It's nice and simple, but there are some aspects that seems to be ignored and noobs don't know this:
- recovering LN channels MUST be with the latest state, not any other previous state. Using a previous state of the channels could end up with a punishment if some peers are using watchtowers and user can lose ALL FUNDS or partial. So that option to select different states is dangerous and useless, only the last state is valid!
- the demo is not talking about wiped out node data, is only on the same disk, when was removed and added again the same file structure of LND. That means the backup file was already there, in the backup folder in the node's disk. Add option to upload the backup file from any location you have, then start the recovering funds procedure (by closing the channels).
Anyways, Umbrel fucked up the whole idea of a node machine after the version 0.5. Sad.

Curious can you update LND without updating your umbrel. I don’t want to upgrade to 0.5 but I want my LND to remain current

Simple: move your node from Umbrel to Raspiblitz, Embassy or MyNode.
See option 6 or 7 from my SHTF guide.
Umbrel fucked up the whole folder structure in v 0.5 so it will be a nigtmare for you to dig up into docker repositories and yml files to fix that. Total mess.
Basically, make an offline backup of your LND database, out of your node disk, then install any other node bundle with LND and let it start sync a bit. Then stop it, shut down, and copy over the backup files of wallet.db and channel.db, as described. Start the node and voila, all back again.

This closes all of your channels right?

No, option 6 and 7 is not about SCB backup. Is full copy of the dbs. Pay attention to details explained in that guide.

There seems to be something off here(?) as Darth mentions in his comment here, it seems like the data is already in the disk and they simply perform a normal channel close from the data backup. You can see that it's a normal channel close by seeing the total balance in the end and comparing it with the balance in the beginning of the video..just some 390 sats of difference, which looks like the fees for two 1sat/vB transactions.
So misleading by using the phrase "nuking our lightning node". You aren't nuking jack shit here buddy. Just doing an "uninstall app" doesn't convince me or any rational person. I want a video of you taking a drill and going to town on the pi and ssd/hdd and then recovering your funds. Also, the proper way of recovering from the channel failures is using SCBs on lnd and not using the channel.db backup. You aren't even supposed to keep backups of channel.db.
