CRYPTSETU...ERRESTORE(8) Maintenance Commands CRYPTSETU...ERRESTORE(8)
cryptsetup-luksHeaderRestore - restore a binary backup of the
LUKS header and keyslot area
cryptsetup luksHeaderRestore --header-backup-file <file>
[<options>] <device>
Restores a binary backup of the LUKS header and keyslot area from
the specified file.
NOTE: Using '-' as filename reads the header backup from a file
named '-'.
<options> can be [--header, --header-backup-file,
--disable-locks].
WARNING: Header and 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 already on the device and of the header backup
match. Alternatively, if there is no LUKS header on the device,
the backup will also be written to it.
--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 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
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 file with header backup file.
--help, -?
Show help text and default parameters.
--usage
Show short option help.
--version, -V
Show the program version.
Report bugs at cryptsetup mailing list
<cryptsetup@lists.linux.dev> or in Issues project section
<https://gitlab.com/cryptsetup/cryptsetup/-/issues/new>.
Please attach output of the failed command with --debug option
added.
