# cryptsetup-luksHeaderRestore

## NAME



           cryptsetup-luksHeaderRestore - restore a binary backup of the LUKS
           header and keyslot area
    


## SYNOPSIS



           **cryptsetup** _luksHeaderRestore_ **--header-backup-file <file>**
           **[ <options>] <device>**
    


## DESCRIPTION



           Restores a binary backup of the LUKS header and keyslot area from
           the specified file.
    
           Using '-' as a filename reads the header backup from a file named
           '-'.
    
           All keyslots will be replaced; only the passphrases from the
           backup will work afterward.
    
           This command requires that the volume key size and data offset of
           the LUKS header and backup match. Alternatively, the backup will
           also be written if the device has no LUKS header.
    
           **< options> **can be [--header, --header-backup-file,
           --disable-locks].
    


## OPTIONS



           **--batch-mode** , **-q**
               Suppresses all confirmation questions. Use with care!
    
               If the --verify-passphrase option is not specified, this
               option also switches off the passphrase verification.
    
           **--debug** or **--debug-json**
               Run in debug mode with full diagnostic logs. Debug output
               lines are always prefixed by **#**.
    
               If --debug-json is used, additional LUKS2 JSON data structures
               are printed.
    
           **--disable-locks**
               Disable lock protection for metadata on disk. This option is
               valid only for LUKS2 and is ignored for other formats.
    
               **WARNING:** Do not use this option unless you run cryptsetup in a
               restricted environment where locking is impossible to perform
               (where /run directory cannot be used).
    
           **--header** _< device or file storing the LUKS header>_
               Use a detached (separated) metadata device or file where the
               LUKS header is stored. This option allows one to store the
               ciphertext and LUKS header on different devices.
    
               For commands that change the LUKS header (e.g., _luksAddKey_),
               specify the device or file with the LUKS header directly as
               the LUKS device.
    
           **--header-backup-file** _file_
               Specify a file with the header backup file.
    
           **--help** , **-?**
               Show help text and default parameters.
    
           **--usage**
               Show short option help.
    
           **--version** , **-V**
               Show the program version.
