* Make db dump more modular * Add basic backup and restore scripts * Exit on error * Exit with error code in case of missing file * Determine volumes location programatically A bit hacky, maybe there's a better way - open for suggestions! * gzip database dump * Restore database * Fail on pipe errors * Encrypt backup using gpg; improve log messages * Ensure database container is up during dump and import * Restore volumes

# - Old channel state is toxic and you can loose all your funds, if you or someone

|

# WILL LOSE ALL YOUR FUNDS IN A CHANNEL, because the counterparty will publish a
