Backup Wallet.dat

"1) I can backup my wallet by exporting a wallet.dat file. Do I have to do this everytime I receive more BBP? Or just whenever I add a new key? 2) How do I add new keys? 3) Can I generate and see the private key so that I can write it down/print it and store it somewhere safe?" -znffal
1) think of your wallet.dat file as your passbook in a passbook savings account. You have to have that .dat file to be able to access (and prove you SHOULD have access) to the BBP stored in your account addresses. Exporting it once is all you need.
2) Adding new keys? The passphrase (password) you use is the only "key" you would have in an encrypted wallet (besides the .dat file). If you mean new addresses, you can get those by going under File and Sending (or Receving) Addresses and hit "new".
3) Clicking Encrypt Wallet will be where you choose a passphase, I don't know you can see it other than when you enter it.
To put a real world example or two.
Example One: You don't ever encrypt or backup your wallet. If I borrowed/stole/hacked your computer, I could send all your coins to my wallet (no passphrase).
Example Two: You encrypt your wallet with the passphrase "secret" but don't backup the wallet.dat file, then your computer crashes and you lose all your data. Since you didn't have a copy of the wallet.dat file, your coins would be lost.
Example Three: You backup your wallet.dat but don't encrypt it. Your computer crashes and all your data is lost, but you re-download the QT program, restore your wallet.dat, all your coins are still in you wallet. But if you lose your USB drive that has the wallet.dat on it, and I find it, I can put your wallet.dat on another computer and send all your coins to my wallet.
Example Four: You encrypt your wallet and back up the wallet.dat file. If I hack/borrow your computer, unless I guess your passphrase your coins are safe. If you computer crashes, your can restore your wallet.dat file to another computer and your coins are safe.
In short, Encrypt your wallet (passpharse) and then backup (copy) the wallet.dat file to at least two locations." -616westwarmoth
"Find your wallet.dat file, copy it to a flash drive or any other secure place. If your computer crashes, you'll always have the wallet.dat and can put it on a new machine. It will have to resync a bit when you do, but you'll never lose your "key" to the wallet. Speaking of keys, you should password protect your wallet and make sure to remember it!"
"Yes you must have a copy of the wallet.dat somewhere. So multiple back up copies are a good idea. If you lose the wallet.dat file the coins will be in limbo but there will be no way to recreate the file. One thing to remember is it doesn't matter if the wallet.dat file is "current", it can be 10 years old on a flash drive and you can download a new client, put the wallet.dat file into the machine and you'll be good." -616westwarmoth
"In addition to this, whenever you reboot the node after more than 24 hours of being synced, we back your wallet.dat up into the "backups" folder. This is useful if you ever accidentally delete your wallet.dat.
Also, if you want a paper backup, you can do a 'dumpprivkey accountaddress' command from the RPC." -Rob
"wallet is a collection of private keys"
"there are other ways to achieve high security. You can make a new wallet, encrypt it with a long password, send coins to it, put it on a flash drive and put it in cold storage, then download the hard drive cleaning program and erase the wallet.dat sectors from your PC. And of course, keep a printed copy of the private key on paper and put it in a safe. Put the usb in the safe also. Burn a cd rom with the wallet.dat file and put it in the safe." -Rob

NOTE: As of version we have updated to HD wallets, so you should not need to worry about keypools anymore if you have upgraded
"Regarding the Sanctuary, you receive payments always to the same address (key), so the keypool is not consumed for those payments. But when you click to generate a new address on the "Receive" tab, one key will be deducted from the keypool. Also, sometimes new addresses are automatically generated and the keypool is consumed, for example when solo mining and finding a block, a new address could be used for the block reward.
You can always check your current keypool size by typing "getwalletinfo" in the RPC console and see "keypoolsize" and "keys_left". It's only concerning if they are a low number and you plan to generate new addresses in your wallet. They start from 1000. If the number gets too low, you can just type "keypoolrefill" to refill them back to 1000 and then you should backup the wallet. But from my experience the wallet automatically refills the keypool from time to time (or after certain actions like transactions), because I see that my wallet file keeps getting larger and the "keys_left" returns to 1000.
The only issue is if you actively use your wallet on multiple computers (for example cloud mining or simply sometimes using the wallet on your laptop), then one wallet could refill the keypool with new addresses and the other one will not, or they will generate different new addresses. If I understand this correctly, for example, you could receive a payment on a new address generated in one wallet; your old balance will be there on both wallets, but only the one wallet where you generated the new address would show the new payment. Then you should copy the wallet.dat file to other computers, to update them.
If you use the wallet on just one computer, you should just backup the wallet from time to time (or when you see it has increased in size). Qt also backups wallet.dat automatically, those can be found in the folder %AppData%\BiblepayCore\backups, you will see that they also have timestamps in their names and possibly different sizes." -inblue
