# Backup Wallet on an external device

One way to backup your wallet is to save a copy of the **wallet.dat** file on an external device.

First of all, we insert our USB stick into the PC and open our wallet (in our case the SAPP wallet), then go to the bottom left and choose the settings cog.

* 1 Settings
* 2 Wallet Data
* 3 Wallet

As seen in the image below:

Once this is done, as you can see in the image, the backup wallet menu will open, click on the folder icon on the right as in the image below:

After that, a window will open where we can choose the destination for our backup file

* 1 look for our USB stick and click on it to select it
* 2 let's choose a name for our backup
* 3 click on save

If the operation went well, this will appear:

If in case you need to restore your backup, the name to use will be "wallet.dat"
