# Backup Umbrel
To backup umbreL, one must have access to some of the following:
1. Seedphrase
2. Static Channel Backup (SCB) file
## SCB backup
To have copy of the SCB always ready in Oli, in case that Banky's disk dies:
1. Make a local copy every minute
of `/media/data_disk/umbrel/lnd/data/chain/bitcoin/mainnet/channel.backup`
in `/media/data_disk/umbrel/app-data/syncthing/data/channel_backups/`.
2. Use syncthing to keep the files in sync wiht Oli.
Down the line, I should switch to storing the copies at Navaja, since Oli is
not always up an running.
