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.
