## Optional: Dump Your Wallet
It might seem dangerous having all of your irreplaceable private keys in a single file. That's what `bitcoin-cli backupwallet` is for. It lets you make a copy of your wallet.dat:
It might seem dangerous having all of your irreplaceable private keys in a single file. That's what `bitcoin-cli dumpwallet` is for. It lets you make a copy of your wallet.dat:
```
$ bitcoin-cli backupwallet ~/backup.dat
$ bitcoin-cli dumpwallet ~/mywallet.txt
```
The `mywallet.txt` file in your home directory will have a long list of private keys, addresses, and other information. Mind you, you'd never want to put this data out in a plain text file on a Bitcoin setup with real funds!
You can then recover it with `bitcoin-cli importwallet`.
```
$ bitcoin-cli importwallet backup.dat
$ bitcoin-cli importwallet ~/mywallet.txt
```
But note this requires an unpruned node!
```
$ bitcoin-cli importwallet ~/backup.dat
$ bitcoin-cli importwallet ~/mywallet.txt

## Optional: View Your Private Keys
Sometimes, you might want to actually look at the private keys associated with your Bitcoin addresses. Perhaps you want to be able to sign a message or spend bitcoins from a different machine. Perhaps you just want to back up certain important private keys.
To look at _all_ the keys in your wallet, type `bitcoin-cli dumpwallet ~/mywallet.txt`.
Sometimes, you might want to actually look at the private keys associated with your Bitcoin addresses. Perhaps you want to be able to sign a message or spend bitcoins from a different machine. Perhaps you just want to back up certain important private keys. You can also do this with your dump file, since it's human readable.
```
$ bitcoin-cli dumpwallet ~/mywallet.txt
{
"filename": "/home/standup/mywallet.txt"
}
```
This will create a `mywallet.txt` file in your home directory with a long list of private keys, addresses, and other information. Mind you, you'd never want to put this data out in a plain text file on a Bitcoin setup with real funds!
More likely, you just want to look at the private key associated with a specific address. This can be done with the `bitcoin-cli dumpprivkey` command.
```
$ bitcoin-cli dumpprivkey "moKVV6XEhfrBCE3QCYq6ppT7AaMF8KsZ1B"

You can import any private key, from a wallet dump or an individual key dump, as follows:
