New description:

 Tor puts a large number of large, rapidly changing documents in its
 DataDirectory, which defaults to /var/lib on many systems. This means that
 the size of backups blows out when running tor 0.3.1.1-alpha or later.

 If we added a CacheDirectory option, it could default to /var/cache (or
 the appropriate paths on other operating systems), and be ignored by most
 backup tools.

 This directory should contain
 * cached directory documents, including cached (micro)descriptors and
 consensuses, and compressed directory document diffs
 * any other files that tor can easily regenerate or re-download

 This might also benefit mobile users with small disks, but application
 size appears to be less of a priority for mobile developers than CPU or
 network usage.

 This is a breaking change for tools that expect to find consensuses in the
 data directory. Perhaps we should make CacheDirectory default to
 DataDirectory instead?

 relays/2017-November/013542.html
