for the same reason. Therefore, partial checks may be useful only with very large
repositories where a full check would take too long.
The ``--verify-data`` option will perform a full integrity verification (as
opposed to checking just the xxh64) of data, which means reading the
data from the repository, decrypting and decompressing it. It is a complete
cryptographic verification and hence very time-consuming, but will detect any
accidental and malicious corruption. Tamper-resistance is only guaranteed for
encrypted repositories against attackers without access to the keys. You cannot
use ``--verify-data`` with ``--repository-only``.
