Snapshots, Data and Indexes

Snapshot, Data and Index files are cached in the sub-directories ``snapshots``,

``data`` and ``index``, as read from the repository.

Whenever a cache directory for a repo is used, that directory's modification
|
||||
timestamp is updated to the current time. By looking at the modification
|
||||
timestamps of the repo cache directories it is easy to decide which directories
|
||||
are old and haven't been used in a long time. Those are probably stale and can
|
||||
be removed.

The cache is ephemeral: When a file cannot be read from the cache, it is loaded
|

from the repository.
|
||||
|
||||
Within the cache directory, there's a sub directory for each repository the
|
||||
cache was used with. Restic updates the timestamps of a repo directory each
|
||||
time it is used, so by looking at the timestamps of the sub directories of the
|
||||
cache directory it can decide which sub directories are old and probably not
|
||||
needed any more. You can either remove these directories manually, or run a
|
||||
restic command with the ``--cleanup-cache`` flag.
