Bitcoin Core wallet backup in cold storage, safe enough in case of hard fork?
Hi all, I have a few Bitcoin Core wallet backups in cold storages (external drive, CD...) and I wanted to make if it'll be fine after the 1st August? I read many times that having control on our private keys is important. As wallet file contains the private keys, it should be fine? Will I have the same amount of unit for both bitcoin currencies after the fork? Thanks!
After I downloaded a file reader that doesn’t support .dat files, my backups of my Bitcoin Core wallet are now in VCD Video File format...please help.
I’m not sure how to get rid of this problem now that I have installed this file reader app on windows 10, but any advice would be great as to how I can get the files back to .dat format. Also, one thing I noticed is that when I save the file to the usb drive, the format is in .dat format but then it automatically converts it to this other format.
How to backup blocks on Bitcoin Core Wallet (Bitcoin-QT) ?
Hi, finally I have fully synced Core, but now I want to back up blocks, I will not keep Core installed for long so what do I need exactly to back up, just folder "blocks" ? If I uninstall Core completly then install it, and replace "blocks" folder with blocks, can I simply start Core it will start verify blocks and start sync from say 25 March 2015 ?
Have a backup of Bitcoin Core, how do I restore my bitcoin wallet.
So a few weeks ago, i transferred 0.124 btc to OPskins, which is a site for buying skins for a game called CSGO. I had around 0.003 btc left and sent that to a new blockchain.info wallet i had created. I created this new wallet because downloading 90gb of nodes for bitcoin core was really annoying and i heard you don't have to go through that for online wallets. I have a backup of my wallet, so is there anyway i can backup my bitcoin core wallet directly onto blockchain.info or do i have to do it through bitcoin core first then send it over to my blockchain account? Can you tell me how to proceed either way? Thanks a bunch!
PSA: Added Step May Be Needed When Restoring a Backup Encrypted wallet.dat to Bitcoin Core
TL;DR: To successfully restore an encrypted wallet.dat file, the instance of Bitcoin Core getting restored to needs to first have Encryption turned on and possibly the same Passphrase set as the wallet.dat file you are restoring. It seems this must be done before you restore your encrypted wallet.dat from backup, or Bitcoin Core will just show a zero balance. For the record, the set-up for this situation was as follows: Bitcoin Core (formerly Bitcoin-Qt) 0.9.2.1, Windows x86 version, on Windows XP Pro patched for 2019 PoS updates. Recently, my Bitcoin Core hot wallet had been acting up and crashing after about 6 to 12 hours of uptime. I thought that there was possibly some corruption in Core's database files, so I backed up my wallet.dat and started deleting block chain data/index files to see if a rescan or reindex would correct the problem. I tried to save time by not deleting everything, only certain file types. I managed to somehow screw up and got the dreaded "wallet.dat corrupt, salvage failed" message. Since I had a backup, I didn't bother trying the "-salvagewallet" command-line option (which might have actually corrected my problem.) Instead, I went straight for a restore from backup. Some time ago, and on a much older version of Bitcoin-Qt I had familiarized myself with the wallet.dat backup and restore process. I never had a problem with it. But thinking back, I may have done all of my testing with unencrypted wallet.dat files. In this case, I uninstalled Core, deleted everything in the Bitcoin data directory, reinstalled Core, used bootstrap.dat to catch up as much of the block chain as possible, and let the new install finish syncing from the Internet. Once Core was up-to-date, I closed it and restored my encrypted wallet.dat from backup. In my previous experience, I'd be done at this point. The next time I started the wallet, it would have automatically rescanned, and I'd be back in business. This time, when the wallet finally started up again, it showed no errors, the block chain was still fully synced up, but the wallet showed a zero balance. Not a good feeling. I thought maybe I'd need to manually start Core using the "-rescan" command-line option. I tried this, but got the same result. After mulling things over, I finally guessed that the problem might have something to do with Core's wallet.dat encryption. I again deleted the wallet.dat file from the Bitcoin data directory and restarted Core. Once it finished generating a new wallet.dat file, I enabled Encryption and set the same Passphrase as the wallet.dat file I was trying to restore. Core shut itself down to complete encrypting the new wallet.dat file. Next, I started Core once again to make sure all was OK with new encrypted but empty wallet.dat. I then closed Core and replaced the zero-balance wallet.dat file with my recent backup. That finally did the trick. On the next start, Core automatically did a rescan and my balance reappeared. I don't know for sure if this behavior is the same across all the different flavors of Bitcoin Core 0.9.2.1 (x64, OSX, Linux), but I suspect it might be. Also, it might work just to enable Encryption, but it might not be necessary to have the same Passphrase. I can only confirm that it worked in my case with the same Passphrase. This little adventure was unnerving, particularly since Core issues no errors and just insists there's a zero balance. I thought I should relate what I learned in case someone else encounters the same situation. Cheers, and to the moon! EDIT: At least a couple posts so far report not seeing the same behavior I did. I'm glad if it's a non-issue, and I can't explain why it happened to me. I can just suggest if you have similar issues, it might be worth it to give this method a try.

What exactly do I need from Bitcoin Core if I want to make a backup of wallet?
Using Bitcoin Core 0.10 as Wallet, my question is what do I exactly need if I would like to make a backup of my Wallet? I could copy the whole install folder (~50gb with everything). I could, but as I understood I do not need to right? Maybe also a second question: if I made a backup of my Wallet - once a time is enough I do not need to touch that backup again right? So I can use my non-backup Wallet forever and even if I would loose or delete that wallet my I just load my backup and I have everything as it should be right?
