dcrlncli verifychanbackup - Verify an existing channel backup

### Usage¶

   dcrlncli verifychanbackup [command options] [--single_backup] [--multi_backup] [--multi_file]


### Description¶

This command allows a user to verify an existing Single or Multi channel backup for integrity. This is useful when a user has a backup, but is unsure as to if it’s valid or for the target node.

The command will accept backups in one of three forms:

• A single channel packed SCB, which can be obtained from exportchanbackup. This should be passed in hex encoded format.

• A packed multi-channel SCB, which couples several individual static channel backups in single blob.

• A file path which points to a packed multi-channel backup within a file, using the same format that lnd does in its channels.backup file.

### Options¶

Option Info
--single_backup value a hex encoded single channel backup obtained from exportchanbackup
--multi_backup value a hex encoded multi-channel backup obtained from exportchanbackup
--multi_file value the path to a multi-channel back up file
