exportchanbackup
dcrlncli exportchanbackup - Obtain a static channel back up for a selected channels, or all known channels
Usage
dcrlncli exportchanbackup [command options] [chan_point] [--all] [--output_file]
Description
This command allows a user to export a Static Channel Backup (SCB) for
a selected channel. SCB’s are encrypted backups of a channel’s initial
state that are encrypted with a key derived from the seed of a user. In
the case of partial or complete data loss, the SCB will allow the user
to reclaim settled funds in the channel at its final state. The
exported channel backups can be restored at a later time using the
restorechanbackup command.
This command will return one of two types of channel backups depending on the set of passed arguments:
-
If a target channel point is specified, then a single channel backup containing only the information for that channel will be returned.
-
If the
--allflag is passed, then a multi-channel backup will be returned. A multi backup is a single encrypted blob (displayed in hex encoding) that contains several channels in a single cipher text.
Both of the backup types can be restored using the restorechanbackup
command.
