Data Verification
=================
To prevent the upload of corrupted data to the repository, restic verifies that files can
be decoded and contain the correct data beforehand. This increases the CPU usage during
backups. If necessary, you can disable this verification using the option ``--no-extra-verify``.
However, in this case you should verify the repository integrity more actively using
``restic check --read-data``. Otherwise, data corruption due to hardware issues or software
bugs might go unnoticed.
To prevent the upload of corrupted data to the repository, which can happen due
to hardware issues or software bugs, restic verifies that generated files can
be decoded and contain the correct data beforehand. This increases the CPU usage
during backups. If necessary, you can disable this verification using the
``--no-extra-verify`` option of the ``backup`` command. However, in this case
you should verify the repository integrity more actively using
``restic check --read-data`` (or the similar ``--read-data-subset`` option).
Otherwise, data corruption due to hardware issues or software bugs might go
unnoticed.
