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.
