services.tarsnap.archives.<name>.cachedir

The cache allows tarsnap to identify previously stored data blocks, reducing archival time and bandwidth usage.

Should the cache become desynchronized or corrupted, tarsnap will refuse to run until you manually rebuild the cache with tarsnap --fsck.

Set to null to disable caching.
