I hope before you do all this "backing up" that you verify the integrity of your wallets......

Check sum all relevant hashes (MD5,SHA1,SHA256,TIGER,Whirlpool,etc...)

Then verify fully by using PGP.

I think they goes a bit beyond what most people are capable of. Bitcoin will hopefully reach mass adoption some day, and that means making guidelines that the majority is at least able to follow.

You should have multiple backups. I think hard printing QR codes will be best.

o god

Here is the SAFE way of doing backups.

Make an encrypted backup. Encrypt the backup with winzip, winrar, 7zip. Anything that uses AES encryption will do. Use different passwords for the encrypted key itself and the encrypted archive. Strong passwords that you can remember so as not to write them in plain text for anyone to stumble across. Your head is the safest place to store vital information.

Next you will need 3 USB keys. Copy (or move, your choice) the encrypted archive with the encrypted wallet to USB1. Copy it from there to USB2. Copy it again from USB2 to USB3. Check if the backup on USB3 works, preferably on a clean test computer. Once verified immediately reformat the test computer. In this way you verify that all 3 sticks have working backups.

Distribute them in different physical locations. One in your pocket, one in a safe, one with a family member.

Check if the backups work every few months (or make new ones).

And done. You have safe backups that only you can access.

The more difficult question is how to keep a hot wallet safe.

Create a BIP38 encrypted paper wallet with bitaddress.org on an offline computer, take a screenshot of the QR code and/or alpha-numeric encrypted private key, and embed it in a PDF file of a very long, obscure book (The Bible, perhaps) on a page number that you will remember. Keep that PDF among many other PDF books, and make multiple backups of your collection on hard drives and in the cloud.

Just backup the private keys in different areas like paper wallet, usb storage and other devices. So even if you lost at one place, you can recover at other place.

Safekeeping encrypted files WALLET.DAT

The main problem of crypto-coin , I think the possibility of
loss ( theft, replacement) file purse WALLET.DAT.

I myself have encountered this . Even a few copies may be lost.
Can steal a laptop , external hard drive can be split , burn flash drive , and the drive to crush.

And all of this , the law of meanness, occurs simultaneously !

:::

It is interesting to find out how the service might be needed
for remote storage and organizing client encrypted files WALLET.DAT?
What conditions and nuances are important to customers ?

What should be the pricing?

:::

Taking into account all the wishes , I will be ready to provide this service to all comers,
with payment in BTC and any coins ...
