Check out the GNU Tar Reference manual, much more informative
than "man tar". Look for CACHEDIR.TAG and --exclude-caches, works
very well for me. The CACHEDIR.TAG file is added to any directory
you want to skip, and tar will skip it. Here's the contents:
$ cat /var/cache/CACHEDIR.TAG
Signature: 8a477f597d28d172789f06886806bc55
# This file is a cache directory tag created by (application name).
# For information about cache directory tags, see:
