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.
