Backup your wallet
To backup file you need to backup the wallet.dat file located in your data storage directory. By default this is located in C:\Users\UserName\AppData\Roaming\Grailum unless you changed destination while doing the installation.
You can also backup the file from the program by selecting File -> Backup wallet... in the program menu.
