Local Cache
===========
In order to speed up certain operations, restic manages a local cache of data.
This document describes the data structures for the local cache with version 1.
Versions
--------
The cache directory is selected according to the `XDG base dir specification
<http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html>`__.
Each repository has its own cache sub-directory, consting of the repository ID
which is chosen at ``init``. All cache directories for different repos are
independent of each other.
The cache dir for a repo contains a file named ``version``, which contains a
single ASCII integer line that stands for the current version of the cache. If
a lower version number is found the cache is recreated with the current
version. If a higher version number is found the cache is ignored and left as
is.
Snapshots and Indexes
---------------------
Snapshot, Data and Index files are cached in the sub-directories ``snapshots``,
``data`` and ``index``, as read from the repository.
