# A space-separated list of directories to prune from each backup.
# Key is a filesystem or host:dir spec as outlined above
# regular expressions allowed (not shell-type wildcards!)
+#
+# Note: These directories are actually regular expressions and must
+# match "find" output relative to the path of the current backup set. This
+# means that different exclusions are needed for different backup sets.
+# This is a little tricky, so, read on.
+#
+# The regular expressions are processed by "find" but, before "find" is run,
+# FlexBackup changes into the base directory of the backup set in progress.
+# FlexBackup then runs "find" with a path of "." which means all output lines
+# start with "./". To be helpful, FlexBackup packages each space-separated
+# prune directory as follows. If you have a prune list like this
+#
+# $prune{'/somedir'} = "one two three";
+#
+# then, the constructed -regex argument to "find" looks like this
+#
+# -regex "\./\(one\|two\|three\)/.*"
+#
+# The last thing you need to know is that FlexBackup only uses the prune
+# terms that match the current base directory in the set you're backing
+# up. For example, if your backup set definition looks like this
+#
+# $set{'daily'} = "/home /root /var /usr";
+#
+# and you want to do some exclusions in "/home" and "/var" (but not the other
+# directories), you must set up a prune list for those two directories
+# separately. For example, to exclude bert's and ernie's home directories plus
+# /var/tmp, you would need the following:
+#
+# $prune{'/home'} = "bert ernie";
+# $prune{'/var'} = "tmp";
+#
+# In particular, combining these *does not* work. For example, this
+#
+# $prune{'/'} = "home/bert home/ernie var/tmp";
+#
+# does not work, unless, of course, your backup set is backing up "/",
+# which our example is not.
