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 `__. 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.
