Lightning Labs currently has a warning to users who are using Taproot Assets on their Lightning Terminal app (Release Lightning Terminal v0.12.1-alpha · lightninglabs/lightning-terminal · GitHub). Uninstalling Lightning Terminal from your Umbrel will delete tapd data and can result in permanent loss of assets/funds if you have not backed up tapd data from your Lightning Terminal installation.
Currently there is no way to backup tapd data from the Lightning Terminal app through its UI, and there is no simple way to backup app data on Umbrel (yet ). So as an interim measure people can back up their tapd data by following these steps:
- Create a directory to store your backup files:
- You can create a directory on your computer or on an external drive
- Run the Backup Command:
Open a terminal on your computer and execute the following command to copy the tapd data over to your local machine.
<path/to/backup/directory/on/local/machine/>with the folder path where you want the backup to be saved on your computer/external-drive.
If you’re on Linux and your Umbrel installation directory is different, replace
~/umbrelwith your specific installation path.
You may be asked to type in a password. This is the password to your Umbrel device (the same one you use to log in to the dashboard). Nothing will show up in the terminal as you type your password, so just type it in and press ‘Enter’.
scp -r email@example.com:~/umbrel/app-data/lightning-terminal/data/.tapd/ <path/to/backup/directory/on/local/machine/>
To back up tapd data to
/Users/nmfretz/lightning-terminal/backup/on a Mac, you would run:
scp -r firstname.lastname@example.org:~/umbrel/app-data/lightning-terminal/data/.tapd/ /Users/nmfretz/lightning-terminal/backup/
- Viewing the Hidden tapd Directory:
The tapd data directory is hidden (it starts with a dot:
.tapd), so it won’t show up in normal file listings.
To see it, use the
ls -acommand in its parent directory in the terminal, or else enable viewing hidden files/folders in your File Explorer.
