Restoring in-place
------------------
By default, the ``restore`` command overwrites already existing files in the target
directory. This behavior can be configured via the ``--overwrite`` option. The
default is ``--overwrite always``. To only overwrite existing files if the file in
the snapshot is newer, use ``--overwrite if-newer``. To never overwrite existing files,
use ``--overwrite never``.
By default, the ``restore`` command overwrites already existing files at the target
directory. This behavior can be configured via the ``--overwrite`` option. The following
values are supported:
* ``--overwrite always`` (default): always overwrites already existing files. ``restore``
will verify the existing file content and only restore mismatching parts to minimize
downloads. Updates the metadata of all files.
* ``--overwrite if-changed``: like the previous case, but speeds up the file content check
by assuming that files with matching size and modification time (mtime) are already up to date.
In case of a mismatch, the full file content is verified. Updates the metadata of all files.
* ``--overwrite if-newer``: only overwrite existing files if the file in the snapshot has a
newer modification time (mtime).
* ``--overwrite never``: never overwrite existing files.
