do I know.

Edit:

Searched a bit on google scholar and found a paper on the topic. Its not the one I read, but its the same basic information, so I might as well give this as a reference.


Basically: Dont store valueable data on CD/DVD's.

As shorena said, cds and dvds can and do decay over time. Even if you leave it in a case protected from sunlight, temperature, scratching, etc it can simply lose data over a long period of time.

Anecdotal if you like, but I have never failed to recover data from a writeable optical disk, and I have some that are 15 years old now. On the other hand I've had several flash memory devices fail on me.

Also, you don't need a solar magnetic storm of the 1 in a hundred years variety to damage flash, lightning strike on the same block, utility transformer on in the neighbourhood blowing up, your own microwave oven catastrophically  failing, all of those could create a local EMP event big enough to disrupt data on flash storage.

Additionally, they are prone to bit rot from cosmic ray damage, the chances of a single bit error on these larger capacity devices are becoming close to a yearly event rather than the 10-15 years that lower density SRAM was thought to have for a risk factor in the 80s and 90s. If the device is in use regularly the single bit error may be corrected, close to when it occurs, if you leave it in a drawer for 3 years and it accumulates several errors, it may be unrecoverable. There are also local radiation sources that may be locally intense enough to cause errors, such as xrays from static discharges nearby (Such as when pulling scotch tape off the roll) and careless static discharges to the device itself.

Recovery; off optical media, do-able, you can resurface it, resilver it, recover most data off a disk sawn in half, recovery off corrupt/dead flash memory... good luck with that.

Of course, you can burn your walllet data on a DVD but you should be careful.

it is not a good idea, better use flash card

Since when do solar storms wipe out all the electrics on earth forever?

But when the next solar storm hits Earth and wipes out all Electronics and therewith bitcoins, I'm gonna be one of the few who's bitcoins survived.

How safe does that make you feel, if you saved it on an Electric unit?

You might have that problem with USB devices too, I doubt it though. You can still get floppy drives as well as old magnetic tapes.
