 ## How to backup my Lightning Node?
 
-CAUTION: Restoring a backup can lead to LOSS OF ALL CHANNEL FUNDS if it's not the latest channel state. There is no perfect backup solution for lightning nodes yet - this topic is in development by the community.
+There are two ways of Backup:
+
+### 1) Securing your On-Chain- and Channel-Funds during Operation
 
-But there is one safe way to start: Store your LND wallet seed (list of words you got on wallet creation) in a safe place. Its the key to recover access to your on-chain funds - your coins that are not bound in an active channel.
+This is best done by auto backuping the 'channel.backup' file to a remote location. But it just secures the funds you have in your on-chain wallet or in your channels. On recovery the channels will get closed. For details on how to setup see the README:
+https://github.com/rootzoll/raspiblitz/blob/v1.2/README.md#backup-for-on-chain---channel-funds
 
-Recovering the coins that you have in an active channel is a bit more complicated. Because you have to be sure that you really have an up to date backup of your channel state data. The problem is: If you post an old state of your channel, to the network this looks like an atempt to cheat, and your channel partner is allowed claim all the funds in the channel.
+### 2) Making a complete LND data backup
 
-To really have a reliable backup, such feature needs to be part of the LND software. Almost every other solution would not be perfect. Thats why RaspiBlitz is not trying to provide a backup feature at the moment. But if you feel experimental and you look for a continues backup you may want to check out the following script to integrate into your RaspiBlitz: https://github.com/vindard/lnd-backup/blob/master/do-lndbackup.sh
+This backups all your LND data - including all open channels. But its just inteded to use when you move your LND data between computers, during update situations or in rescue recoveries. Because replaying out-dated backups can lead to losas of all channel funds.
 
 How to backup LND data in a rescue situation see next question "How can I recover my coins from a failing RaspiBlitz?".
